Technical SEO Checklist: Core Web Vitals and More

A useful technical SEO checklist helps search engines discover and understand important pages, while making the site easier for people to use. It should cover crawlability, indexing, mobile experience, page performance, and the structure of the content—not just a single audit score.

1. Check crawling and indexing

Confirm that important pages can be reached through internal links and are not unintentionally blocked by robots rules or noindex directives. Review the XML sitemap for canonical URLs, remove redirects and non-indexable pages from it, and check that important pages return the expected status code.

For a site migration or URL change, map old URLs to their closest relevant destinations and test the redirects. Avoid sending every removed page to the homepage; that can confuse visitors and search systems.

2. Make site structure easy to follow

Organize pages around the questions and tasks your audience has. Descriptive page titles, clear headings, useful internal links, and readable URLs help people understand where they are and how related information fits together.

Set a preferred canonical URL for pages with duplicate or near-duplicate versions. Use structured data only when it accurately describes visible page content, and validate it before relying on search enhancements.

3. Review mobile usability and Core Web Vitals

Test real page tasks on narrow screens: reading, navigation, forms, buttons, and media. Check that tap targets are usable, text remains readable, and content does not shift unexpectedly while loading.

Core Web Vitals help assess loading, interaction responsiveness, and visual stability. Use field data when available, then investigate the pages and assets behind weak results. Optimize large images, avoid unnecessary scripts, and test representative devices and connections; do not treat a lab score as a substitute for user experience.

4. Measure and prioritize fixes

1. 01Start with the pages and tasks that matter most to the business.
2. 02Separate crawl, indexing, content, and performance issues.
3. 03Fix issues with clear user or search impact before minor warnings.
4. 04Re-test after changes and monitor the affected pages over time.

Technical SEO is ongoing maintenance, not a guarantee of ranking positions. A clear audit turns the findings into practical work for content and engineering teams. Learn more about our SEO and content audit process.
