While website designing, your web pages are either designed as dynamic or static. Essentially, static web pages are those on your site that send exactly the same response to every search request. On the other hand, dynamic pages are most often customized to offer some form of personalization in the response displayed to the end customer.

Dynamic pages are obviously beneficial, and although search engines may be able to index some of them, generally the pure volume alone is an inhibiting factor to most of the major search engines in the process of search engine optimization.

In a entirely dynamic website, all web contents are stored in a database and assembled into a web page when the page is requested. The dynamic site is essential when frequent change in website content is essential and also to reduce maintenance of the site for the users who do not know HTML. In dynamic websites when the content is retrieved it is merged with a template that provides components that are common to the whole site or sub sections of the site and also includes components that control the style of presentation for the user entered data.
