Website optimization is a combination of certain methods and measures that allow you to bring your website to the leading positions in search engine results and get ahead of the competition. The most popular search engine in the world is Google. Search engine optimization of a website is divided into two categories: internal optimization and external optimization. Internal optimization involves working with the structure of the site. The goal is to make it more user-friendly and understandable. External optimization is the building of the link mass, namely: getting links to the site from other web resources. Links from trust-free, thematic sites give excellent results.
