How The Google Search Engines Work
The world of business is changing fast and it is depending vastly on search engines. Have you ever given a thought on how Google or Bing search engines work? How they crawl and index and particular page? It’s very important to know if you are blogger or a business man whose business depends on online traffic. First we try to understand the basic concept and then few other more complicated concepts.
So, lets come straight to the original question-How search engines work? Whenever you search anything, it scours billions of pages from its database tries to find the most relevant page according to your query.
Also, it ranks those pages according to the popularity of those pages. So, relevancy and popularity are two important aspects for higher search engine rank. Search engines consider hundred of factors to determine relevancy of the site. In fact, search engines never disclosed the factors that influence relevancy.
First we deliberate upon what is simple crawl?
Do you know whenever search engine spider visits a site, what it do the first thing? It collects the robot.txt files. At the same time, it collects the information about all the pages that it crawls. If there are internal links, it follows them. And, if they are external, they get put in the data-base.
It, then, pulls out all of these links from the database and connects them and assigns relative value to them which may be positive or negative.
Can you block search engine spiders to collect information about any particular page? Yes, you can do it. When you use robot.txt tag, search engines can’t crawl the page and cannot collect data about it. So, you have prevented the search engine spider. The catch is it can still assign link value metrics to these pages and it affects the domain authority.
The crux is whenever you make a website, ensure that it has proper category and content-silo structure. The search spiders should be able to easily crawl the information presented on various pages.How The Google Search Engines Work by Vishal Vivek
