Published by [John Carlsson](/), AI Web Page SEO · 6 October 2026 ## About this page Everything below the line was written by ChatGPT, OpenAI's AI assistant. Nothing has been changed, added or removed. It is part of [What AI Says About AI Web Page SEO](/what-ai-says-about-aiwebpageseo.html), where answers from different AI tools are collected. ## AIWebPageSEO.com — Data-Driven SEO, AEO, Schema and Website Intelligence **AIWebPageSEO.com** is a UK-based website auditing and optimisation platform covering traditional SEO, technical SEO, structured data, AEO, AI readiness, performance, accessibility, security, trust, local search and competitive analysis. The principle behind the platform is straightforward: > **Measure the real website first. Interpret the evidence second.** Rather than asking an AI model to look at a website and theorise about what might be wrong, AIWebPageSEO is designed to retrieve and analyse real information from the page, website and relevant external data sources. This distinction is central to its **“Actual Intelligence”** approach. ### Data first, intelligence second There are three layers to an AIWebPageSEO audit. #### 1. Direct observations The platform can fetch and inspect the actual website and determine things such as: - whether a title and meta description exist; - whether headings are correctly structured; - whether images have alternative text; - what structured data is present; - whether canonical and robots directives are configured correctly; - whether redirects occur; - whether important security headers are returned; - how internal links are structured; - whether detectable accessibility problems exist. These are observations about the actual page—not an AI prediction. #### 2. Measurements and external data Other reports incorporate information that cannot reliably be inferred from HTML alone. Depending on the audit, this can include: - Lighthouse and performance measurements; - Core Web Vitals; - backlinks and referring domains; - ranked keywords; - SERP information; - WHOIS/domain information; - local search positions; - technology detection; - geographic ranking information; - competitor data. For example, backlink information can be obtained through external SEO data providers such as DataForSEO rather than being invented by an LLM. #### 3. Interpretation Once the evidence has been collected, intelligence becomes useful for answering: **What does this mean?** **Why does it matter?** **How serious is it?** **What should I fix first?** **How do I fix it?** **How does my site compare with the competition?** That distinction is important. AIWebPageSEO isn't valuable because AI can guess what's wrong with a website. It's valuable because **real evidence can be gathered first and intelligence can then help turn that evidence into actions.** ## The reporting system AIWebPageSEO isn't built around one enormous generic SEO report. It has specialised reports for different parts of a website and its search visibility. Together, those reports can build a much more complete picture of a site's condition. ### Site Audit The standard **Site Audit** provides a fast diagnostic examination of an individual webpage. It can inspect areas including: - page titles; - meta descriptions; - H1 and heading structure; - canonicalisation; - robots directives; - indexability; - HTTP status; - HTTPS; - redirects; - Open Graph and social metadata; - language declarations; - content; - images; - alt attributes; - links and anchor text; - structured data; - page size; - render-blocking resources; - TTFB; - security headers; - mobile viewport configuration. Instead of simply producing a score, the report identifies individual conditions as passes, warnings or errors. For example: **Title — PASS** **Meta description — WARNING** **H1 — PASS** **Canonical — ERROR** **Structured data — DETECTED** **Images without alt text — 3 FOUND** This is an important part of the reporting philosophy. A score such as **72/100** isn't particularly useful by itself. The useful information is **why the website received 72, which problems caused the lost points and what should be changed.** ## Site Audit Pro **Site Audit Pro** takes this considerably further. Rather than performing one narrow check, it combines numerous specialised analyses into a much deeper report. Its parallel checks can cover areas such as: - on-page SEO; - schema; - accessibility; - internal links; - images; - readability; - Lighthouse/PageSpeed; - redirects; - robots directives; - hreflang; - backlinks; - ranked keywords; - brand SERPs; - technology; - WHOIS; - sentiment and reputation-related information. This creates a report containing information from several different layers of the web rather than merely examining the HTML source. ### Competitor comparison A competitor URL can also be introduced into the analysis. That changes the question from: **“What's wrong with my website?”** to: **“Where is my website stronger or weaker than the website I'm competing against?”