Review crawlability, indexation, canonicals, redirects, sitemaps, internal links, rendering and page experience with a practical audit workflow.

Start with crawl access

Check robots.txt, meta robots directives, authentication, status codes and whether important pages can be reached through internal links. A page cannot compete if search engines are blocked from discovering or rendering it.

Compare crawled URLs with indexable URLs

Large differences can reveal parameters, duplicate paths, internal search pages, staging URLs or canonical problems. Build a clean inventory of URLs that should exist and those that should not be indexable.

  • 200 indexable pages
  • Redirects and chains
  • 4xx and 5xx URLs
  • Canonical targets
  • Noindex pages
  • Orphan or deeply buried pages

Review canonicals and duplicate content

Canonical tags should reinforce the preferred URL, not fight internal links or redirects. Check faceted navigation, HTTP/HTTPS variants, trailing slashes and tracking parameters for inconsistent canonical signals.

Audit XML sitemaps and internal linking

Sitemaps should contain canonical, indexable URLs and use accurate last-modified dates when available. Internal links remain the stronger discovery path, so important pages should also be reachable through navigation and contextual links.

Check rendering and performance

Test mobile rendering, layout stability, image sizing and whether critical content depends on fragile JavaScript. Core Web Vitals are part of page experience, but performance work should focus on real user bottlenecks instead of chasing a perfect lab score.

Prioritize by impact and effort

Not every crawler warning deserves immediate work. Fix blockers affecting important templates first, then clean systemic issues, then lower-impact warnings. A useful technical audit ends with an ordered implementation plan rather than a long unranked export.

Use real search data with crawl data

A crawler shows what it can discover, but Search Console can show which URLs Google is seeing, indexing and surfacing. Compare the two sets. Pages with impressions but weak internal links may need better architecture, while crawled pages with no search value may need consolidation or index control.

Log files, when available, add another layer by showing how search-engine bots actually spend crawl activity. They are especially useful on large ecommerce, publishing and faceted-navigation sites.

Validate fixes after deployment

Technical SEO is not complete when a recommendation is written. Re-crawl affected templates, test redirects, inspect canonicals and verify that XML sitemaps contain the intended URLs. For important pages, use Search Console URL inspection after the change and monitor coverage or performance trends.

Keep before-and-after notes for major fixes. This makes it easier to separate the effect of a technical change from seasonality, content updates or algorithm volatility.
