Drupal is powerful, does not so much see itself as a content management system, but more as a content management framework. This means, it can be used to build any type of web application – website, E-commerce, web portal – including a content management system. To put it simply, there is nothing that can't be built in PHP (Facebook for example), that can't be built with Drupal. It's Secure Since Drupal is built as an Open Source platform,
Drupal codebase is very closely secured and secured scrutinized. Open Source means the code that powers it is freely available for anyone to look at, use, modify, and contribute to. When you make your source code available in this manner, you've to make sure it's top notch code. Since anyone can contribute to it – and thousands of people across the world do – you then get code that has thousands of pairs of eyes invigilating it at all times. Proprietary code manufacturers cannot give this guarantee, when using closed source software, you have no idea what potential security flaws are present. It's Search Engine Friendly Drupal “out of the box” is quite well optimized for search engines, especially when Drupal 7 arrived back in 2011 with RDF support enabled.
The brilliance of Drupal lies in the 20,000+ contributed modules that are available for it. When it comes to SEO there is no shortage of modules to turn something that is quite good into something that is super, such as the SEO compliance checker, SEO checklist, Global Redirect, Metatag, Search 404, XML Sitemap, and Pathauto modules to name just a few that made it onto Netmag's 20 Best Drupal Modules for SEO list. It's Cutting Edge.Drupal was the first to make responsive (base) themes available to ensure that any site could benefit from the increased user-experience that a mobile-friendly website brings with it.
In Drupal 8 all themes will be responsive by default. It was the first major CMS to adopt RDF for semantic data. Also in Drupal 8 will be the awesomeness of in-line editing if you want to change a page title, then you can do so without having to load the full edit screen; same for menu items, images, footer links, copy anything. Perhaps the biggest feature to come in Drupal 8 will be the configuration in code aspect, so no longer will configuration be stored in a database, from now on the only thing to be placed in your content management system's database is non other than content! It's Free Drupal is 100% free. You do not pay single penny for it. You do not pay a licence fee to use it. This means anyone can download it and build a website as complex as.
