Paste a page and get two things instantly: valid JSON-LD schema markup — for up to 1,000 items on a page — and an AEO-ready llms.txt file that gives answer engines a clean summary of your site. Then a free schema debugger checks the existing schema on any page, flagging what's invalid, incomplete or missing. 100 free points for new accounts · PAYG from £4.99 or subscribe from £14.99/mo · Credits never expire ## Search engines and AI can't rank what they can't understand Schema markup is the code that gives Google and AI answer engines machine-readable clues about what your page represents. Without it, they have to infer more of your page's meaning from its content and structure. With it, you can become eligible for rich results and give search and AI systems clearer information to work with. ### The debugger shows what's broken Most sites have missing, invalid or incomplete schema and never know. The free debugger scans your page, tells you exactly what's wrong, and gives you the fix — before it costs you rankings. ### The generator writes it for you No hand-coding JSON-LD. Paste a URL and get standards-valid schema built from your real page content, ready to paste into your head — for the most appropriate detected type. ### Built for real catalogues A shop with 800 products or a venue with 200 events? Other tools tap out after a handful. This one builds schema for up to 1,000 items in a single run. ## Detected as one type? Switch it to another. The generator auto-detects what a page is and builds the right schema for it. But you're not locked in. Say a page comes in as a plain WebPage — if it's really your shopfront, switch the type to LocalBusiness and it rebuilds the schema for that instead, pulling the right fields. Detected as an Article but it's a product? Switch to Product. A generic page that's really an Event, FAQPage or Recipe? Pick it from the list and the schema is regenerated to match — from your real page content, always valid. ## Find every schema problem on your page — free A schema debugger reads the structured data on your page the way Google does, then flags what's missing or invalid. It's the fastest way to see why your rich results aren't showing — and it costs nothing to run. - Detects missing, invalid or duplicate schema - Checks the fields Google needs for rich results - Shows how AI answer engines read your page - Tells you exactly what to add or fix ## Be the answer, not just a result Answer engines don't show ten links — they read your page, decide what it means, and quote it. That's where llms.txt comes in: a plain-text file at your site root that hands AI a clean, quotable summary of your site and its key pages. Our generator writes it for you, alongside your schema, so ChatGPT, Perplexity and Google AI understand exactly what you do. - Generated automatically from your real page content - Structured the way AI models parse best - Highlights your key pages and what they cover - Upload once to your root — like robots.txt ## Not just llms.txt — a collection of emerging AI discovery files The generator produces the full set of AI discovery files in one run: llms.txt, llms-full.txt and llms.md, plus the emerging ai.txt, identity.json, agents.md and ai-catalog.json. That sets you up for how AI crawlers and agents will find sites next, not just today. ### ai.txt The Spawning AI purpose-based permissions standard. Declares how AI may use your content. ### identity.json Bing specifically fetches identity.json to understand who a site belongs to. Generated for you, ready to upload. ### ai-catalog.json Google and 10 others shipped ai-catalog.json support in June 2026. The generator writes it and tells you exactly where it goes. ## One tool, the whole schema.org library Auto-detected or hand-picked, the generator builds valid markup for over ninety types — from content and commerce to every kind of local business. ### Content & media Article · NewsArticle · BlogPosting · FAQPage · HowTo · Recipe · Review · Course · VideoObject · DiscussionForumPosting · Event · JobPosting ### Core & commerce Organization · Person · Product · SoftwareApplication · WebPage · WebSite · BreadcrumbList · ItemList · LocalBusiness ### Food & drink Restaurant · Bakery · Bar / Pub · Brewery · Café / Coffee Shop · Distillery · Fast Food · Ice Cream Shop · Winery · Food Establishment ### Shops & retail Clothing · Electronics · Furniture · Grocery · Hardware · Jewellery · Book · Toy · Pet · Shoe · Mobile Phone · Computer · Garden · Sporting Goods & more ### Professional & local services Professional Service · Legal · Financial · Estate Agent · Dentist · Medical / Healthcare · Health & Beauty · Automotive · Home & Construction · Travel Agency ### Community & public Library · Government Office · Emergency Service · Employment Agency · Childcare · Animal Shelter · Self Storage · Recycling Centre · Tourist Information & more ## URL in, schema out — in minutes ### Paste your URL The tool fetches your live page — content, headings and any schema already there. ### Generate or debug Build JSON-LD schema for up to 1,000 items, generate your site llms.txt, or run the free debugger on existing schema. ### Copy & publish Paste the JSON-LD into your head, upload llms.txt to your root to provide AI systems with a concise, machine-readable summary of your site. ## Frequently asked questions Straight answers about what the tools do, what they cost, and how the files work.

