A thorough audit usually spans four broad areas: technical (crawlability, indexing status, site speed, Core Web Vitals, mobile usability), on-page (title tags, headings, content quality and depth, internal linking), content (identifying thin, outdated, or cannibalizing pages), and off-page (backlink profile health, referring domain quality, any manual actions). Audits are typically triggered either on a regular schedule (annually or after major periods of growth) or reactively, in response to a traffic drop, a site migration, or before a major content strategy reset — the reactive kind usually needs to move faster and focus narrowly on what changed around the time of the drop rather than a full, slow, comprehensive review. The output of an audit should be a prioritized list of specific, actionable fixes, not just a diagnostic report, since an audit that doesn't translate into implemented changes has limited practical value.
Example
A pre-migration SEO audit catches 40 pages with duplicate content issues and 15 with broken internal links before a site relaunch, preventing those problems from carrying over into the new site structure.
