Technical Website Audit
A systematic review of a site's crawlability, indexability, performance, security, and technical SEO setup to find issues that limit search visibility or user experience.
If you have ever run a crawl, fixed every error, and seen no ranking change, you already know an audit without prioritisation is just a list.
Key points
- Audit your site periodically, not once — CMS updates and regressions introduce new issues.
- Prioritise fixes by impact on crawlability, indexation, and revenue, not by error count.
- Include speed, mobile usability, and security checks — not just crawl errors.
- Audit the live, crawled environment, not a staging site or cached version.
- Update your checklist as Google changes crawling, rendering, and Core Web Vitals guidance.
A crawl that found 400 errors but changed nothing
An e-commerce site ran a technical audit and found 400 broken links, 50 duplicate title tags, and a missing XML sitemap. The team fixed every error in two weeks. Organic traffic did not move. The real issue was that the product pages took eight seconds to load on mobile and failed Core Web Vitals — something the initial crawl had not prioritised. A second audit, focused on speed and mobile usability, led to a 30% increase in indexed pages and a measurable traffic lift.
Three things a technical audit is not
- Not a content review It checks crawlability and indexability, not whether your copy is persuasive or your headings match search intent. A separate content review handles that.
- Not a one-time task Site changes, CMS updates, and technical regressions introduce new issues over time, so audits need repeating periodically to catch what breaks.
- Not a ranking guarantee Fixing technical issues removes barriers to visibility but does not guarantee higher rankings — that also depends on content and authority.
Three ways it goes wrong
- Auditing the wrong environment Running a crawl on a staging site or cached version can miss robots.txt blocks or show misleading performance data, wasting your effort.
- Ignoring mobile usability Poor mobile experiences hurt both users and search performance, yet some audits still focus only on desktop crawl errors. Use a seo duplicate content checker or open graph tester sparingly.
- Fixing without prioritising Fixing every 404 before addressing slow Core Web Vitals wastes effort — impact on crawlability and revenue should guide the order. Tools for seo audit help you sort by severity.
