# What does an advanced Technical SEO audit look like?

> An advanced audit begins with the website's architecture and business model, not with a crawler's warning list.

A mature audit examines:

- URL inventory

- crawl behavior

- server responses

- rendering

- indexation

- canonicalization

- internal linking

- XML sitemaps

- robots.txt

- JavaScript

- structured data

- internationalization

- performance

- migrations and change history

- business impact

The output should explain **what is happening, why it matters, what should change, how to implement it and how to validate it**.
