0 How Internet Search Engine Really Works? Think Again

                  How is actually Search Engines Work ? It was a really little mysterious thing to all of us until present, because of  the help of Paudel I was able to go through his article and modify it with some extra Information to present you. 

             The actual truth is it is that not humans who are search engines but the web spiders or bots who are created by humans. with this you'll able to know that how humans and search engines view the web page contents. Search engines are also text-driven. They are always searching for rich king quality posts so when you are blogging it doesn't matter if you get ideas from a somebody's blog but donot try to copy and paste the whole thing or named it as a your creation!

Search Engines performs basically six acts to deliver the best and quality web results.

  • Crawling

  • Meta Tags

  • Indexing

  • Processing

  • Calculating relevancy

  • Retrieving Results   


       Before a search engine can tell you where a file or document is, it must be found. To find information on the hundreds of millions of Web pages that exist, a search engine employs special software robots, called spiders, to build lists of the words found on Web sites. When a spider is building its lists, the process is called Web crawling. 

      But in the case of the Google this crawling process is carried out by the Google bot. These kind of Spider, Crawler or Google-bot are responsible for indexing everything that they find throughout their way while following links from one page to another. After the completion of crawling process the next step is of indexing the content in search engine database.

Meta Tags

      Meta tags allow the owner of a page to specify key words and concepts under which the page will be indexed. This can be helpful, especially in cases in which the words on the page might have double or triple meanings -- the meta tags can guide the search engine in choosing which of the several possible meanings for these words is correct. For each post you will be able to add a meta description as a few words but the article will be fully depended on it in search results, and web-spiders will also notice the article if is with relevant article. In the site there is Meta tags you can edit in template, Web-spiders mainly go through that tags to decide what site this is and whether to add it or not and if they noticed about the site they report the site with their results and your site will rise to top in search results.

    However, a danger in over-reliance on meta tags, because a careless or unscrupulous page owner might add meta tags that fit very popular topics but have nothing to do with the actual contents of the page. To protect against this, spiders will correlate meta tags with page content, rejecting the meta tags that don't match the words on the page.



    Whenever a search is made in a search engines with specific keywords, searches go to pull up information from the giant database. Since it is likely that millions of pages contains the search keywords that are stored in the giant database of search engine. Therefore the search engines start to calculate the relevancy of each and every page in its giant database to indexed it on their web search results page.

Calculating Relevancy

     Due to having millions of pages with similar search keywords, the search engines start to calculate the relevancy of each pages stored in their database. For this process they uses their special program called algorithms. The algorithms used by search engines varies from each other. For instance, the algorithm used by Google is different from Yahoo! and Bing. Each of these algorithms has different relative mass for keyword Factor, meta-tags or links. This is the reason why search engines give different web search results for the same search keywords. It is known fact that major search engines like Google, Yahoo!, Bing, Ask etc. keep changing their algorithms periodically. 

     Hence if you want to index your web pages at the top of web search results then you also need to adapt your site pages to the latest update or changes.This is the best reason to devote and invest your permanent efforts to SEO, if you want your site at the top of index page in search engines.

Retrieving Results

   After calculating the relevancy of site indexed in search engines, retrieving results is nothing more than simply displaying them in the browser. These results are sorted from the most relevant to the least relevant sites content indexed in search engines. 

Principle of Operating Search Results by Different Search Engines

      Basically the principle of operating search results by search engines are similar. But minor differences between their algorithms leads to major changes for retrieving results by calculating the relevancy of the sites. Perhaps for different search engines different factors are important to retrieve best and accuracy result. Some SEO expert joked that the algorithm used by Bing is completely opposite to the algorithm used by Google. Now you can understand and imagine that the algorithm used by Google is advanced and is completely different to the others search engine algorithms. About more than 80% of the traffic from search engine is obtained from Google and rest is from search engines and directories like Bing, Yahoo, Ask, etc. 

        This doesn't mean you should optimize your site for Google only because rest 20% of the traffic also matters a lot in your traffic source. For Yahoo! and Bing on-page keyword factors matters a lot as a primary importance, while for the Google internal and external links count are very much critical to rank well. Therefore you need to be patience and hard working towards optimizing your site to rank well in Search Engines and Search Directories.

Be with the Theory and you won't Fail
