As Internet user base started to grow, website owners started to make web site more and more attractive and user friendly. The most important thing to keep in mind is each webpage is not a separate file but is created when a user performs some activity.  Lets see what exactly dynamic site is! Unlike the normal HTML website where The content of static pages doesn’t change unless you actually code the changes into your HTML file: open the file, edit the content, save the file, and upload it to the server. All search engine spiders can index static Web pages. Dynamic web page is a template that displays specific information in response to queries. The database is connected to the web site and the response is generated through the connected database only. These sites are easy to update for webmaster. Since it is directly connected to database, the change in database reflects all the pages. It is much simpler than normal HTML pages, where you need to change the desired content in each and every page.

For the marketer, the creation of new pages or updates to existing pages is done by either making adjustments to information in the database or, when it comes to the site’s visual presentation, may mean adjustments to one or a few template pages. Of course one has to make web site like that only, but problem started when these beautiful, content rich sites failed to rank higher in search engines.

But the problem lies in its advantage itself. As studied earlier, dynamic page executes on query. Users send queries through search engines or they are already be coded into a link on the page. But a search engine spider doesn’t know to use your search function – or what questions to ask. Dynamic scripts often need certain information before they can return the page content: cookie data, session id, or a query string are common requirements. Spiders usually stop indexing a dynamic site because they can’t answer the question.
