Learning objectives#

  • Follow an audit checklist
  • Use crawlers and Search Console together
  • Prioritise issues by impact and effort
  • Report findings clearly

Explanation#

Crawl the site with a tool such as Screaming Frog (free up to 500 URLs) or Sitebulb to find broken links, redirect chains, missing titles, duplicate content and canonical problems.

Compare with Search Console: indexed pages, coverage errors, Core Web Vitals, enhancements.

Check robots.txt, sitemaps, mobile usability, structured data validity and internal linking depth.

Prioritise: issues that block indexing first, then templates affecting many pages, then individual page improvements.

Expected output
A short, prioritised list that developers can turn directly into tickets.

This example is illustrative. Copy or download it and run it in your own environment; the expected output is shown above.

Step-by-step explanation#

  1. Crawl the site.
  2. Combine with Search Console data.
  3. Group issues by severity.
  4. Estimate effort and schedule fixes.

Real-world use case#

A quarterly audit catches a template bug that removed canonicals from 200 pages before rankings dropped.

Common mistakes#

Huge reports with no priorities

Developers need a short ordered list, not 300 warnings.

Fixing cosmetic issues first

Indexing blockers and site-wide templates have far more impact.

Best practices#

  • Crawler + Search Console
  • Prioritise by impact and effort
  • Fix templates before single pages
  • Re-audit after releases

Remember this#

Crawl → compare → prioritise → fix → re-check.

Indexing blockers first.

Templates multiply impact.

Practice exercise#

Your task: Put in order: missing alt text on 3 images, robots.txt blocking /tutorials, duplicate titles on 500 pages.
