Search Engines and Directories

First of all I would like to discuss about the word “Search Engine“. There are lots of search engines on Internet where people find results for their quarries. The main question is what are the Search Engines? Actually, these Search Engines are a software programme which provides you the results for your quarries. There are 3 major search engines on Internet where usually people go for their searches. These are Google, Yahoo and MSN. Let’s talk about Google; Google is a Search Engine which has a very huge database in it. Whenever you put a keyword or keyword phrases in Google search box it brings you the most relevant result from its data base. Data base includes millions of different sites with their description.

Now the question is how the Search Engines maintain this data base. Google has its own Spiders or Robots and what actually Google do, it sends it’s Spider or Robots to crawl the information of the sites and these Spider /robots bring those information to the Search Engines. Now the second process is indexing the crawled sites. Search engines collect the information from their Spider/robots and index them as per their quality and popularity means those sites which has quality as well as popularity they will be on the top position. Usually people prefer to click on the top 10 sites that’s why sites owners always try to be on top ten.

Directories are same as Search Engines, as the Search engines has their huge database, Directories also has its own data base. But the main difference is that, Directories maintain its database in different categories. There are numbers of Directories on Internet. Some of them are paid and some are free, both of them are valuable but a paid directory helps you to get in its database soon. There are many free directories which give you instant link but most of them provide you deep links which is little bit difficult for Spider/ Robots to crawl it and to index it. But directories are most simple and most rapid method to get one way links for your site.

One of the important part of a site is its “PAGE RANK (PR)“. Page rank plays the role as a measurement unit to measure the popularity of a site. Now what is popularity, popularity is counted by the numbers of votes or links given by other sites. On that bases Google decide a site’s page rank. That’s why it is most important for a site to get more incoming links that we call “Back links” which helps to get high PR for a site. Many times it happens that we are linked with many sites but when we wants to see our back links the result will be very low. Actually the links which have quality and relevant to the site will only be counted as back links. So get those sites to be linked which are relevant to your site, having high quality and high PR.
