Do you always want to know what is SEO? So in a simple sentence web search marketing technique is called the SEO or Search Engine Optimization. Whenever you enter any words in any web search engine like Google you get a list of results containing the search word, but the results are shown in an ordered list. Most of the users visit the sites that are at the top of the search result hence the website that come at the top of the result for that search word gets more traffic. But you must have seen some results have the same search words and still they appear at the bottom of the page, this is because the site at the top rank has optimized the page for the search engine, that is the website has done a better SEO.

SEO is a technique which helps websites in getting a high rank in the search results for a search query called key word when compared to other millions of websites. Thus a better SEO helps you get more traffic from search engines. So now I think you know what is SEO and the importance of it.

As now you know the SEO, lets take a look at how search engine works. To know the working principle of a search engine let us consider only crawler based search engine only.


How Search Engine Works


A crawler based search engine like Google, Bing, Yahoo etc. create their indexes or listings automatically using a crawler or widely known as spider. Spiders are the computer programs that crawl websites and fetch the data from each and every page and store them into the indexes. So when you search for any query the search engine gets the result from the index and shows the result. But the results are shown according to the relevancy and page rankings.

But I need to tell here that the way humans view a web page is completely different than a search engine view the webpage. Humans can view the complete design of the page where the search engine can only view the texts in a page and can not view the beauty of a web page. So all search engines are only text driven. So whenever a spider crawls a webpage it just parses the html tags, gets the data and creates the indexes. But the exact process of a search engine includes some more steps which are: Crawling, Indexing, Processing, Relevancy calculation and finally Retrieving the search results.


how search engine works


Now as you know that search engines are text driven so you must have come to know why SEO is most important thing for any website. SEO does the trick of optimizing a web page for search engine reader friendly, so that search engines could parse properly and calculate the accurate relevancy for a search query. Search engines like Google, Bing etc. change their algorithm to calculate the relevancy of a keyword against a webpage. So if you would like to stay at the top of the result page you need to do proper SEO according to the change of the algorithm.