New accounts get 100 free points, and credits never expire. llms.txt is a plain-text file placed at your site root that gives AI models a clean, structured summary of your site and its key pages. The generator produces it, along with related AI discovery files, from your real page content so answer engines can understand what you do. Over 90 schema.org types, auto-detected from your page with a manual override if you want to change the type. Coverage spans content, commerce and every kind of local business. Yes — aiwebpageseo generates valid JSON-LD schema markup automatically from any public URL, with no coding required. It detects the correct schema.org type, builds the markup, and handles up to 1,000 items — such as products, events or FAQs — in a single run. Yes — the free schema debugger checks the JSON-LD already on any page, flags what's missing, invalid or incomplete, and shows the fix needed to correct it. aiwebpageseo focuses specifically on Answer Engine Optimisation (AEO): generating schema markup and llms.txt files so AI systems can understand and cite a page correctly, alongside a free schema debugger to catch errors that would otherwise stop a page being understood. Yes — aiwebpageseo generates llms.txt and related AI discovery files directly from a site's real page content, giving AI models a clean, structured summary of what the site covers. This depends on your needs — options range from free single-page generators to enterprise platforms. aiwebpageseo generates schema for over 90 schema.org types automatically from a URL, handles up to 1,000 items per run, and includes a free schema debugger, aimed at working without manual field-filling. Accuracy largely comes down to how a tool determines page type and required fields — automatic detection from real page content tends to produce fewer errors than manual form entry, since it doesn't depend on the user knowing every required property. aiwebpageseo auto-detects the correct schema.org type from a URL and allows a manual override, combined with a free debugger to catch anything the generation step misses. Agencies vary in tooling depending on client size and whether schema needs managing at scale or per page. For solo operators and smaller sites that need structured data generated and checked without a manual, per-field workflow, aiwebpageseo combines automatic schema generation, a free debugger and llms.txt generation in one tool. Manual form-based generators require entering details per page by hand; enterprise platforms are typically built for managing schema at scale across large teams. aiwebpageseo generates schema automatically by reading the actual content at a URL rather than manual form entry, covers over 90 schema.org types, and adds a free schema debugger and llms.txt generation in the same tool. There's no single tool the whole industry standardises on — choices vary by budget, CMS and whether schema needs generating at scale or per page. aiwebpageseo is built for automatic, URL-based generation across a wide range of schema types plus free error debugging, suited to sites that don't want to fill in fields by hand. The space spans free single-purpose generators, CMS plugins, enterprise-scale platforms, and validator tools for checking existing markup. aiwebpageseo sits in the automatic-generation category, combining schema generation, a free debugger and llms.txt/AEO file generation in one tool rather than requiring separate tools for each step. ## Answer Engine Optimisation: how to be quoted by AI, not just ranked By John Carlsson, Founder of AIWebPageSEO · Published 5 May 2026 · Updated 17 July 2026 Search used to end with a list of blue links. Increasingly it ends with an answer. ChatGPT, Perplexity, Google AI Overviews and Microsoft Copilot read pages, decide what they mean, and hand the user a summary — often quoting a handful of sources directly. Answer Engine Optimisation (AEO) is the practice of making your pages easy for those systems to read, understand and cite. It sits alongside traditional SEO rather than replacing it: SEO helps you rank, AEO helps you get quoted. ### Why AEO is not the same as SEO Classic SEO optimises for a ranking position in a list. AEO optimises for something different: being the source an AI model paraphrases or names when it answers a question. That changes what matters. An answer engine does not need your page to win a keyword race. It needs to parse your page confidently, extract a clear answer, and trust the source enough to repeat it. Pages that are cleanly structured, factually specific and unambiguous tend to be favoured, because they are cheaper for a model to interpret correctly. ### What makes a page quotable Three things do most of the work. First, structured data. JSON-LD schema tells an engine exactly what a page is — a product, a local business, an FAQ, a how-to — instead of leaving it to guess from raw HTML. Second, answer-first writing: lead each section with a direct, self-contained answer of roughly 40 to 60 words, then expand. Models extract those leading statements well. Third, trust signals: a named author with real expertise, publication and updated dates, cited sources, and accurate claims. Answer engines are conservative about which sources they name, and these signals reduce their risk. ### The role of schema markup Schema markup is the layer that removes ambiguity. Without it, an engine infers meaning from headings, layout and text, and it can get that wrong. With valid JSON-LD in place, the page states its own type and key facts — who published it, what it sells, what it costs, what questions it answers. That makes accurate schema a potentially high-leverage