Frequently asked questions

Does the audit cover the whole site?

This tool analyses one page. For a site-wide view, use the full SEO and GEO report, which crawls several pages and scores sixteen pillars.

Why is my score good when I have no visitors?

The score measures technical quality, not popularity. A technically perfect page with no inbound links and no sought-after content will get no traffic. Both dimensions are required.

Are images without alt really a problem?

Yes, for two reasons. They make the page inaccessible to screen reader users, which is a legal obligation in many contexts. And they deprive engines of a description of the visual content.

Is there a usage limit?

Thirty audits per minute per IP address. No account required, no daily cap.
