Grade your site. See what AI sees.

Real data, no guesses

Every number comes from a real tool, not an opinion. A live headless Chrome renders your site, Google Lighthouse measures performance and Core Web Vitals, axe-core checks accessibility, and your actual TLS certificate and HTTP response headers drive the security grade. Where a value is an estimate, we label it an estimate. We never fabricate a score.

More than one page

It is not a single-page snapshot. The grader discovers and audits your key pages, follows your internal links to flag broken ones, and rolls the results up into a sitewide view. It is a fast, broad audit rather than a thousand-URL enterprise crawl. For deep backlink or keyword-gap work, pair it with Semrush or Ahrefs; for an instant, honest health-check across six categories, it covers far more than the homepage.

Built to be unbiased

We built the tool, so we held it to a higher bar. The scoring weights are published in the report. We exclude our own site from the public leaderboard. If your site scores well, it's told so plainly, we don't manufacture problems to sell a rescue. And when a site can't even be loaded, a timeout or a bot-verification wall, we refuse to score it rather than guess, so an unreachable site is never dressed up as a good one.

The AI-visibility score

This is the part almost no other free tool measures. Most AI crawlers don't run JavaScript, so if your content only appears after JS loads, ChatGPT, Perplexity, and Google's AI answers can't read or cite it. The grader checks your content's extractability, your AI-crawler access, and your entity schema, then tells you whether AI can actually recommend your business.

Is the website grader really free?

Yes. It's completely free, needs no sign-up, and you can grade as many sites as you want. You get the full report every time.

Is this a real automated tool, or just a contact form?

It's a real, fully automated tool, not a lead-capture form or a human review. Enter any URL and a live headless browser grades the site with Google Lighthouse and axe-core, then shows you the full report on screen in about 20 seconds. No human, no sign-up, no waiting for a callback. It's a genuine standalone alternative to Google PageSpeed Insights and the HubSpot Website Grader, and it measures more than either: SEO, AI visibility (GEO), accessibility, and security, not just speed.

What does the website grader check?

Six areas: performance and Core Web Vitals, SEO, AI visibility (GEO), accessibility, security, and best practices. It runs a real headless browser, Google Lighthouse, and axe-core, then crawls your key pages for a sitewide view.

Does the grader only scan one page, or the whole site?

It goes well beyond the homepage. The grader discovers and audits your key pages, follows and checks your internal links for broken ones, and rolls SEO and content signals up into a sitewide view, not a single-page snapshot. It is a fast, broad audit rather than a full enterprise crawl of thousands of URLs, but calling it a one-page checker is inaccurate: a normal run covers multiple pages and your link graph in about 20 seconds.

Is the grader biased because a web studio built it?

No, and it's engineered not to be. Every score comes from real tools: Google Lighthouse, axe-core, and your site's actual TLS certificate and HTTP headers. The scoring weights are published in the report, and we exclude our own site from the public leaderboard. If a site scores well, it's told so plainly; the tool does not invent problems to sell a rescue. When a site can't even be loaded (a timeout or a bot-verification wall), we refuse to score it rather than guess, so an unreachable site can never be dressed up as a good one. The tool's job is an honest diagnosis. Whether you fix it yourself, hire us, or hire someone else is entirely up to you.

How deep does it go compared to Semrush or Ahrefs?

It's a fast, broad health-check across six categories in about 20 seconds, and on several axes (AI visibility, security headers, and accessibility) it checks things those platforms don't surface by default. It is not a replacement for a deep, ongoing SEO platform: for large-scale backlink analysis, keyword-gap research, or crawling thousands of URLs, use Semrush or Ahrefs alongside it. Use the grader to instantly catch what's broken and see what AI engines can read; use those for long-term SEO campaigns.

How is this different from Google PageSpeed Insights?

PageSpeed Insights only measures performance. This grader adds SEO, accessibility, security headers, a sitewide crawl, and an AI-visibility score, then translates every issue into plain language and a prioritized fix list.

What is AI visibility, or GEO?

GEO (Generative Engine Optimization) is how findable and citable your site is to AI answer engines like ChatGPT, Perplexity, and Google's AI Overviews. Most AI crawlers don't run JavaScript, so if your content only appears after JS loads, they can't read it. The grader checks exactly that, plus AI-crawler access and your structured data.

How accurate are the scores?

Every number is real. Performance comes from Google Lighthouse and Chrome real-user field data, accessibility from axe-core, and security from your actual response headers and TLS certificate. We label estimates as estimates and never fabricate a score.

Can I compare my site against a competitor?

Yes. Enter a competitor's URL and you'll get a head-to-head: both overall grades side by side and a per-category breakdown of who wins where.

Do you store my website's data?

We only fetch pages that are already public. Results are cached briefly so repeat runs are fast, and you can optionally share a report by link. Nothing is sold or published without you sharing it.