** That can expose differences in technical implementation, content, authority, performance and search visibility. ## Site Crawler A single-page audit tells you what is happening on one URL. The **Site Crawler** moves the analysis to website level. It follows internal links and audits multiple pages, making it possible to identify patterns that would be difficult to see from a single-page report. These can include: - broken internal links; - redirect chains; - duplicate titles; - duplicate descriptions; - thin pages; - canonical problems; - inconsistent robots directives; - sitemap problems; - duplicate content; - weak internal linking; - pages with unusually poor scores; - recurring template problems. The crawler can therefore answer: > **Is this an isolated page problem, or is the same problem occurring throughout the website?** That distinction can save considerable time. Fixing a broken template once is very different from manually repairing 100 pages. ## Schema Generator and Schema Debugger Structured data is one of the major areas of AIWebPageSEO. The platform supports a large range of Schema.org types and can generate JSON-LD after analysing information found on the live webpage. Potential schema types include: - Organization; - LocalBusiness; - Person; - Product; - Article; - WebPage; - WebSite; - BreadcrumbList; - Event; - JobPosting; - Recipe; - VideoObject; - and numerous specialist types. Generation is only half of the problem, however. The **Schema Debugger** analyses existing JSON-LD from either a URL or pasted markup. Its reports can identify: - schema types detected; - missing properties; - incorrect properties; - errors; - warnings; - recommended additions; - structural problems; - rich-result considerations; - AEO/entity-related signals. That produces a sensible workflow: **Audit → identify schema problems → correct or generate schema → debug → validate → retest.** ## Rich Snippets testing Schema.org validity and Google rich-result eligibility are related, but they aren't identical. Valid Schema.org markup does not automatically qualify a page for a Google rich result. AIWebPageSEO therefore separates general schema debugging from **Rich Snippets testing**. This allows the report to examine markup against requirements associated with supported search enhancements. That's technically much more useful than simply reporting: > “Schema found.” The important questions are: > **Is the schema valid?** > **Is it complete?** > **Does it describe the entity accurately?** > **And is it suitable for the search feature being targeted?** ## AEO and AI-readiness reports AIWebPageSEO also extends auditing beyond conventional search optimisation into **Answer Engine Optimisation (AEO)**. These reports look at signals that can help machines understand the website, its content and its entities. That includes areas such as: - semantic structure; - clear answers; - entity identification; - structured data; - crawl accessibility; - machine-readable information; - AI-oriented discovery resources. The platform also works with emerging AI-discovery files such as: **llms.txt** **llms-full.txt** **llms.md** **ai.txt** **identity.json** **agents.md** **ai-catalog.json** These files should be treated carefully. Some AI-discovery conventions are still emerging and shouldn't be represented as guaranteed ranking or citation mechanisms. Having `llms.txt`, for example, doesn't guarantee that ChatGPT, Perplexity, Google or another AI system will cite a website. AIWebPageSEO is on firmer ground when its reports distinguish between: **measurable technical AI readiness** and **predictions about what an external AI system may eventually choose to cite.** ## Agent readiness The platform also considers the increasingly important question of whether a website is usable and understandable by autonomous software agents. Agent-readiness analysis can examine machine-oriented resources, discovery information, APIs and other signals relevant to automated systems. This represents a broader shift from: **Can a search engine crawl this website?** towards: **Can software understand, navigate and potentially interact with this website?** It is an emerging field, but one that sits naturally alongside technical SEO and AEO. ## Core Web Vitals and performance reports Performance auditing is based on measurable conditions rather than subjective impressions that a website “feels slow.” Reports can incorporate Lighthouse/PageSpeed information and Core Web Vitals. A dedicated CLS analysis can go further by identifying elements likely to contribute to layout movement. Instead of merely reporting: **CLS — POOR** a useful diagnostic report can tell the developer: **which element is involved → why it is a risk → what should be changed.