An illustrated example of what you can make with this tool.

Check a page’s HTML

Inspect a public page that allows cross-origin reads, or paste its source. The score is the share of eight HTML checks passed.

Audit a page’s HTML for discoverability signals

Check the markup of a public page or a pasted HTML document. The eight checks give you a starting point for reviewing titles, headings, canonical and robots instructions, text, links and structured data.

Steps

  1. Use the public URL or view source

    Enter a public HTTPS page. If its server does not allow the browser to read it across origins, paste the page source instead. If the site renders its main content through JavaScript, also inspect the rendered page to see what the source omits.

  2. Read each finding before editing

    Check whether the canonical matches the URL you intend to share and whether robots directives agree with that intent. Compare the title, H1 and visible introduction. Review structured data for claims the page actually supports.

  3. Verify the change on the final page

    After editing, compare the HTML with the prior version. Use your site’s search reporting or URL inspection to check discovery, crawling and indexing. Measure impressions and clicks separately from this score.

File and export limits

Reads at most 512 KB with a 10-second fetch limit and follows browser cross-origin permissions. The audit examines supplied HTML without running its scripts. Its score does not measure indexing, rankings or citations.

Common questions

Why does a page load in a tab but fail here?

A browser can display a cross-origin page while preventing another site from reading its HTML. Paste the page source if you can access it.

Can a high score predict search traffic?

Use the score to review the supplied markup. Read first-party query and landing-page reports to measure actual search performance.
