URL rewriting
The URLs play a significant role inside a site. They represent the address where a certain page can be found. Having keywords inside has proven to play a significant part in the optimization of a site. This represents no real issue when dealing with static websites but when it comes to large, dynamic, database driven website things tend to get a little more complicated. Having "?" and "&" characters in the URL of your site don't offer the same benefits as a canonical URL.Regardless of the hosting type and OS used on the server your website should always use canonical URLs. We can achieve that by re-writing them and, in this way, providing you with more chances for higher rankings.
