Before we get on with explaining the intricacies of Web 2.0, let's first understand the meaning of Web 2.0. Web 2.0 is the second generation of web development and design whose main function is to facilitate communication, information sharing and collaboration on the World Wide Web. Web 2.0 concepts have led to the development of web based communities like hosted services and applications like social networking sites, video ? sharing sites, wikis, blogs and so on.

When we talk about search engine optimization, whether it is general optimization or Web 2.0 optimization. We take into account some factors which help the target audience to rush towards a certain website. To optimize a site in the correct fashion we have to first learn how a search engine behaves. The search engine uses three main parts for searching for a keyword/key phrase. These parts are: The Spider, The Index and The Query.

The Spider or the crawler indexes the text on the web. Its function is similar to that of Firefox or Microsoft Explorer which search for the required pages when a URL is typed. The main target of the crawlers is the Content and the URL's from which the links come. A spider looks for links as it leads to more web pages or more content thereby increasing the searchibility of the website. You can also get your website crawled by search engines by running a campaign or any other optimization technique like social networking etc.

The Index software has the function of storing everything which the crawler finds. It then systematically scores them as per the level of importance, based upon the searches of the users.

The Query software is the one where ?we? look for certain things or data. Generally known as ?search? in all the major search engines, this is the one which actually helps in getting the page ranking of a website.

In Web 2.0 optimization, the same procedure is used. The difference lies in the criteria. When a Web2.0 search engine looks for a site then it looks for certain standards which have to be matched for that site to be called as Web 2.0 optimized website. Some of the famous Web2.0 optimized sites are flickr, orkut, You Tube, blogs, Google AD sense, Wikipedia and scribd.
