Search engine operating principle

If you have chosen SEO-promotion for your site, it is advisable to initially understand the principle of operation of search engines (PS) to obtain positive results. This will help build your own strategy for optimizing your resource for the right search queries so that you can probably be on the first page of the search engine.

The main tasks of the PS

  1. Give the user the correct answer to the query entered in the search bar and thereby satisfy it in order to prevent the use of competing PS. To do this, in TOP 10 searches, the results should be as suitable as possible for the user's request.


  2. Provide traffic monetization. That is, first of all, to produce a result that will facilitate profit by the site owner, for example, using contextual advertising.

How does the search engine work?

There are a lot of search engines to date. Naturally, in each of them the search is built on its own algorithms, but in general the principle of operation of search engines is quite similar.

At the moment when you created the site and the bot of one of the search engines found out about it (as a result of purchasing links or in any other way), it “comes and starts to roam” on the pages. 

The principle of operation of search robots is based on the implementation of several stages:

  1. Data collection. Using bots, PS collects the necessary information from all resource pages (texts, images, videos, etc.). 
    These processes begin after the launch of the site and subsequently occur according to the schedule compiled by the robot. Due to this, page data is updated from time to time for changes.
  2. Indexing - assigning each page a specific index that will allow you to quickly search their contents. 

From now on, your resource or some of its pages can be displayed on the search engine distribution pages for individual requests. Well, on which page it will depend on the level of its optimization.

Basic principles of ranking sites in search engines

In order for your site to get into the TOP 3, well, or at least in TOP 10, you need to know all the basic criteria of search engines and try to optimize it in such a way that it matches them. These criteria can be divided into two main groups:

  • textual;
  • non-textual.

PS text criteria

In this case, site ranking is based on an assessment of the quality of the textual content of the pages. Work with them is carried out at the stage of creating the semantic core of the site and filling it with textual content.

It is understood that the PS gives on the first page of the search the results that are most relevant to the user's request.  That is, their contents most accurately meet the necessary criteria and must satisfy it. Also, attention is drawn to the correct filling title phrase (title), page descriptions (description) and key availability header query (H1, H2, etc.). You will learn more about this in separate articles.

Non-text criteria PS

Work with them occurs after the publication of the site and its indexation. The principles of determining the rating of Internet resources based on non-textual criteria are not based on an assessment of the quality of their content. They contain slightly different factors for ranking the site - an assessment of the external reference profile.

The system works on the principle of accounting for the number of links to your resource, assessing the authority of the resources being referenced, checking registrations in the site catalogs. 
An analogy can be drawn with the conclusions about the quality of a particular product based on feedback from consumers, suppliers, sellers, etc.


Conclusions for those who create and promote sites

Having thoroughly studied the principle of the search engines and tracking innovations in them, you will learn how to create sites that will easily get to the first pages of search results. And most importantly, they will be able to remain in these positions for a long time, since they will fully meet the needs of users.
