How search engine works?
First of all as a SEO know that search engines are not humans and the way to see web pages aren’t same. Search engines are text based driven I mean that they only read text on your site and not see the beauty of your web pages like pictures you put, cool designs, not enjoy sounds and the movement of movie that you put in your website. Instead of this, Search Engine crawler looking for a particular site item mainly text on your site and get the idea that what a site mean for. Search Engine performs several of activities to deliver the search result such as crawling, indexing pages, processing, checking and calculating relevancy and retrieving.
Search Engine activity on any website is explained as:-
1. Search engine first of all crawl the web pages to see what is on web page. This task is done by a software that is known as a crawler, spider. Crawler name is different on different search engine like,
- Google = Google Bot
- Yahoo = Yahoo Slurp
- MSN = MSN Bot
- Bing = Bing Bot
2. Spider as mention above is named different as different search engine is. Spider follows links from one page to another and indexes everything they find. It is impossible for a Spider to visit regularly or daily webpage to see a new page or existing one is modified. Sometimes a crawler even not visiting to your site for a month or two.
3. After a page is crawled then index is take place. The indexed page is stored in database from where later can be retrieve at any time. The process of indexing is to identify the words and expression that best describe that page and assign the page to the best keywords. It is not a easy task and sometime it not retrieve a right page but if you optimize your page correctly then it will be easy for crawler to indexing correctly and get the right page and for you a better and higher rank on search engine!
4. When a search query take place, Search Engine processes it and matches the search string with the indexed pages in the database. It is not just one or two pages its around millions of pages that related to that search string. Then search engine starts calculating of relevancy of each indexed pages with that search string. There are many of and different algorithms to calculate the relevancy. Each of these algorithms have different factor to calculate relevancy like keywords density, links, meta tags etc. All major search engines like Google, Bing and Yahoo changes their algorithm periodically and one should always update their pages according to that to stay at top or maintain there rank and this will done through SEO.
Different strategy that major search engine adopt

Over all, the basic principals are same for all search engines. The difference is occurred in result relevancy. For different search engine different factor are held. For example of Instance, Yahoo and Bing preferred on page keywords optimization while for Google links are more important for it. For Google, more a site is older, it is better while for Yahoo generally it not preferred any type of these types of criteria. So, it will take more time to rank in Google as compare to Yahoo!
