How do search engines work?

Search engines have three main functions:

Crawl: Search the web for content and browse the content and code found in each URL.
Index: The storage and classification of content found during the monitoring phase. By placing a page in the index, that page will have a chance to appear in search results.
Rank: Provide a list of relevant and relevant content by searching for a phrase. Search results are ranked according to the most relevant criteria.

What is search engine monitoring?



Crawling is the process by which a team of robots (called spiders) connects to the Internet and discovers new and updated content. Content can be of different types such as web page, image, video or PDF. But apart from any format, the contents are identified using links.

Search Engine Monitoring
The Google bot, called the Google Bot (Googlebot), starts looking at a few pages on the web. and then follows the links in it to discover new pages. By doing this. the monitor is able to find new content and add it to its index under the name Caffeine – a huge database of discovered URLs. As a result, the information requested by the user at the time. of the request is called in this way.

What is a Search Engine Index?


Search engines process and store discovered information in the form of an encoder. The index contains a huge database of content that is used by search engines when a user searches.

Ranking of sites in search engines
Right after the users’ search time, search engines start searching among the related content and sorting them by list according to the user’s search term. The operation of compiling this list is called ranking. In general, you can imagine that the higher a website ranks, the more relevant its content is to the search term.

It is possible to prevent the monitoring of the whole site or some of its pages or to prevent some pages from being indexed by search engines. While there may be reasons to do this, you must first make sure that the pages you are looking for can be tracked and indexed by search engines. Otherwise that page will not appear in search results.

At the end of this section you will find that you need to work with search engines, not against them.

Not all search engines are the same in SEO


Many beginners are amazed at the relative importance of certain search engines. Many people know that Google has the largest share of the search market, but how important is optimization for Bing, Yahoo, and others? The truth is that despite at least twenty major search engines in the world, the attention of the SEO community is focused on Google. but why? A short answer to this question is that most of the world’s searches are done on Google. If we consider the images, maps, and YouTube sections (owned by Google) in addition to the Google web section, more than 90% of the world’s searches occur on Google. This is 20 times the sum of Bing and Yahoo’s share.

Monitoring: Can search engines find site pages?


As you have learned so far, monitoring and indexing site pages is a prerequisite for being seen in search results. If you already have a website, it is best to check the number of pages indexed. This will give you a good initial view of the site pages.

One way to check the site index is to use the site operator: site: domain.com. Do a Google search for site: domain.com and enter your domain name instead of domain.com. By doing this, you will find out the number of indexed pages of the site in Google.

The number of pages that Google shows in such a situation is not very accurate, but you can get a basic idea of ​​the pages indexed and how they are displayed in search results.

Using this tool, you can register your sitemap (list of web page URLs) in it and see the number of pages in the Google index from this list. Of course, the functions of this tool do not end there.
