Search Engine and World Wide Web are indispensable; they can’t survive without each other. WWW has a huge and bulky database with the aim to provide information to its users and this job is done by search engines to provide relevant information to its users as search engines categorize this information (database of WWW) and stored it into its own database. Which supports the relevance of content?

The major objective of WWW and search engine is to provide relevant information to its users and generate some revenues from them. WWW provide a platform for a search engine to do the relevant task. For instance if a website is created then that website requires some server space to get some space in WWW or to make its existence on the internet. When WWW stores that website into its database then search engine get it from WWW and store it, in its own database. This thing is beneficial for both WWW and Search Engine

• Traffic Increased.
• Revenue generated.
• Information becomes more relevant.

Relevance of Search Engine:

Each and every search engine has its own underlying principals or core beliefs which help guide how they craft the search relevancy. While some machines automatically evolve search relevancy via genetic algorithms each major search engine still has some human input in how relevancy is calculated.

Search engines and www create a win win situation for each other, without  www search engines have no place to store its information as a result  search engines never get traffic and revenue become 0. And if revenue becomes 0 then there is no use of running the business. And only because of search engines users searches the web.
The percentage of traffic depends upon the requirement of traffic, quality of content or information that search engine include into its database.
