Technical SEO Checklist for Developers

A practical checklist for metadata, canonical URLs, crawlable links, structured data and fast pages.

Technical SEO starts with a website that search engines can fetch, understand and navigate. It cannot guarantee rankings, but a sound foundation helps search engines process your content.

Make content discoverable

Every important piece of content should have a stable URL and at least one crawlable link from another public page. HTML headings and clear navigation help both visitors and crawlers.

Write unique metadata

Give each important page a descriptive title and meta description. Use canonical URLs consistently and avoid publishing multiple identical pages under different paths.

Create a useful sitemap

List your preferred canonical pages in an XML sitemap. Keep thin internal search results and error routes out of the sitemap.

Measure real performance

Test Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift on representative devices. Efficient HTML, optimized assets and limited JavaScript reduce the work a browser must do.
