Technical SEO is the process of ensuring that technical on-site elements of a webpage are configured to maximise the potential organic visibility in search engines. This includes making sure the website can be crawled easily and has an architecture best fitting to user experience and entity classifications.

The practice of technical SEO itself is concerned with web technology factors that directly impact a search engine’s ability to crawl, render and index a website — which ultimately impacts on a site’s ability to rank for relevant keywords in search engines.
