Technical SEO
A technical SEO check confirms four things in order: that search engines can reach your pages, that they render with content present, that duplicates are resolved to one address, and that the structure describes what each page is.
In order
Confirm the robots file does not block directories that matter, that important pages return a 200 rather than a redirect chain, that the sitemap lists only canonical, indexable URLs, and that no staging noindex survived launch. A single stale directive here can remove an entire section from eligibility.
Fetch a page as a crawler would and confirm the main content is present in the initial HTML rather than appearing only after JavaScript executes. This is the check most often skipped and the one most likely to explain why a modern site underperforms with AI crawlers specifically.
Every page should declare a self-referencing canonical, and the canonical, the internal links and the sitemap entry should all name the same URL. Check that parameters, trailing slashes and case variations do not serve the same content at different addresses without a declared preference.
One H1 per page, a heading order that does not skip levels, structured data that validates and describes content actually on the page, image dimensions set to prevent layout shift, and Core Web Vitals assessed on field data rather than a laboratory score.
Access first, then rendering, then duplication, then structure. Each stage can invalidate the next: there is no value in checking headings on a page a crawler cannot reach or render.
Fully once or twice a year, and after any launch, migration or platform change. Access and indexing should be monitored continuously, because those failures are silent and expensive.
