A technical SEO audit checks whether search engines can discover, crawl, understand and index the important pages on a website. The goal is not to collect warnings. It is to find problems that affect valuable pages and prioritize fixes by business impact.
Start with service pages, product categories, important landing pages and articles that support business goals. Then expand the review to the rest of the site.
1. Confirm which pages should be indexed
Use Google Search Console’s URL Inspection tool on important pages. Record the indexing status, last crawl, user-declared canonical and Google-selected canonical when available. A page can load in a browser but still be excluded from search.
Check for accidental noindex directives.
Confirm canonical tags point to the preferred URL.
Check redirects, robots.txt rules and server errors.
Separate valuable pages from utility pages that should not appear in search.
Do not try to index every URL. Account pages, internal search results and many filtered combinations may not deserve search visibility.
2. Review robots.txt and XML sitemaps
Make sure robots.txt does not block important content or resources needed to render pages. The XML sitemap should list preferred canonical URLs, not redirects, error pages or noindex pages. A sitemap helps discovery but does not guarantee indexing. See Google’s sitemap documentation.
3. Test status codes and redirects
Important pages should return the correct HTTP status. Find internal links to 404 pages, redirect chains and misleading soft 404s. Redirect permanently moved pages to the closest relevant replacement; do not send every retired URL to the homepage.
4. Review site structure and internal links
Important pages should be reachable through clear navigation and contextual links. Check whether service pages receive links from relevant articles, whether related guides link to one another and whether any valuable pages are effectively orphaned. Use descriptive anchor text that helps readers understand the destination.
5. Test mobile usability and performance
Review pages on a real mobile viewport. Look for horizontal overflow, small text, overlapping elements, difficult forms and buttons that are hard to tap. Use PageSpeed Insights and field data where available to investigate slow main content, delayed interactions and unexpected layout shifts.
6. Inspect titles, headings and structured data
Important pages need descriptive titles, a clear main heading and content that matches the page’s purpose. Find duplicated titles, empty metadata and structured data that does not match visible content. Never add fabricated reviews, ratings or claims to markup.
7. Verify analytics and lead tracking
Test form submissions, calls, bookings or purchases and confirm events are recorded correctly. Duplicate events can exaggerate performance; missing events can hide real results. Re-test after major site updates.
Document the affected URLs, evidence, likely impact, owner and verification method. A noindex directive on a primary service page is more urgent than a minor metadata issue on a low-value archive.
Audit checklist
Important pages are crawlable and eligible for indexing.
Canonicals and sitemap URLs are consistent.
Redirects and status codes are correct.
Internal links support important topics and services.
Mobile layouts, performance and forms work.
Metadata, structured data and analytics are accurate.
A practical audit workflow
Choose a representative set of URLs before running a full crawl: the homepage, a service page, an article, a category page and any template with special functionality. Inspect those pages manually, then use a crawler to find patterns across the site. Record evidence rather than relying only on tool labels. For each issue, include a sample URL, the number of affected pages, the expected user or search impact and a test that will confirm the fix.
Useful tools include Google Search Console, PageSpeed Insights, browser developer tools and a reputable site crawler. Each tool reveals a different part of the problem; no single score replaces verification.
Frequently asked questions
How often should a site be audited?
Review critical checks after major releases and schedule broader reviews periodically. Large stores or frequently updated sites may need closer monitoring.
Does a perfect audit score guarantee rankings?
No. Technical accessibility is only one part of search performance. Relevance, content usefulness, competition and reputation also matter.
Next step
If indexing is inconsistent or a redesign has affected organic visibility, investigate shared causes rather than fixing isolated warnings. See Feed Flow’s digital marketing services for support connecting technical findings to an organic-growth plan.
