Search engines how they work

A modern search engine is a complex hardware and software complex. The information is collected, and when the user enters the search bar, the system gives out the most suitable documents in the form of a list.

Documents are sorted (ranked) and assigned a position in the search results based on their significance.Users are used to the fact that search is free for them, but at the same time, a modern search engine is one of the most effective business tools for both its owners and advertisers. The search service is a profit—oriented commercial enterprise. The more people use the search, the more advertising can be sold, so there is a competitive struggle between search engines: in order to retain users, it is necessary to constantly improve search results, build high—quality up-to-date output, as well as provide additional services – games, services, applications.

In order to attract users from search engines, it is important for site owners to understand the mechanisms of search engines and the basic principles of ranking, and also take into account that the number of offers from similar resources is growing, but Internet users (i.e. demand) is no longer becoming. To do this, you should look at your site and competitors’ sites from two positions: the owner of the business and the ordinary user. Now search engines are increasingly trying to “see” the site through the eyes of an ordinary visitor

Google Search Engine

Create pages primarily for users, not for search engines.Try not to resort to tricks to improve the ranking in search engines. Think about what makes your site unique, what is its value to users and what makes them come back to it again and again.

Your site should stand out from the competition.

How search engines work

Modern search engines process tens of thousands of requests per second. Let’s look at how the search mechanisms work.

Indexing process

Search engines have robots that visit your site. Indexing is a process during which search robots visit websites, collecting various information from their pages and entering it into special databases. Then this data is processed and added to the index. It is by the index that the search engine searches and provides links to sites based on user requests.

At the first visit, the “spider” checks the status of the resource. If its characteristics meet the requirements, the site is entered into the database. When the “spider” visits an already indexed page again, it is updated.

Search for relevant information

Today it is almost impossible to come up with a query for which a search engine can find less than 10 sources. For most meaningful queries, the search result is hundreds, thousands, millions of pages. The Internet is growing, and consequently, there are more and more pages. Therefore, the main purpose of the claim system is to show the most relevant information, that is, only those pages that match the request.

At first, relevant pages are sorted inside the site, and then the most suitable of them participate in a joint ranking.

Ranking process

Ranking is the process of sorting pages in descending order of their importance to the user (relevance). Since the founding of search engines, ranking algorithms have become significantly more complicated, and the quality of search has increased.

Update

New pages are being created on the Internet every day and information on existing sites is changing. All changes are accumulated in the search engine database, indexed, and then transferred to the basic search — this is called an update.

Search engine promotion

Search engine promotion (promotion by position) is a set of measures aimed at bringing the site to the first positions in search engine results by established keywords. This is the cheapest (although the longest in terms of preparation time) way to increase sales by increasing traffic to your resource.

Conclusion

It is important to understand that the first place in the search engine results for any query does not guarantee sales growth. In order for a site visitor to become a buyer, it is necessary to improve the usability of the site, improve the quality of the product or service, have excellent reviews and competitive prices.Search engine optimization (SEO) still requires resources and time (on average 3-6 months of work). However, due to the high conversion qualities of the site and the loyalty of the audience (the demand generated by users affects), the channel becomes an effective source of targeted traffic quite quickly.

Thus, search engine promotion can give the following results:

• increasing the number of site visitors
• promotion by a large number of queries has a positive effect on the attendance of your resource;sales growth
• people who have already been motivated to purchase a product or service come to the site, it remains only to keep them
• increasing brand awareness
• promotion by profile requests is a serious competitive advantage
