An SEO audit can produce a very long list of warnings. It does not follow that every warning deserves an urgent fix.
The useful question is: which issues prevent the right customers from finding, understanding or using your website? This SEO audit checklist puts those decisions in a sensible order. It works for an established company website whether you handle marketing in-house or work with an agency.
1. Confirm the pages you actually want Google to show
Start with a list of important URLs: the homepage, core services, relevant locations, useful articles and contact or enquiry pages. Each page should serve a distinct purpose.
In Google Search Console, review the Pages report and inspect a sample of those URLs. Check whether Google can crawl them and whether they are indexed. A page being submitted in a sitemap does not guarantee indexing.
Not every URL should appear in Google. Search results pages, thin tag archives, duplicate category archives and staging pages may reasonably be excluded. The goal is not to index everything; it is to make sure the *right* pages are eligible.
2. Check the sitemap, robots directives and canonicals
An XML sitemap helps search engines discover eligible URLs. Open yours in a browser and confirm it loads, lists current pages and does not contain old redirects or deleted content.
Next, check that important pages are not accidentally marked `noindex` or blocked from crawling. Review canonical URLs on key pages: they should normally point to the intended version of that page, not a duplicate or outdated address.
If a service page is missing from search, these technical checks should happen before anybody rewrites the headline for the fifth time.
3. Find broken pages and unnecessary redirects
A website audit tool can identify internal links leading to 404 pages, broken images and redirect chains. Prioritise problems affecting your main navigation, service pages, contact paths and highly visited articles.
A redirect is not automatically bad. Permanent redirects are useful when a page moves. However, internal links should ideally point straight to the final destination rather than sending visitors through multiple hops.
Do not redirect every removed page to the homepage. If there is no relevant replacement, a genuine 404 can be more appropriate than a misleading destination.
4. Match each important page to one clear search intent
Ask what the visitor expects to achieve. Someone searching for a service provider usually needs evidence, scope, location and a clear enquiry route. Someone searching for a how-to answer needs a useful explanation.
Review the page title, main H1, opening paragraph and section headings. They should describe the same subject naturally. Avoid making several pages compete for the identical primary topic.
For example, a service page can target an agency-related phrase such as “SEO services”, while a supporting article tackles a narrower informational query such as “SEO audit checklist”. The pages help each other instead of repeating the same sales pitch.
5. Review internal links and page structure
Can someone reach the important service pages from the menu? Do related articles link back to the right service? Are link labels descriptive enough to make sense outside their surrounding paragraph?
Useful internal links support navigation and help search engines understand relationships between pages. Add them where they help the reader; avoid filling every paragraph with the same anchor text.
Check that headings follow a logical hierarchy and that long pages are broken into understandable sections. Good SEO and good user experience often ask for the same thing: clarity.
6. Test real mobile usability and performance
Run the key pages through PageSpeed Insights and inspect Core Web Vitals where enough field data exists. Then use an actual phone.
Can you read the headline without zooming? Do images cover the text? Does the menu work? Is the contact form easy to complete? Page speed matters, but an impressive synthetic score is not a substitute for a working customer journey.
Optimisation settings should be tested carefully. CSS and JavaScript changes can improve load time or break a layout, particularly on websites that rely on page builders and several plugins.
7. Check that enquiries can be measured
Organic traffic is useful context. Qualified enquiries are closer to the business outcome.
Check that analytics and Search Console are connected to the correct property. Test important contact forms and confirm whether successful submissions are measured. If your site receives calls or bookings, decide how those will be recorded. Avoid counting every button click as if a genuine lead had been received.
8. Turn the audit into a priority list
Sort findings into three groups:
- Fix first: important pages blocked from indexing, broken enquiry paths, critical security problems and serious mobile usability failures.
- Fix next: poor titles, weak internal linking, unnecessary redirects, missing useful content and manageable performance issues.
- Monitor or accept: low-impact notices, intentionally noindexed archives and items with no meaningful visitor consequence.
Keep a dated baseline, note each change and measure what happened afterwards. A high health score is encouraging; relevant search visibility and working enquiries matter more.
