2. I have already explained about what is SEO and Search engine results pages
(SERPs), You came here to learn How a search engine works. I would like to
explain to you more about the search engine.
Everything is digital in coming days and there is a huge database on the
internet. Users can find out any information in the search engine. You know
search engine is the main essential part in digital to search required
information for users.
Did you know how many times per day you are using the Google search
engine? The search engine is becoming part of our daily life to use them
shopping tool, learning tool, fun and also for business. You may be thing
what is mean by a search engine and how a search engine works. Before
that, we will understand the history of Search Engine.

3. History of search engine:
The foundation for the search engines was laid in 1990. By the Canadian
McGill University in Montreal with the search engine Archie.
The students Alan Emtage, Peter Deutsch and Bill Heelan began to
program so-called search robots that combed the Internet systematically
and collected information.
In November 1990, Archie V1 was born at University of Minnesota and
Gopher was unveiled to the public in 1991. Largely developed by Paul
Lidner and Mark P. McCahill. With him, even complex linkage search
(“and”, “or”, “not”) was possible.
Nevertheless, in 1992, Archie was one of the most widely used Internet
services, though it was not able to search text but only files and folders.

4. By the mid-1990s, nearly every organization that had Internet access.
Such as universities, but also governments had a gopher server and
provided information to the general public from all areas.
With the upswing of the WWW, however, the time of the so-called
Gopherspace came to an end. The cause for the decline was also the
decision of the copyright haltenden University to charge for the
commercial use of Gopher fees.
Today there are very few gopher servers left and gopher is thus largely
out of use and is forgotten.
The real reasons for the departure of Archie were mainly legal problems.
Which led to the fact that within a short time all Archie servers were
discontinued worldwide.

5. WWW standard released:
In 1993 the WWW standard had released for free use. The first web
crawler with the name “The Wanderer” was programmed and also, the
first websites were created.
“The Wanderer” Started by Mathew Gray, a Software Engineer from the
MIT (Massachusetts Institute of Technology) spent more than 10 years in
Google.
There were already 130 websites according to the WWW standard in June
1993.

6. Birth of Aliweb:
The birth of Aliweb (Archie-Like Indexing of the Web) was in October 1993.
Here, the operators of web servers had to put a description of their service in
a file to become part of the Aliweb index.
In December 1993, the search engines Worldwide Web Worm, Jump station
and RBSE Spider came to the net. Worldwide Web Worm and Jump station
were crawlers that indexed websites by URL and title. RBSE Spider was the
first search engine to show their results according to their own ranking
system. These search engines are no longer available today.
In April 1994, another search engine went online. The search engine
WebCrawler could show a hit list sorted by ranking. In 1995 she was sold to
AOL, one year later to Excite.
In July 1994, the search engine Lycos, a work by Michael Mauldins, went
online. The word frequency of the search terms within the web pages as well
as the proximity of the search terms among each other in the document
were the main criteria.

7. Birth of Yahoo:
In 1994, the birth of Yahoo! (Yet Another Hierarchical Officious Oracle).
Stanford University’s Electrical Engineering students David Filo and Jerry
Yang published a collection of their best web addresses in an online
directory service.
In 1995, the market discovered the search engine segment. The first
products of search engines with commercial orientation are created:
Infoseek, Architext (later renamed Excite) and AltaVista. One year later,
Inktomi Corp. whose homonymous search engine became the basis of
Hotbot and other search sites.
AltaVista had until a few years still taken a large role. The “Scooter” robot
developed by AltaVista was enormously powerful. So AltaVista became
next to Yahoo! at the time to one of the leading Internet services of the
WWW.

8. Developing a search engine called BackRub:
Also in 1995, the two founders of Google met at Stanford University: the
students Larry Page and Sergey Brin. There you start developing a search
engine called BackRub.
BackRub was developed entirely by Larry Page. So only his name is
immortalized in PageRank. BackRub was supported by 3 fellow students.
Surprisingly, Sergey Brin comes after Scott Hassan and Alan Steremberg
only in 3rd place. Sergey has programmatically only distinguished by bug
fixes, but otherwise, leave all the work to Larry and his 2 colleagues. The
other two students left the project shortly afterward.

9. Two metasearch engines appeared in 1996: MetaCrawler from the USA
and MetaGer from Germany MetaGer. Until Google’s market penetration,
metasearch engines were considered to be one of the most interesting
sources of information, since the search engine’s search engine mostly
contained only parts of the internet. Metasearch engines forward the
queries of the user in parallel to several search engines and summarize
the hits formatted.
In late 1998, Larry Page and Sergey Brin published their innovative search
engine ranking technology entitled ” The Anatomy of a Large-Scale
Hypertextual Web Search Engine .” A little later, in September 1999, the
search engine Google starts in beta status. One year later, the search
engine becomes commercial.

10. Beta-Based Google
Beta-Based Google already reached 10,000 searches per day. In addition,
the clear user interface, the speed and the relevance of the search results
offered a quality that was not available at that time, which allowed Google
to attract many users.
Today, one can say that there are three major search engines on the Web,
based on the number of documents entered. These are besides Google,
Yahoo! Search, which was able to secure a high market share in the spring
of 2003 through purchases of several search engines, and Microsoft’s MSN
Search or Life Search.

11. What is a search engine?
A search engine is a software which is used to search the information on the
internet (World Wide Web) and it displays the related information in SERPs
(search engine result pages). Results are a combination of Web pages, video,
images, news etc.

12. When a user is searching for any information by entering the keywords or
phrase into the search engine then it searches the relevant information in
the giant database and returns to the user.
When you are thinking about a search engine in your mind comes to Google
search engine. But there are different types of search engine in the world
and different search engine used by different countries but most of the
countries using Google.
Google search engine has more users because Google gives the user
expected results and it is the most users friendly.
You may be thinking about how users are getting related information by
entering keywords in the search engine through the internet. I would love
to explain to you how the search engine works.

13. How do search engines work
When users are searching the information on the internet by using the
search engine and search engine collects all the related information from
the database and shows all results in SERPs (Search engine result pages).
User type word or phrase in the search engine and get the related
information. But a lot of people don’t know what is happening inside that
search box when they type in their search queries.
All search engines work these three functions before showing the results
to the users.

14. Crawling:
Software such as crawlers, bots or spider is scanning the sites and
fetching all the information from each page title, images, keywords, and
other linked pages etc.
Crawlers have the capacity to search a large range of websites and the
same period of time it collects a large amount of information. Crawler
visits each page as fast as possible when crawler visits a page it collects
all the links then crawler visits each web page to link to the website.
Crawler does continuously and keeps the track changes done by the
website. So that, crawler get to know which page is added or deleted.

15. Indexing:
It is the process of creating an index for all the fetched web pages and stores
all the information in the giant database according to the category. Indexing is
a very important task to rank the website and all websites appearing on
search engine result pages (SERPs) and it comes from an indexed database. If
you want to rank your website in search engine and should have indexed your
website by the search engine.
Serving:
Serving user expected result is very important. So that search engine gives the
user expected information. When users are typing keywords in the search
engine. The search engine performs some action like searching the user intent
keyword, searching indexed web pages related to the keyword. Ranking and
returning web pages of relevance and importance.
Search engine algorithms often change but search engines work to improve
their methods of giving the best result to users. These three functions will
helps the search engine to give the best result to users.

16. CONCLUSION
Search engines are very important to search the user with expected
information. By using search engine users are getting the satisfaction
results and everyone using the search engine for their queries and
getting the answer.
