You might be wondering why you even need custom fields in the first place.

For example, if you want to post an event on your WordPress site, couldn’t you just put all that information as regular text in the WordPress editor?

Well, yes, you could. But using custom fields is a better approach for a few reasons:

• Easier input — rather than typing things from scratch, a well-laid out custom field group will make it much easier to input data. For example, instead of typing a date, you can just select the date from a date picker.
• Consistency — the information you enter in your custom fields will always display according to your setup, which means it’ll be consistent across your entire site.
• Easy updates and maintenance — if you want to change something about how that information displays in the future, you can just update one thing rather than having to edit each post individually.
