A technical SEO audit checks the layer below content: whether search engines and AI engines can find, read and trust your pages at all. Google's documentation defines one piece of that map: "A sitemap is a file where you provide information about the pages, videos, and other files on your site, and the relationships between them." We test that file plus robots.txt, indexability, rendering and more, 164 graded checks in total, gate failures first.
If a page cannot be crawled, nothing else matters. Gate failures block your score until they are fixed, because that is how the engines treat them too.
Free Visibility Scan: whole site, up to 150 pages, no email. Full Report is a one-time $10.
Google-Extended, GPTBot, ClaudeBot, PerplexityBot and OAI-SearchBot are separate crawlers with their own robots.txt directives. Many sites block them unintentionally through wildcard Disallow rules that were never meant to apply. We check each bot individually. See fixing robots.txt AI blocks.
JSON-LD is now a precondition for AI citation eligibility, not just a nice-to-have for rich results. We validate your schema objects against the declared types, check for required properties and score answer-block readiness.
If your content only appears after JavaScript executes, crawlers may see an empty page. "Renders without JavaScript" is a scored Gate check. A fail here is a diagnosis, not a suggestion. See fixing JavaScript rendering.
Every check cites the official documentation it is grounded in. The reasoning is public in the learn library.

Technical SEO covers the infrastructure layer: can search engines and AI engines access and parse your pages at all? Content-level signals sit on top of this. If your technical layer is broken, content improvements will not save your rankings. Technical SEO is the prerequisite. The broader scans live at the SEO audit tool and website audit tool pages.
A Gate failure means a critical technical issue exists that blocks meaningful scoring of the rest of your site. It gates everything below it: there is no point optimizing title tags if Googlebot cannot reach the page. Gate failures are shown first, explained in plain English, with an effort estimate.
We check the HTML-source signals that shape Core Web Vitals on every scan. When real Chrome field data (CrUX) is available for your site, the report shows it; when a URL has no field data, we say so plainly rather than substituting a guess. The full breakdown lives on the Core Web Vitals page.
Yes. We check Googlebot, Bingbot and the major AI crawlers individually against your robots.txt, and we run a full 15-bot matrix that shows exactly which crawlers are permitted and which are blocked. The AI crawler optimization page goes deeper, and the AI search optimization hub covers the whole AI layer.
