Check crawl access, indexing, canonical URLs, sitemaps, performance and structured data. Turn technical SEO findings into prioritised actions.

A technical SEO audit should produce actions that can be verified. Hundreds of warnings without context or an order of work do not tell a team what to fix first. Start with commercially important pages and follow their path from discovery to rendering.

Can the page be discovered and accessed?

Check internal links, the sitemap and server responses. Important content should not depend entirely on internal search or a complicated interaction to be found. Navigation links need genuine, clear destinations.

Review robots.txt separately from meta robots. Blocking a crawler is not equivalent to a noindex instruction: a blocked crawler may be unable to read that instruction. Document which pages should be indexed and which should be excluded before changing the rules.

Are signals pointing to the right version?

Compare public URLs with canonicals, redirects and sitemap entries. Examine parameters, trailing slashes, alternative domains and language versions. Resolve contradictory signals at their source rather than adding more tags around them.

For bilingual pages, verify hreflang relationships between genuine equivalents. A translation should reference the other language version of the same content, rather than that language’s homepage.

Are content and functionality available?

Inspect the published page on mobile as well as desktop. Main content, titles and important links need to be accessible. Check forms, navigation and error states. A strong technical score cannot compensate for missing content or a broken contact button.

Assess performance with laboratory tests and real-user data where available. Do not treat one test as a final verdict. Device, connection, caching and third-party scripts can all affect the result.

Validate structured data and prioritise fixes

Validate JSON-LD and compare its properties with visible information. Article authors, titles and dates must be accurate. Remove contradictory duplicates and never invent reviews or outcomes to satisfy a validator.

Rank issues by impact, affected page count and implementation effort. An accidental noindex on service pages takes priority over a small improvement to an archive image. Record evidence, an owner, the proposed remedy and an acceptance test for each finding.

Frequently asked questions

Is an automated audit enough?

A crawler identifies many problems but does not know every business objective. Manual review is necessary to interpret findings and avoid inappropriate fixes.

When should an audit be repeated?

After migrations, platform changes or major template updates, with periodic checks matched to how frequently the website changes.
