A dynamic URL is used if the content is stored in a database (database-driven) or if the website runs a script. It contains parameters or characters such as ?, =, &. Dynamic URLS are usually used by sites which require regular updates and changes in the content such as forums and online shops. An example of this type of URL is: http://www.loserhq.com/shop.html?page=shop.product_details&category_id=6&flypage=flypage.tpl&product_id=8.

A static URL is used when pages are hard-coded. It does not change and does not have parameters or variable strings that are usually present in a dynamic URL. http://www.loserhq.com/about.html is an example of a static URL.
