Questions about the audit
What does the SEO audit check?
More than 55 checks across seven areas: on-page SEO (titles, descriptions, headings, links, images), content, technical SEO (status codes, redirects, robots.txt, sitemaps, canonicals, hreflang), speed, security, social and structured data, and AI search readiness. Each issue includes a plain-English explanation and a fix.
Is it really free?
Yes. The audit and every tool are free to use without an account. Creating a free account lets you keep a history of your reports.
How is the SEO score calculated?
Each check has a weight based on how much it matters for search visibility. Passed checks earn full points, warnings earn half and errors earn none. The score is the weighted total out of 100, and each category gets its own score too.
Can I audit a competitor’s website?
Yes. You can audit any public website, and Site vs Site puts two or three sites side by side so you can see where you are ahead and where you are behind.
How is this different from Google Search Console?
Search Console shows how Google sees your site over time – indexing, queries and clicks – and only for sites you own. This audit gives an instant technical and on-page review of any page, with fixes. Use both together.