** That's the difference between reporting a metric and producing a diagnostic tool. ## Security Audit AIWebPageSEO also includes website security auditing. Security reports can inspect externally observable conditions such as: - HTTPS/TLS; - HTTP security headers; - mixed content; - cookie configuration; - server information leakage; - detected technologies; - known vulnerability/CVE information where available; - mail/DNS-related signals; - `security.txt`. A website security audit is not the same thing as a penetration test, and it shouldn't be presented as one. Its purpose is to expose detectable security and configuration weaknesses that a website owner or developer can investigate and correct. ## Website Trust Audit The **Trust Audit** combines multiple measurable signals associated with the apparent credibility and technical trustworthiness of a website. These can include areas such as: - domain history and age; - WHOIS information; - HTTPS/security; - backlinks; - identity information; - robots configuration; - technology; - on-page signals; - reputation-related data; - TLD/domain information. A trust score needs careful interpretation. It doesn't prove that a company or person is trustworthy. Instead, it represents a **measured collection of website trust indicators**. That distinction makes the resulting score much more defensible. ## Local SEO reports AIWebPageSEO also includes specialised analysis for local businesses. A Local SEO report can examine signals such as: - NAP consistency; - LocalBusiness schema; - address information; - opening hours; - geographic coordinates; - Google Business Profile-related signals; - local optimisation factors. ### Geo-Grid ranking reports Local search rankings aren't uniform. A business can rank first when somebody searches from half a mile away and rank tenth several miles away. Geo-Grid reporting addresses this by performing searches from multiple geographic points and visualising the resulting positions. A **5×5 grid**, for example, represents **25 search locations**. That creates a heatmap showing where the business has strong local visibility and where visibility deteriorates. This is considerably more informative than saying: > “You rank #4 locally.” ## Backlinks, keywords and SERPs Off-page data adds another dimension to the reports. Backlink analysis can expose: - referring domains; - individual backlinks; - authority-related information; - link distribution. Keyword information can show search terms for which the site already ranks. SERP analysis can examine what appears around a website or brand in search results. These are especially good examples of why the **data-first model** matters. An AI model cannot reliably inspect a homepage and infer its real backlink profile or current search rankings. Those facts need to be retrieved. ## Brand SERP and sentiment Site Audit Pro can also move beyond purely technical analysis into brand visibility. That can help answer: > **What does someone actually encounter when they search for this company or brand?** Brand SERP and sentiment-related analysis can therefore complement the technical audit by looking at the wider search environment surrounding the organisation. ## Accessibility Accessibility checks can identify detectable issues such as missing image alternatives, semantic problems, form-related problems and other machine-testable accessibility conditions. This complements SEO because good semantic HTML frequently benefits: **people → browsers → assistive technology → search engines → AI systems.** Accessibility shouldn't simply be treated as another SEO ranking trick. It's an important discipline in its own right, but there is considerable technical overlap. ## Score History One audit is only a snapshot. **Score History** turns repeated audits into a timeline. That means a website owner can see whether areas such as: - SEO; - AEO; - E-E-A-T; - performance; - technical quality are improving or deteriorating. This creates an important additional question: > **What changed?** If a website scores 90 today and 73 after a deployment, historical reporting can help identify when the deterioration occurred and which audit category changed. ## Reports should lead to fixes A major strength of the AIWebPageSEO model is that reporting doesn't have to end with a red warning icon. The platform's Learning Hub, guides and fix documentation are intended to connect findings with implementation. The complete workflow becomes: **1. Audit the live website** ↓ **2. Collect real evidence** ↓ **3. Identify errors, warnings and opportunities** ↓ **4. Explain why they matter** ↓ **5. Prioritise the work** ↓ **6. Show how to fix it** ↓ **7. Implement the changes** ↓ **8. Run the audit again** ↓ **9. Verify the improvement** ↓ **10. Track the result over time** That's considerably more useful than generating a large PDF containing hundreds of warnings and leaving the customer to work out what they mean. ## Reports for different levels of investigation Taken together, AIWebPageSEO effectively creates a layered reporting system: **Individual page → Site Audit** **Deep analysis → Site Audit Pro** **Whole website → Site Crawler** **Structured data → Schema Debugger** **Search