WordPress is such an extensive system, that you’re quite likely to get different answers to this question from different types of users. Some users will tell you all about what WordPress can do for them as authors. Others will focus on its commerce capabilities.
In my own work, I tend to interface with three types of WordPress consumers: Owners (project leadership), users (the folks who interact with WordPress while creating content and communicating with target audiences), and geeks (designers, developers, infrastructure engineers, etc). And these are the features I’ve found the above care about most:
- Flexibility. Whatever the mission of your project, WordPress can be used to great effect. You can create simple sites for personal interests or community missions, sites for your business that can market and sell, showcase sites, and even sophisticated portals or social destinations.
- Security. Manage users intelligently, granting only the capabilities you actually need them to have.
- Discussion. Interact with your target audience with built-in comments.
- Multilingual. WordPress is available in more than 70 languages!
- SEO. WordPress is optimized for SEO and can be easily extended in this regard with plugins that add SEO guidance and additional features.
- Simplicity. Most WordPress features are very easy to use. This includes content editors that are easier to master than most office productivity applications, a navigation system that elegantly makes every feature you need easy to find, and plentiful online help.
- Media. Manage media with ease, using drag and drop interfaces for adding media content to your own online library. Then, whenever you need library content to add to a post or page, use the simple tools in your editor to add your media in any size that works for you.
- Themes and Plugins. Choose from tens of thousands of free downloads in the WordPress repository: Themes you can use to change the look and feel of your site, and plugins you can use to add functionality to the site.
- Standards. WordPress generates standards complaint code, and the platform is dedicated to evolving with the standards as required to help you future proof your creations.
- Development tools. Build your own custom themes and plugins by leveraging hundreds of intelligent functions and hooks that give you deep access to the WordPress Page Lifecycle.
- Custom content types. Build your own containers with Custom Post Types, Custom Taxonomies, and Custom Metadata.
- REST API. WordPress data type endpoints for remote interactions using JSON payloads.
- Installation and deployment. Create and push your project with ease in a wide variety of environments.
And for all three of the above, there is at least one more critical feature to love: Community. As the most widely used web development platform in the world, WordPress sports a vibrant and active community of helpful guides that can help extricate you from the toughest of spots.
If you’re researching WordPress for your next project, don’t stop here. As mentioned above, different folks get different things out of WordPress. Ask around.
