Thanks for the comment.

With the tagging system: they would look for the "sport" tag.

(Actually it wouldn't be a tag because sport is a "top-level-tag". Instead it would be a category with a dedicated website. So the users would go on sports.listing-platform.com and then be able to select tags like "football", "soccer", etc.)

and if a user is looking for fantasy sport websites, then they would lookup the tag "fantasy-sport". The fantasy sport website would publish itself on listing-platform.com under the tag "fantasy-sport".
