How does search engine works?



 How does Search Engines Work?

Google Changes The Search Engine Game
I’ve been online for a long time, since before Google was born that was before i started blogging I was studying all internet stuff like a joke, then by 2016 I jumped into serious blogging, my research became bigger and stronger. Back when I first 
started using the web I was a high school student and used search engines like 
Lycos, Looksmart, HotBot and at the time, Yahoo!, which was based 
on a human edited directory. The results were i"y, but that’s the best we had at 
the time and generally people did more “link surfing”, clicking links to go from 
site to site rather than use search engines to find what they wanted.
Google launched new search engine with a very basic homepage, a funny name and the key 
ingredient – amazingly valuable and relevant search results. At the time I had no 
idea how they did what they did and why they were di"erent, but it was clear they 
provided the best answers to the questions people went online to ask. 
If you have ever studied SEO you will realize there is a lot we don’t know about 
how Google works and the algorithms that power search results in general. We do 
know some key basic principles and it’s these that I have spent my time working on. I recommend you do the same.  Read more external link strategy
The core principle that forms the foundation for everything you do in SEO is 
PageRank. Before we move on I want you to be 100% clear on what PageRank is, 
so I have included an introduction for you below. In this section I draw upon some 
content I wrote to my blog. One article in particular explaining PageRank in simple 
terms was very popular because it teaches you only what you need to know 

What is Google’s PageRank? 


If you have ever done any reading without search engine optimization or were just 
curious how you can get your site to the top of the Google search engine results, 
understanding PageRank is vital. I’m going to introduce you to the basics of 
PageRank and also provide a brief discussion of how much you should really 
worry about PageRank if you are running a website or blog.
Google’s founders, Larry Page and Sergey Brin, invented PageRank and it forms 
the basis for how Google works. Google didn’t become the best search engine in 
the world by chance, it became the best search engine because it provided the 
best results. PageRank is the technology that gave Google its competitor-killing
edge, a way to greatly improve the accuracy and validity of a search response to a 
user query.
In essence PageRank provides a means to determine the value of a website for any 
given search term or keyword phrase. This value is determined by how websites 
link together with the more popular (and theoretically better) sites receiving more 
links. It’s these incoming links that help the site have a high PageRank value and 
thus display higher up in search results.
Let’s read how Google explains their PageRank system:
PageRank relies on the uniquely democratic nature of the web 
by using its vast link structure as an indicator of an individual 
page’s value. Google interprets a link from page A to page B as 
a vote, by page A, for page B. But, Google looks at more than 
the sheer volume of votes, or links a page receives; it also 
analyzes the page that casts the vote. Votes cast by pages that 
are themselves “important” weigh more heavily and help to 
make other pages “important.”
Important, high-quality sites receive a higher PageRank, which 
Google remembers each time it conducts a search. Of course, 
important pages mean nothing to you if they don’t match your 
query. So, Google combines PageRank with sophisticated text￾matching techniques to find pages that are both important and 
relevant to your search. Google goes far beyond the number of 
times a term appears on a page and examines all aspects of the 
page’s content (and the content of the pages linking to it) to 
determine if it’s a good match for your query.
The key rule to understand is that it is a combination of variables that determine 
how well your site performs in Google. These are the most important variables to 
worry about:
• Incoming links to your site.
• The relevancy (to your site’s subject matter) of the pages linking to your site
and the PageRank of these pages.
• The keywords that other sites use to link to your site.
• The keywords on your website in particular in places like page titles and
headlines.
Some of those factors you can control, others you can manipulate but not directly 
control. The important thing to understand regarding PageRank is that all the 
variables will determine how high your site shows up in search engine results. 
PageRank is the name for the technology that ranks sites and includes all those 
variables and many more. Now we have discussed on so many strategies but the is a lot more to know, there for in my further articles I will discuss all the basics to make it easier for understanding. You can also read
