Technical SEO (search engine optimization) refers to optimization on the technical side of a website, or more specifically, the back-end of the website from the code used to render the page to the hardware presenting that code per a user’s request. Technical SEO uses some best practices to encourage search engines to crawl URLs and to make it more efficient for search engines to crawl sites. A few goals of technical SEO include:

o Fast page load speed
o Mobile friendliness
o Strong website architecture/navigation
o Structured data to describe content
o Server response times

Technical SEO lays a strong foundation for the rest of your website to build upon. It is especially important with the now common use of JavaScript frameworks such as Angular and React.