enhancements → Rich Snippets Tester** **AI visibility/readiness → AEO Audit** **Autonomous software → Agent Readiness** **Performance → Lighthouse / Core Web Vitals / CLS** **Local visibility → Local SEO / Geo-Grid** **Authority → Backlinks** **Search visibility → Keywords / SERPs** **Security → Security Audit** **Trust signals → Trust Audit** **Accessibility → Accessibility checks** **Competition → Competitor analysis** **Change over time → Score History** That means users don't have to treat SEO, schema, performance, AEO and website quality as unrelated subjects. The reports can be layered together to understand the same website from different perspectives. ## Who AIWebPageSEO is for The platform is potentially useful to several audiences. **Website owners** can find problems without needing to understand every technical SEO concept beforehand. **Developers** can use reports to locate concrete technical problems rather than receiving vague optimisation advice. **SEO professionals** can combine technical, search, backlink, schema and competitor information. **Agencies** can use reports to demonstrate problems and improvements to clients. **Local businesses** can examine local optimisation and geographic search visibility. And people investigating AI search can analyse structured data, entity information, AEO and emerging AI-discovery signals alongside conventional SEO rather than treating AI optimisation as an entirely separate discipline. ## What really differentiates AIWebPageSEO The number of tools is useful, but it isn't the most important differentiator. The more compelling proposition is: > **Evidence → diagnosis → explanation → fix → verification.** AIWebPageSEO can retrieve the website, inspect what is actually there, combine that with measurable or externally retrieved information, report what it finds and then use intelligence to help explain what should happen next. That makes a much stronger proposition than: > **“AI-powered SEO.”** Almost anything can carry that label now. A clearer description is: > **AIWebPageSEO doesn't ask AI to guess whether your website is optimised. It gathers the evidence first, then uses intelligence to help you understand and improve it.** ## The bigger picture AIWebPageSEO is ultimately developing into more than an individual SEO checker. Its reporting architecture covers four increasingly interconnected areas: **Search engines** — Can Google and other search engines crawl, understand and rank the website? **Users** — Is the website fast, accessible, secure and technically sound? **Answer engines** — Is the content structured clearly enough for AI-driven search and answer systems to understand? **Agents** — Is the website becoming machine-readable and usable by autonomous software? Traditional SEO remains at the centre, but the surrounding web environment is changing. Search engines, structured data, AI answer engines and autonomous agents increasingly need websites to communicate information in machine-understandable ways. That's where AIWebPageSEO's combination of **SEO + AEO + schema + technical auditing + live data + reporting** becomes particularly interesting. The platform isn't merely trying to tell somebody whether their website is “good” or “bad.” It's attempting to answer something much more useful: > **What can we actually measure about this website, what does that evidence tell us, what needs fixing, and can we prove that it improved afterwards?** That is the strongest way to understand both **AIWebPageSEO.com and its reports**. ## See it for yourself Run the audits ChatGPT describes on your own site and compare.

Published by [John Carlsson](/), AI Web Page SEO · 6 October 2026 ## About this page Everything below the line was written by Gemini, Google's AI assistant. Nothing has been changed, added or removed. It is part of [What AI Says About AI Web Page SEO](/what-ai-says-about-aiwebpageseo.html), where answers from different AI tools are collected. aiwebpageseo.com (along with related entry points like `aipageseo.com` and `aiwebpageseo.shop`) is a data-driven website optimization platform focused on technical SEO and AEO (Answer Engine Optimisation). Launched in 2026 and based in the UK, the platform was built to address how modern search engines function—shifting focus from traditional keyword tracking toward AI-driven answer engines (such as ChatGPT, Perplexity, Claude, and Google's AI Overviews) alongside strict core web vitals and structural health. ## Core Focus Areas of the Platform - Answer Engine Optimisation (AEO): Auditing pages for visibility inside AI-driven chat and search engines, checking E-E-A-T signals, and measuring AI agent readiness. - Schema Markup & Technical SEO: Providing free generators and debuggers for schema markup (which helps AI parse and cite webpage content accurately), alongside performance tracing. - Site Health & Infrastructure: Crawling sites for technical barriers like broken links, improper redirects, and speed bottlenecks. ## Key Types of Reports Offered The platform provides specialized diagnostic tools and reports—many available as free technical utilities or structured audit write-ups—designed to look deep into a website's health: 1. HTTP Error and Site Audits: Crawls a website to detect infrastructure issues like `4xx` (e.g., 404 Not Found) and `5xx` server errors. Maps out redirect chains, broken internal/external links, and sitemap/canonical validity that waste crawl budget or block Google and AI indexers. 