Formulas for the principles of search engine operation

[subornaakter20]

Each search engine uses its own unique algorithms for searching and ranking pages and sites, but the operating principles of all search engines are the same.

The process of searching for information that matches a user's request consists of several stages: collecting data on the Internet, indexing sites, searching by keywords, and ranking the results obtained. Let's take a closer look at each stage.

Data collection

Once the site is ready, you need to make sure chiropractor email address that search engine robots know about its appearance. You can place external links to your Internet resource or use other methods. As soon as the robot enters the site, it will begin to collect data on each page. This process is called crawling. Collection of information from the site occurs not only after its creation. The robot will periodically view the Internet resource to check the relevance of the information and update the existing data.

For both you and the bot (robot), such interaction should be mutually beneficial and comfortable. You, as the owner of the site, are interested in the bot doing its job quickly, without overloading the server, while collecting data from all pages as fully as possible. It is also important for the bot to do everything as quickly as possible in order to move on to collecting data from the next site in its list. For your part, you can check that the site is working, there are no problems with navigation, there are no pages that return a 404 error, etc.

Indexing

Even if the robot has visited your site more than once, this does not mean that the Internet resource will immediately become visible to the search engine and will appear in the search results. After collecting the data, the next stage of the site processing process is its indexing (creation of an inverted index file for each page). The index is needed for quick searching. As a rule, it consists of a list of words from the text and information about them (positions in the text, weight, etc.).

After indexing is complete, the site and individual pages appear in search engine results for user search queries. Usually, the indexing process does not take much time.
