WordPress is the poster boy for blogs everywhere, but its popularity also makes it a rather generic tool. Not to worry, plugins abound to extend its functionality. For example, Advanced Custom Fields (ACF) focuses on one particular aspect - improving the expressiveness of WordPress posts and pages through metadata.
Metadata explains your WordPress content more thoroughly and accurately. ACF lets you create your own custom fields that accompany posts and pages to describe them in intricate detail. These fields can be used, for example, to describe the product that you are discussing. As metadata, these fields have the potential to be more than just description tools and boost SEO.
