How to check the SEO of a page?

14 June 2026 · By John Carlsson

Check the page loads quickly and works on a phone, then view its source to confirm it has a unique title, a meta description, one H1 heading, a canonical tag pointing to itself, and alt text on its images. Free tools such as Lighthouse in Chrome check these in one report.

To check the SEO of a page, start with technical fundamentals: fast loading, mobile-friendly, valid SSL. Review the page title and meta description for uniqueness and keyword relevance. Check heading hierarchy. Inspect content for keyword relevance, readability, and adequate length. Look at internal linking, image alt text, and canonical tags. Online SEO auditing tools flag broken links, duplicate content, missing metadata, and poor Core Web Vitals.

A systematic page SEO checklist

To check the SEO of a page reliably, cover these elements in sequence: (1) Load the page on a mobile device and confirm it loads in under 3 seconds — if it doesn't, that's the first priority regardless of everything else.

(2) View the page source (right-click → View Page Source) and search for 'title' to confirm the title tag is present, unique, and under 60 characters. (3) Search for 'description' to confirm the meta description is present and under 160 characters. (4) Check that there's exactly one H1 heading. (5) Confirm the page has a canonical tag pointing to itself (not another URL). (6) Check that images have alt attributes.

Using free tools to check the SEO of a page without technical knowledge

Several free tools allow you to check a page's SEO by simply entering its URL. They return a scored report covering the most common technical and on-page issues. Chrome's built-in Lighthouse tool (accessible via F12 → Lighthouse tab) is particularly useful because it comes from Google itself and evaluates performance, accessibility, and SEO simultaneously, giving you a direct view of how a Googlebot-equivalent sees your page. Search Console's URL Inspection tool shows you exactly how Google has indexed the specific page, what its canonical is, and when it was last crawled.

The element most site owners overlook in a page SEO check

Most page SEO checklists focus on technical elements and metadata, but the most commonly overlooked element is search intent alignment — whether the page's content actually matches what someone searching for the target keyword genuinely wants to find. A page can be technically perfect in every way but still rank poorly if it answers the wrong question, or answers the right question for a different level of searcher than the people actually performing the search. Checking this means searching your target keyword yourself and honestly comparing your page to what's already ranking — not just checking boxes on a technical list.

Why is search intent important when checking page SEO?

Search intent alignment is the element most often overlooked in a page SEO check. It means asking whether the page's content actually matches what someone searching for the target keyword wants to find. A page can be technically perfect in every way yet still rank poorly if it answers the wrong question, or answers the right question for a different level of searcher than the people actually searching. To check it, search your target keyword yourself and honestly compare your page with what already ranks, rather than simply ticking boxes on a technical list.
