Website SEO audit
40+ live checks with the exact fix for each problem, ordered by how much it matters. P0 means fix this week.
What the audit checks
The checker fetches the page the way a search engine would, follows redirects, and reads robots.txt, the XML sitemap and the HTML. It then runs checks in ten groups: indexability, on-page, content, structured data, performance, mobile, local and conversion, security, measurement and AI-search readiness.
Each finding has a severity. P0 problems stop a page from ranking at all, like an accidental noindex or a robots.txt that blocks the whole site. P1 problems hurt a lot, like a missing title or H1. P2 and P3 are improvements. The score weights problems by severity, so one P0 costs more than many small warnings.
What it can't tell you
Lab timing from one fetch is not real-user speed. For Core Web Vitals use field data from Chrome users (PageSpeed Insights or Search Console); Pro reports include it. The audit also can't see whether Google has indexed a page. Use Search Console's URL Inspection for that.