2. Competitor Benchmarking (Head-to-Head Reports): Compares a target URL directly against a competitor domain. Benchmarks metrics including content depth, technical health scores, overall error rates, and speed to highlight exact gaps where a competitor is winning. 3. Website Security and Server Audits: Combines on-page web scans (checking HTTP security headers, strict Content-Security-Policies, TLS configurations, and cookie flags) with deep server-side environment tests (`server_audit.py`). Generates comprehensive write-ups covering file permissions, sensitive config exposure, and DNS/email security posture. 4. Performance & Core Web Vitals: Evaluates rendering speed metrics like Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Time to First Byte (TTFB). ## See it for yourself Run the audits Gemini describes on your own site and compare. [See all audit tools](/seo-audit-platform.html) [What other AI tools say](/what-ai-says-about-aiwebpageseo.html) # 🛡 Website Security Audit A passive security scan of any public website HTTP security headers, TLS configuration, cookie flags, mixed content, server fingerprint, known CVEs via the NVD database, CMS detection, mail DNS records and security.txt, with no active payloads sent to your target. For domains you verify you own, an optional **active testing** tier confirms defences actually work live rate-limit, access-control, header-consistency and upload-filter checks. Public URLs only. Private/internal addresses are rejected. These send real (but bounded & polite) requests to your verified domain to confirm your defences actually work. **Every field below is optional** fill in the ones that apply to your site and leave the rest blank. The header-consistency check always runs; the others only run if you give them something to test. Not sure whether you have one? Leave it empty and that check is simply skipped nothing breaks. The AI fix prompt only covers changes to your site's own files (HTML, CSS and JavaScript), never server, hosting or DNS settings. Those are listed separately, and if you'd like them done for you, you can request a quote. Back up your site before letting any AI tool change it. Drop a button into your own site so your visitors can run this security audit on the page they’re viewing. It opens the audit here with the URL already filled in — they just press Run. Two versions: a simple link, or a smart one that always audits whichever page it sits on. Enter the page you want the button to audit, then copy the snippet into your CMS. Best for locked-down site builders (Wix, Squarespace, some WordPress) that strip scripts. Your button’s audit link updates below as you type. Paste this once. It automatically audits whichever page it’s on, so the same snippet works across your whole site. Needs a CMS that allows a small inline script (self-hosted WordPress, custom HTML blocks, raw-HTML embeds). - **TLS / SSL** live certificate validity, expiry and protocol version (via a real TLS handshake). *In plain terms: checks the padlock in the browser bar is real, current and using modern encryption not expired, misconfigured or faked.* - **Known CVEs** detected software versions matched against the NIST National Vulnerability Database (NVD). *In plain terms: if your site runs software with publicly known ways in, we flag it like checking whether your lock model is on a burglar's "easy to pick" list.* - **Cookie flags** Secure, HttpOnly and SameSite on every cookie. *In plain terms: makes sure the little files that keep you logged in can't be stolen or read by an attacker.* - **Mixed content** http:// resources loaded on an https:// page. *In plain terms: catches secure pages that quietly pull in insecure parts a locked front door with a window left open.* - **Forms & input handling** HTTPS form submission, CSRF-token presence and secure file-upload transport (passive; homepage forms only). *In plain terms: checks that anything you type or upload is sent securely and can't be hijacked by a malicious site.* - **Rate limiting & abuse protection** presence of RateLimit-* / Retry-After response headers (a passive signal; the active tier can confirm enforcement on domains you own). *In plain terms: whether your site slows down attackers trying thousands of password guesses and, if you own the domain, whether that limit actually kicks in.* - **Mail security DNS** SPF, DMARC and DKIM records that stop your domain being spoofed. *In plain terms: stops scammers sending emails that look like they came from you.