If you are looking to develope a website's Content Management System or CMS that will be search-engine friendly, then look no further than open-source Drupal CMS. Key features of Drupal power this search-engine friendly CMS from the crowd of other systems such as Joomla, WordPress or the Plone.

Here are the key features demystified for you:

Optimized URL control: Have a complete control over your URL structure with Drupal. This is where Drupal scores past WordPress. Each node in Drupal can be given a URL alias, thereby giving you a greater control. Joomla, although has made a considerable progress in this field - but, still lacks the control and functionality over the parameters guiding the URL.

Advanced Content types and views: You can create custom content without writing tedious programmes. You are able to save newer versions of your web pages every time they are edited. The ease with which you can modify the web pages using Drupal makes the entire process clean and fast.

Better Editing and revision control: The built-in version control in Drupal CMS enables you in reverting back to the previous versions of the pages. This is because Drupal saves the pages every time they are updated. You are thus able to bring in new elements to your page and remove them if they don't work out to your expectations. Although WordPress is pretty good for a simple website, one should look forward to Drupal, the moment he wants to upgrade the website.

Powerful Categorization System: Many people say that Drupal has a "vocabulary" that is limited to certain content types. But they also believe the entire system to be amazingly flexible. While one can use free keywords for certain type of contents such as blogs and products, other content such as news items can only use a limited number of keywords. This, along with other features facilitate you in carrying out a thorough SEO campaign.

Multi-User management: Not only are you able to optimize your website but you are also able to create a platform where the whole community of target audience can participate. You can create and customize user-roles and access levels, thus sharing what you want, with whom you want, and whenever you want!

Excellent Knowledge-base: Â There are official handbooks, massive API references, huge number of tutorials, and forums where people can quickly grab insights into the system. As Drupal is based on PHP, many developers find it friendlier than other CMS such as Plone which, although is powerful, but demand certain server requirements and a thorough knowledge of Python.
