Before engaging in SEO website promotion, it is important to study the principles of search engines in order to achieve the desired results. This knowledge will be useful for developing an individual strategy for optimizing an Internet resource for specific keywords and will help bring it to the TOP of search results.

At the dawn of the Internet, only a small number of users had the opportunity to connect to it. The volume of available information was also small. At that time, the Internet was mainly used by employees of research organizations. Searching for information on the Web was not as popular as it is today.

The first attempt to organize access to electronic data via the Internet was made by the Yahoo! search engine, which appeared in 1994.

The company's developers created an open chiropractor email address catalog of sites, links to which were grouped by the corresponding topic. As the number of resources in the database grew, it became necessary to add a search option by catalog.

Such link directories used to be very popular, but today they have lost their relevance, because the number of sites is constantly increasing. For example, the largest of the modern directories on the Internet DMOZ (another name is the Open Directory Project) includes about 5 million sites, while the Google search engine database contains more than 8 billion links.

In 1994, the first real search engine, WebCrawler, appeared.

Also in 1997, the Yandex search engine, which is popular in RuNet, began operating.
