What Are Custom Fields & Why Make Them Searchable?

WordPress custom fields allow you to store any kind of additional information (metadata) about a post or page.

WordPress adds metadata such as title, author, date, time, and more to your posts and pages. With custom fields, you can add more information about your content, and display them on your website if you wish. A lot of popular WordPress plugins and themes use custom fields to store important data.

For example, the content you enter in your WordPress SEO plugins such as All in One SEO is technically a custom field, or custom product attributes that you may add to your WooCommerce products sometimes are also custom fields.
