Compare sitesCalling the scanner an SEO audit is not the most useful framing. A better one: it measures how legible your site is to the systems that decide whether a human ever finds it in 2026. That still includes Google. It increasingly includes Claude(opens in new tab), ChatGPT, Perplexity, and every general-purpose agent that routes users through conversation before they ever type a query into a search box.
The checks break into four categories. Fifty-four cover AI visibility, which is the newest and heaviest-weighted category in the 2026 calibration. Thirty-one cover classical technical search engine optimization, which is what agencies have been doing for two decades. Thirteen cover technical infrastructure: headers, protocols, and response behavior. The rest cover accessibility, performance, content quality, compliance, and image optimization. Every check has a weight between one and eleven, and a severity level that determines whether a failure counts as critical, high, medium, or low.
The overall score is the weighted average of every check, scaled to a hundred and converted to a letter grade. Anything below seventy is Grade D, which is what most sites run at by default because they were built before AI visibility became a first-class optimization target. Grade B is eighty or above. Grade A is ninety or above. The second number is the AI Visibility score, which isolates the fifty-four checks most predictive of citation behavior by large language models. The third is the GEO Readiness score, which measures content structure and extraction signals for generative engine optimization. Sites that optimize for classical SEO but ignore AI visibility tend to score well on the overall but fail the other two.
Every report ends with a prioritized action plan. The top of the list is always the highest-weight failure with the lowest fix effort — what the scanner calls a quick win. A typical quick win might be: add two outbound links to authoritative sources, which takes about five minutes and raises your weighted score by two points. A typical medium-effort fix might be: rewrite page titles to the thirty-five-to-sixty-five character range, which takes an hour and fixes three checks at once. The long work is content structure, which the scanner cannot do for you but can tell you exactly what to add.
Most teams waste distribution effort on pages that are not ready. The scanner exists so that effort can go where it will actually land.
