The Technical SEO Audit: Exactly What We Check (And Fix)

A technical SEO audit is not a checklist of fixes — it is a diagnosis of whether Google can find, understand and trust your pages.

By CodeGen Global Team

Before any keyword work matters, Google has to be able to find your site, crawl it efficiently, index the right pages and understand what they are about. That is technical SEO, and it is the foundation everything else builds on.

Crawlability comes first. We check robots.txt, XML sitemaps, internal linking and for pages accidentally blocked from crawling. A page Google cannot crawl is invisible, no matter how good its content.

Then indexation. Duplicate content, thin pages, wrong canonical tags and pagination mistakes all dilute your index. The goal is to make sure only the pages you want to rank are taking up crawl budget.

Core Web Vitals matter for user experience and ranking. We measure LCP, INP and CLS, then hunt down the causes — oversized images, blocking JavaScript, slow servers. Speed work is usually the highest-leverage fix in an audit.

Structured data is how you qualify for rich results. We validate Organization, Product, FAQ and Article schema so Google can display your pages with more context.

The output of a good audit is not a list of twenty fixes. It is a prioritized set of changes, each with an estimated impact, so the team knows exactly what to do first.
