Technical SEO
Technical SEO is the optimization of site architecture, crawlability, indexation, performance, and structured data so search systems can access and interpret content correctly.
Also known as: tech-seo · site-technical-optimization
Why it matters
Great content on a broken technical base underperforms: pages stay unindexed, Core Web Vitals fail, schema is invalid, and crawl budget wastes on faceted duplicates. Technical SEO removes friction so relevance and authority can actually register.
How it works
Audit robots.txt, sitemaps, canonicals, redirects, status codes, mobile rendering, and page speed. Fix index bloat, orphan routes, and JavaScript rendering gaps. Add valid structured data for visible entities. Monitor Search Console coverage and crawl stats after changes.
Common mistakes
- Noindexing staging but leaving it linked from production sitemaps.
- Chains of 302 redirects during migrations instead of clean 301 maps.
- Injecting schema that does not match visible page content.
- Chasing perfect Lighthouse lab scores while index coverage bleeds.
Best practices
- Treat GSC Index Coverage as the source of truth for indexation health.
- Ship redirect maps before DNS cutovers.
- Validate JSON-LD after template changes.
- Pair CWV fixes with LCP element prioritization on money pages.
Learn Domains perspective
Your checkout page lost impressions after a deploy and nobody noticed for weeks. In Learn Domains, index coverage drops and Core Web Vitals failures show up in your Digital Asset Score and Mission Brief as concrete orders, fix the noindex on `/pricing`, improve LCP on your top landing page, not a generic technical audit checklist.
