Yes, absolutely! Doing it this way makes your custom post types completely relatable and fully compatible with standard WordPress query structures.

By turning Save Terms ON, ACF doesn’t just save a text string in a hidden meta field; it actually connects the post to WordPress’s central taxonomy table (wp_term_relationships).

Because it hooks directly into the core database architecture, you get two major benefits:

1. It native-links similar posts

When you click a tag on the front-end (e.g., a tag named “Consulting”), WordPress will automatically open its native archive loop page and show all post types that share that exact same tag (whether they are normal Posts, your custom Reviews, or your Services).

2. You can query related content easily

If you are coding a “Related Posts” or “Related Reviews” layout section at the bottom of a page, you can write a clean, high-performance WP_Query based on those shared tags.

Here is how you would pull similar posts inside your theme templates based on the tags saved by that ACF field:
