SEO Audit Checklist
An SEO audit checklist covering crawlability, indexing, technical SEO, on-page content, links and reporting. Run it for a new client or every quarter.
- Typical schedule quarterly
- The checklist 5 sections, 26 items
- Variables
{{site}}
Use this checklist when you take over a new website, before a redesign or migration, or as a quarterly health check for a client on retainer. It walks through the order an experienced SEO would follow: first make sure search engines can crawl and index the site, then fix technical issues, then look at content and links. There is little point in rewriting titles on pages that are not indexed.
Who owns it
An SEO specialist or the marketer responsible for organic traffic owns the run. Many findings need a developer to fix, so the final step is a prioritised list of tickets, not just a report.
Common pitfalls
- Treating tool scores as the goal. Audit tools flag hundreds of minor issues. Rank findings by impact on important pages, not by the count of warnings.
- Auditing without data access. Without Search Console and analytics you are guessing. Get access before the audit starts.
- Ignoring templates. One faulty template can affect thousands of URLs. Group issues by page type.
- No baseline. Record traffic, indexed pages and rankings for key terms at the start, so you can show what changed later.
A scheduled quarterly run makes the audit a habit rather than a one-off project, and the finished runs show the client what was checked each quarter.

Frequently asked questions
How often should you do an SEO audit?
A full audit makes sense when you take over a site and before a redesign or migration. After that, a lighter quarterly check catches most problems before they cost traffic. Large sites that publish daily may need monthly checks of indexing and crawl errors.
What is the difference between a technical SEO audit and a content audit?
A technical audit checks whether search engines can crawl, render and index the site: robots.txt, sitemaps, canonicals, redirects and speed. A content audit checks whether the pages answer what people search for and whether they overlap. This checklist covers both, with technical checks first.
What tools do I need for an SEO audit?
At minimum you need Google Search Console, your analytics tool and a crawler. A backlink tool helps but is optional for small sites. The tools find issues; deciding which ones matter for the business is still the job of the person running the audit.
