How the free SEO audit works
Built for business owners, not SEO experts — everything is explained in plain English.
Paste your address
Enter any page URL — your home page is the best place to start. Add a target keyword if you have one in mind.
We run 50+ checks
We fetch your page like Google does, measure speed with Google's own engine, and test everything from titles to AI-crawler access.
Fix with confidence
You get letter grades, a prioritized fix list with copy-paste code, AI rewrites, and a one-click prompt for your AI coding assistant.
Everything the SEO analyzer checks
Seven categories, 50+ individual checks — the same ground paid tools cover, plus AI-readiness checks most of them don't have yet.
On-Page SEO
Title tags, meta descriptions, headings, content depth, keywords, canonical tags — the fundamentals Google reads first.
Technical SEO
robots.txt, XML sitemap, SSL, redirects, HTTP/2, mixed content and the security headers that signal a well-run site.
Performance
Real Google Lighthouse scores and Core Web Vitals for mobile and desktop — the official speed ranking signals.
Mobile Usability
Viewport setup, readable font sizes and tap targets — how your site actually feels on the phone in your customer's hand.
Social Sharing
Open Graph and X card tags that turn shared links into rich preview cards instead of bare grey URLs.
AI Readiness (GEO)
Can ChatGPT, Claude, Perplexity and Google AI read and cite you? AI-crawler access, identity schema, llms.txt and more.
Link Health
Internal link structure, broken-link detection, and your domain's authority score from the open web graph.
AI-Written Fixes
Gemini rewrites your title and description, builds your action plan, and we generate a fix-it prompt for your AI coding tool.
Why run an SEO audit?
Most websites lose traffic to problems the owner can't see: a title tag that's too short to rank, a page that takes five seconds to load on a phone, a robots.txt file quietly blocking crawlers, or share links that unfurl into a bare grey URL. Each one is invisible when you look at your own site — and each one costs you visitors every day.
An SEO audit finds these problems in seconds and — more importantly — tells you which ones matter. Not every issue is worth your time; a missing meta description on your homepage is urgent, an uncompressed image on a rarely visited page isn't. That's why every issue in your report carries a priority, a plain-English explanation of what it costs you, and exact fix instructions.
And search is changing: a growing share of discovery now happens inside ChatGPT, Claude, Perplexity and Google's AI answers. If AI crawlers can't read your site — or can't tell who you are — you're invisible in the places your next customers increasingly ask first. Our AI-readiness section grades exactly that, before your competitors have even heard of it.
