Technical SEO Checklist

Technical SEO makes sure search engines can discover, crawl, understand, and index the right pages without wasting attention on broken, duplicated, or low-value URLs.

Start with indexability

Check that important pages return 200 status codes, are not blocked by robots.txt, do not carry accidental noindex tags, and have canonical URLs pointing to themselves.

Pages that are placeholders, duplicated, or not ready should be kept out of the sitemap and marked noindex if they must remain accessible.

Clean up redirects and old URLs

Old generated pages should redirect to the strongest relevant replacement, not to another thin URL. This helps consolidate signals and avoids keeping low-value pages alive.

Redirect maps should be generated from data and tested for self-redirects, old destination slugs, and missing priority mappings.

Use Search Console after launch

After deployment, inspect priority URLs, submit the sitemap, and monitor redirect, 404, crawled-not-indexed, and duplicate-canonical reports.

Technical SEO is not a one-time checklist. It becomes a monitoring rhythm after the site is live.
