How to use the search engine?

The user can access the search engine through a browser on the tablet of his computer, mobile device or any other device.

You can easily search by going to the home page of any search engine by typing a keyword in the search box.

How does search engine works?

Each search engine uses different algorithms to see the search results for the user.  The search engine works primarily in three stages, which is as follows.

Crawling

Indexing

Classification

The search engine always follows these three basic steps to work. So, let’s understand this in detail.

Crawling

Search engine work always begins with crawling.  In this process, the sites are scanned and the details of all their pages and publications are obtained, such as title, link, image keyword, etc.

Indexing

After that, an indexing process is performed in which all the data found during the scan is organized and maintained in the database from behind.

Recover and sort.

This is the last step to how work search engine.

In this step, when the user searches for the search engine, according to his query, the corresponding page that matches his query appears.

The search engine shows the search result in the list according to its algorithm.

They have their own different criteria for the page that the search engine selects from the saved database to show results during the search.  The page that best matches the user’s search and is important shows the top of it.

Do all search engines show similar results?

No, it is not necessary for all search engines to show the same results.  Each search engine has its own different algorithm according to which it searches results according to the user’s query from its database.

The result depends on different things, such as where the user is looking for before, what the user has searched for, etc.

That is, the basis for viewing the results of each search engine is different, according to which they mostly show different results.

What happens when you search for a search engine?

When a user in a search engine searches by typing their query, the search engine identifies the important pages associated with the query of all pages that are indexed, and the use of the algorithm classifies the relevant pages into a result set.

Each search engine shows different important results according to the search query.

For example, if you search by typing something on Google, the results that appear at the top are not necessary if you type the same keyword and search Bing, then the same results appear.

The results that the search engine sees depend on many simple things.

Why does the search engine not index a page?

There are many reasons why a page is not indexed by search engines.

Robots.txt.

Many times, developers give a link to the sites page in the robots.trust file, which blocks them, that is, the Google robot does not know how to index it.

Sitemap.xml.

When you do not create a sitemap.xml file for your site or do not send the sitemap.xml ko file to the webmaster tool after publishing the publication, the search engine robot does not know how to index the link to the site.

If your site link is not indexed, once you resubmit the site map in the webmaster tool

Crawl errors.

Many times search engines do not know how to crawl the site, because the links on the new site page are not indexed.  If this is the time, you should go to the webmaster tools and check the tracking error and fix it

Blocked by-htaccess.

Hatcase is a file that your server resides in the root folder of your site, its main function is to create URL rules and control the configuration of the site.

Many times the site index stops due to the application of incorrect rules, so if you do not know the rewrite rule, do not change this file.

NOINDEX in the Meta Tag.

The search engine uses a meta tag to block the ship and is written as noindex.

<META NAME = “ROBOTS” CONTENT = “NOINDEX, NOFOLLOW”>

If such a meta tag is placed on any page of the site, the page’s search engine will not index it.  If you want to index the page, this tag must be verified if the tag is not placed on the page.
