Technical SEO represents a set of optimization activities that focus on technical side of website with goal of improving its indexing and visibility in search engines. Unlike content SEO, technical SEO focuses on factors such as page loading speed, correct URL structure, internal linking, XML sitemap, or correct settings of robots.txt.

Important part of technical SEO is also optimization for mobile devices, website security using HTTPS, and removal of technical errors that can prevent search engines from indexing content. For online stores, technical SEO is extremely important because it allows search engines to efficiently crawl large number of product pages. Correctly configured technical SEO creates solid foundation for growth of organic traffic.