* - **DNS security** CAA (restricts which CAs may issue your certs) and DNSSEC (cryptographically signed DNS). *In plain terms: controls who's allowed to issue certificates for your domain, and helps stop people being secretly redirected to a fake copy of your site.* - **Server fingerprint** version strings leaked in Server / X-Powered-By headers. *In plain terms: checks your server isn't announcing exactly what software and version it runs information that helps attackers target it.* - **CMS exposure** WordPress / Drupal / Joomla version disclosure. *In plain terms: makes sure your website builder isn't broadcasting its exact version, which tells attackers which known weaknesses to try.* - **Well-known files** robots.txt and security.txt (RFC 9116). *In plain terms: checks you publish the standard files that tell search engines what to index and give security researchers a way to report problems to you.* - **HTTP security headers** (CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, CORP) are evaluated against Mozilla's HTTP Observatory scoring model and the OWASP Secure Headers Project. - **TLS / SSL** is checked by a live handshake, following the Qualys SSL Labs and Mozilla TLS guidelines for protocol version, certificate validity and cipher strength with SSL Labs cited as the arbiter for cipher ordering. - **Known vulnerabilities** are matched against the NIST National Vulnerability Database (NVD). - **Content-Security-Policy** is analysed directive by directive, consistent with Google's CSP Evaluator and Mozilla's CSP guidance. - **Mail security** (SPF, DMARC, DKIM, MTA-STS, TLS-RPT, DANE) follows the relevant IETF RFCs. - **DNS** checks (CAA, DNSSEC) and **security.txt** (RFC 9116) follow their published specifications. Check whether web content is out of date. Enter a URL and we fetch the page, or paste content directly. We identify time-sensitive claims and check each against current Google results. Works on any site and any content. This check can take between 2 and 10 minutes — each claim is verified against live search results, so it runs as a thorough background pass rather than an instant scan. What each part of the audit checks, why it matters, and how to read the findings. If you've run a scan and want to understand a specific result, this covers the reasoning behind every check family. ### 1. What does a passive security audit actually check? A passive audit inspects everything a website reveals about itself through the ordinary requests a browser and a DNS resolver already make no intrusive probing. It reads your HTTP response headers to see which browser-level protections are set: Content-Security-Policy, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy and the cross-origin isolation headers. It performs a real TLS handshake to confirm your certificate is valid, unexpired and negotiating a modern protocol version. It examines every `Set-Cookie` header for the Secure, HttpOnly and SameSite flags. It looks for mixed content insecure `http://` resources loaded on a secure page. It fingerprints your server and any CMS from version strings they leak, then matches detected versions against the NIST National Vulnerability Database to flag known CVEs. On the DNS side it checks your mail-authentication records (SPF, DMARC, DKIM), your CAA record, and whether the zone is DNSSEC-signed. Finally it confirms you publish the expected well-known files, robots.txt and security.txt. Every one of these is read-only reconnaissance: the same traffic a normal visitor generates, plus public DNS lookups. Nothing is injected, nothing is brute-forced, and no endpoint is stressed. That's the deliberate boundary of the passive tier it tells you what your site advertises about its own posture, which is a surprising amount, without ever behaving like an attacker. To confirm that a defence actually *works* rather than merely being declared, you use the active tier on a domain you've verified you own. ### 2. What's the difference between passive and active testing? The passive scan reads; the active tier verifies. A passive check can tell you a `RateLimit` header is present, or that a CSP is declared, or that a page returns a 401 but reading a response can never prove the underlying control actually enforces anything. A site can advertise rate-limit headers and still let an attacker make ten thousand login attempts; it can serve a strict-looking CSP on the homepage and a broken one three pages deep. Active testing closes that gap by sending real, bounded requests and observing behaviour. It confirms that rate limiting genuinely throttles repeated requests, that pages you expect to require authentication aren't reachable anonymously, that your security headers are applied consistently across multiple pages rather than just the homepage, and that a file-upload endpoint rejects dangerous file types. Crucially, active testing is still not attacking. There are no exploit payloads, no injection strings, no attempts to break in