Technical SEO

SEOTerm

Making sure search engines can crawl, render and index your site without obstacles: site structure, speed, mobile handling, redirects, status codes, sitemaps, robots.txt and canonical tags.

Example

Meera's developer finds that her product filters create thousands of near-duplicate URLs and that old product pages return errors. Fixing these is technical SEO.

How you'll hear it

“Content is not the issue; half the site is not even indexed. This is a technical SEO problem.”

Don't confuse it with

  • On-page SEO: what a page says and how it is marked up. Technical SEO: whether search engines can reach and process it at all.
