Run your first technical SEO checks

Record evidence for common accessibility and indexing problems.

Technical SEO begins with whether important pages can be accessed and interpreted. A beginner audit should produce a small set of evidence-backed issues, not a long export with every item labelled critical.

Check five fundamentals

  • Access: does the preferred URL load for a signed-out visitor, and does it return the intended page?
  • Indexing instructions: is an important public page unintentionally marked noindex?
  • Preferred version: are internal links and canonical signals consistent with the URL you intend to use?
  • Mobile usability: can a visitor read, navigate and complete the main action without obstruction?
  • Performance: what feels slow, and what do a diagnostic test and available field data show?

A crawl block and an indexing exclusion are different controls. A crawler generally needs access to read a page's noindex instruction. Canonical signals deal with representative versions of similar content; they are not access protection. Private information needs appropriate authentication.

Practise safely

Choose three public pages and inspect them. Record observations before making changes. For a canonical or indexing issue, ask the website owner or developer to confirm the intended behaviour. Do not change site-wide robots settings as an experiment on a live business website.

Your deliverable

Three audit records containing URL, observed problem, evidence, likely impact, proposed action, owner and validation method. Separate confirmed problems from questions requiring further investigation.

After a fix, repeat the relevant check. A better diagnostic score is useful evidence about that test; it is not by itself proof of improved sales or rankings.

Check your understanding

Can a crawler read a page's noindex instruction if robots.txt prevents it from fetching the page?