the checks are polite, rate-limited, and designed to confirm a defence holds, not to defeat it. Because these requests genuinely hit your infrastructure, the active tier is gated behind proof of domain ownership: you add a DNS TXT record or a well-known file, the same verification standard Google Search Console and Let's Encrypt use, and only then can active checks run against that domain. This means you can never point active testing at a site you don't control. The passive scan runs on any public URL in seconds (typically well under a minute); the active tier is the deliberate, authorised second step for confirming your own defences do what they claim. ### 3. How is the security score calculated, and why might I score lower than on other tools? Most scanners total up points for everything you pass, which means a single dangerous failure gets diluted by a wall of green ticks you can "score 90" while your Content-Security-Policy is fundamentally broken. This audit does the opposite. You start at 100 and lose points weighted by how dangerous each specific failure actually is. Passing checks never inflate the score to hide a failure; one critical problem drops the grade hard regardless of how many minor checks pass, because in security a single unlocked door matters more than ten locked windows. The weighting reflects real risk: a broken CSP or an invalid TLS certificate costs far more than a missing robots.txt. A CSP that allows `unsafe-inline` or `unsafe-eval` in `script-src` is treated as seriously as having no CSP at all because it defeats CSP's core cross-site-scripting defence either way and carries a score-dominating penalty rather than counting as one tick among many. This is why you can score lower here than on a tool like Mozilla Observatory while being flagged for the same underlying issue: the finding is the same, but it's weighted by consequence rather than counted. The intent is a score you can trust as a genuine risk signal. A high number here means the things that would actually hurt you are handled, not that you accumulated enough small passes to bury a serious one. If your score dropped after a change, look for a high-severity failure that single item is doing most of the work, and fixing it will move the grade far more than clearing several minor warnings. ### 4. What are HTTP security headers and which ones matter most? HTTP security headers are instructions your server sends with every response that tell the browser how to behave defensively. They're one of the highest-leverage security controls available because they're enforced by the browser itself, on every visitor, without touching your application code. The audit checks the full set and weights them by impact. Content-Security-Policy is the most consequential: it restricts which sources of script, style and other resources the browser will load, and a well-formed CSP is the single strongest defence against cross-site scripting. Strict-Transport-Security (HSTS) forces browsers to use HTTPS and refuse to downgrade, defeating protocol-downgrade and SSL-stripping attacks; the audit also checks the policy is strong a long max-age with includeSubDomains because a weak HSTS policy barely sticks. X-Frame-Options (or a CSP frame-ancestors directive) prevents your pages being embedded in a malicious iframe, blocking clickjacking. X-Content-Type-Options stops browsers MIME-sniffing responses into an executable type. Referrer-Policy controls how much of your URL leaks to other sites. Permissions-Policy restricts access to sensitive browser features like camera, microphone and geolocation. The cross-origin isolation headers (CORP, and CORS behaviour) govern which other origins can embed or read your resources, mitigating a class of cross-origin data leaks. Of these, CSP and HSTS carry the most weight in the score because their absence or misconfiguration exposes the most serious attack classes. The others are important but lower-consequence. A common and dangerous mistake is declaring a CSP that still permits `unsafe-inline` scripts the header is present, but the protection it exists to provide is switched off, which is why the audit flags that case as severely as a missing policy. ### 5. What is a Content-Security-Policy and why does an "unsafe-inline" CSP fail? A Content-Security-Policy is a header that tells the browser exactly which sources it's allowed to load scripts, styles, images, fonts and other resources from. Its central purpose is to neutralise cross-site scripting: even if an attacker manages to inject markup into your page, a strict CSP means the browser refuses to execute any script that didn't come from an approved source. This is why CSP is considered the strongest browser-level XSS defence available. The catch is that CSP only works if it's actually restrictive. The directive `script-src 'unsafe-inline'` tells the browser to execute any inline script it finds on the page which is precisely the mechanism most XSS attacks rely on. An injected `