improvement, particularly where the page represents a well-defined entity or content type: it converts a page an engine has to interpret into one that describes itself. The catch is that the markup must match the visible content. Declaring an FAQ or an article that is not actually on the page erodes trust rather than building it. ### llms.txt and the emerging AI discovery files A newer set of conventions guides AI crawlers at the site level. An llms.txt file sits at your domain root and gives models a clean, plain-text index of your site and its most important pages. Think of it as a table of contents written for a machine with a small context window. Related files such as ai.txt and identity.json declare usage preferences and identity. None of these are guaranteed to be read by every AI provider today, so they are best treated as low-cost, forward-looking additions rather than a ranking factor. The honest position is to publish accurate, consistent files now, in case they are used, without overselling what they do. ### A practical AEO checklist - Confirm AI crawlers can reach your pages — check robots.txt allows OAI-SearchBot (ChatGPT search), PerplexityBot, ClaudeBot and Bingbot. - Add valid JSON-LD schema for the real type of each page, and keep it matched to visible content. - Lead sections with a direct answer, then provide detail and cite named sources. - Show authorship, publication and updated dates, and keep content current. - Publish an llms.txt at your root and keep it in step with your site as it changes. Done together, these steps make a page that an answer engine can read without effort, trust without hesitation, and cite by name. That is the whole goal of AEO: not simply to appear in results, but to become the answer. ## llms.txt and schema markup: a map and a translator for your site By John Carlsson, Founder of AIWebPageSEO · Published 12 May 2026 · Updated 17 July 2026 If you want AI systems to understand your website, two files do most of the heavy lifting, and they solve two different problems. Schema markup is a translator: on any single page, it states in a machine-readable format exactly what that page is and what it contains. An llms.txt file is a map: at the level of the whole site, it hands an AI a clean, curated list of your most important pages. Used together, they let a model understand both the individual page in front of it and how that page fits into everything else you publish. ### Schema markup: describing a single page Schema markup, written as JSON-LD, sits in a page’s code and declares its meaning. It says “this is a product with this price”, “this is a local business with these opening hours”, or “this is an FAQ with these questions and answers”. Without it, a search engine or answer engine has to infer meaning from headings, layout and prose, and it can guess wrong. With it, the page describes itself, which is why accurate schema can be a high-impact change for AI visibility, particularly for well-defined entity or content types. The one rule that matters most: the markup must reflect what is actually on the page. Declaring a type or content that is not really there does more harm than good. ### llms.txt: describing the whole site llms.txt is a plain-text file placed at your domain root, for example at yoursite.com/llms.txt. Schema describes one page. llms.txt describes the site as a whole: a short summary of what you do, followed by a curated list of your key pages with one-line descriptions. Modern web pages are heavy with navigation, scripts and visual chrome, and models have limited context windows. llms.txt cuts through that by giving the model a short, plain index of the pages worth reading, in the order of priority you choose. It is a table of contents written for a machine rather than a human. ### Why they work better together The two files reinforce each other. llms.txt points an AI to the pages that matter; schema then lets it read each of those pages without ambiguity. A model that arrives via llms.txt, and finds well-formed schema on every page it visits, can build an accurate picture of your business quickly and cheaply. That is exactly when answer engines are most willing to cite a source. Neither file guarantees that any given AI provider will read it today. The honest approach is to publish both accurately and keep them consistent — low-cost, forward-looking foundations rather than a guaranteed ranking lever. ### Generating and maintaining them Both files can be produced from your real page content rather than written by hand. A generator reads a live URL, builds standards-valid JSON-LD for the correct page type, and produces an llms.txt summarising the site — along with related discovery files such as ai.txt and identity.json. The work does not end at generation. Schema should be updated whenever a page’s content changes. Refresh llms.txt whenever you add major content or change focus, so the map and the translations always match the territory. ### Where to start - Run a schema debugger on your key pages to see what is missing, invalid or incomplete. - Generate valid JSON-LD for the true type of each page and paste it into the head. - Create an llms.txt that summarises your site and lists your most important pages with descriptions. - Keep both in step with your content, and check that your schema always matches what visitors actually see. Give an AI a translator for each page and a map of the whole site. You remove most of the guesswork between your content and the answer a model gives about you. That is the practical core of getting understood, and cited, by AI. Ask a question about the platform or leave feedback. Comments are reviewed before appearing.
