is a search engine, how do search engines work, how can you use it, which
search engines are great.
Search engines are of great importance in the world of Internet.
So let's get complete information about the search engine.

What is a search engine?
A search engine is a web-based tool that allows Internet
users (users) to search through the World Wide Web (WWW).
When a user searches by typing in a keyword or phrase search
engine, then many results are seen from them, which contain website links,
images, videos and other types of data.
The content that is shown to the user by the search engine is
called Search Engine Result Page (SERP).
Google and Yahoo are famous search engines that are mainly
used by Internet users right now.
How to use search engine
The user can access the search engine through a browser on
their computer tablet, mobile 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 the search engine works
Each search engine uses different algorithms to see results
of the search to the user. The search engine works mainly in three stages which
is as follows.
Crawling
Indexing
Ranking
The search engine always follows these three basic steps to
work. So let's understand about this in detail.
Crawling
Search engine work always starts with crawling. In this
process, it scans the sites and gets the details of all its pages and posts
such as title, link, image keywords etc.
Indexing
After that an indexing process is done in which all the data
found during crawling is arranged and kept in the database from one back.
Retrieve and Rank
This is the last step of working the search engine.
In this step, when search engine is searched by the user,
according to their query, the relevant page which matches their query, appears
as a result.
The search engine shows the result of the search 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 matches the most according to the user's search and is
important shows the top of it.

Do all search engines show similar results?
No, it is not necessary that all search engines 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 what place the
user is searching from before, what the user has searched about it, etc.
That is, the basis of seeing the results of every search
engine is different, according to which they mostly show different results.
What happens when a search engine is searched?
When a user in a search engine searches by typing their
query, the search engine identifies the important pages associated with the
query out of all the pages that are indexed, and using the algorithm classifies
the relevant pages into a set of results.
Each search engine shows different important results
according to the search query.
For example, if you search by writing something in Google,
then the results which are coming up on top, it is not necessary that if you
write the same keyword and search in Bing, then the same results come up.
The results that the search engine sees depends on many
simple things.

language are you using to search?
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, the developers give a link to the page of the
sites in the robots.trust file, which blocks them, that is, the Googlebot does
not know how to index it.
Sitemap.xml
When you do not create a sitemap.xml file for your site or do
not submit the sitemap.xml file ko to the webmaster tool after publishing the
post, then the search engine bot does not know how to index the link to the
site.
If your site's link is not indexed, then once submit sitemap
again in webmaster tool
Crawl Errors
Many times search engines do not know how to crawl the site,
due to which the links of the new page of the site are not indexed. If this is
the time, then you should go to webmaster tools and check the crawl 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 applying wrong rules
in it, so if you do not know the rewrite rule then do not change this file.
NOINDEX in the Meta Tag
The search engine uses a meta tag to block the boat and is
written as noindex.
<META
NAME = "ROBOTS" CONTENT = "NOINDEX, NOFOLLOW">
If such a meta tag is placed in any page of the site then it
will not be indexed by the page search engine. If you want to index the page,
this tag must be checked if the tag is not placed on the page.

how it works. If you like this information, then share it with more people. If
