Ease of Use
One of the deciding factors when using a website development program is going to be how easy it is to use. After all, for those of you who do not know how to code or only a little coding, you want something that can be leveraged to get the maximum benefit. In most instances, WordPress wins. As far as back-end use is concerned Drupal is more complicated to use. On the other hand, the CMS employed in WordPress is intuitive and straightforward to use. No coding experience will be required. The interface is such that setting up a simple website or blog, for that matter, is relatively easy. Really speaking, Drupal is more for those of you who have decent programming knowledge.
In this day and age, security is a big topic among IT professionals. And on this front, Drupal performs better. Although, some would argue that this has more to do with WordPress being a more popular and widely used tool. That may or may not be the case, but the fact is that you, the user of Drupal will be able to expose any security vulnerabilities, once found. When it comes to plugins and themes, WordPress has had issues. For all these reasons and more, security concerns are one of the top reasons why government agencies use Drupal more often.
The plugins and themes provided by WordPress is very easy to use. All it takes is drag and drop action by you, and you can turn a bland looking web page into a nice one. The WordPress website now offers over 5000 themes and over 50,000 plugins to choose from, for free! If you are willing to spend a little money, then there are even more options. In Drupals case, there may not have as many plugin options but users like the scalability option and coders like the API Features. Drupal also offers database abstraction, auto-update notification, localization, etc. These features are not quite as advanced on WordPress.
SEO is King
No talk of website building or anything related to it is complete without speaking about Search Engine Optimization (SEO). This topic is all about getting your web page a high ranking, organically. What’s interesting is that both Drupal and WordPress get high marks in this area, but they achieve it in different ways. Drupal decided to go toward the default caching route. This ensures faster load times; an important criterion to get high SEO ranking. With WordPress, they tackle the SEO ranking issue by offering you the required plugins.
Both Drupal and WordPress will not charge for downloading and using their system. However, Drupal does not have as many free themes and plugins. This means, as soon as you start buying the premium themes from Drupal, it will cost quite a bit more than WordPress. Things get worse when you get third party help to set up your web page for Drupal. This has more to do with the law of supply and demand since there are less Drupal developers available.
