Technical SEO checklist
Technical SEO ensures search engines can discover, crawl, and understand your site across desktop and mobile. This checklist now combines launch checks, mobile-specific essentials, and the most important indexing, crawl, speed, and structured-data controls into one practical audit asset for ongoing use.
Indexing, crawl, and discovery
Confirm important pages are not blocked by robots.txt or noindex, submit clean sitemaps, and verify index status in Search Console. Check redirects, canonicals, response codes, and internal links so important templates are easy for Google to discover and revisit. Treat crawl coverage and index eligibility as the first technical gate before deeper optimisation work.
- No unwanted crawl or noindex blocks
- Clean sitemap and response codes
- Priority pages linked and discoverable
Performance, mobile, and structured data
Check Core Web Vitals, page speed, viewport handling, tap targets, and content parity on mobile. Make sure the mobile version contains the same important content and signals as desktop, and validate any structured data that supports products, organisations, breadcrumbs, or other search features. If mobile experience is weak, fix that before worrying about marginal desktop gains.
- Core Web Vitals and mobile checked
- Responsive layout and usable tap targets
- Structured data valid and relevant
