Dynamic websites are usually database driven websites where some parts of the content are generated by SSP(Server Side Programs) OR Middle Tier. The problem is many search engines find it very difficult in indexing dynamic websites, but there is always a solution for any problem.

Initially you need to understand why search engines are unable to read dynamically generated websites.

1. Dynamic webpages doesn’t exist on server physically.
2. They have complex URLs such as “ http://www.example.com?name=value&blabla%blabla@session_id@2226897&blabla=77″ . Special characters like “?”, “=”, “@”, “%”, “$”, “*”, “&”, “! are not understood by robots or spiders.
3. Search engines consider these dynamic website as group of never ending links.
4. Search engine crawlers will get stuck in an loop, specially if the dynamic website has session id’s.
