So, correct me if i'm mistaken, the only use of adding a 'personal' tag to your game, would be to wait and see if it would be given special status anytime in the future. The special status tags are the thing bringing the most views, at least in my analytics - and after the game appears on the front page in case it manages to. Because the search function doesn't seem to care about personal tags, it just seems to care about the title and subtitle.
Viewing post in How to promote your game. anyone???
Is it automatic? I mean is it possible for new tags to start appearing there on their own, whenever they become used by enough pages, or does each and every tag require a manual input, by the people behind itch.io, before it has a chance it can be found in the 'browse all tags' page. I assumed the latter, and by 'special status tags', i was referring to those tags which can be found there.
The portal would perhaps benefit from a tag search of the kind I meant, anyway. for example, for my game I considered adding an 'history' or 'historical' tag, but having no way to see which one of the two is already the most shared by the most projects, if any, I decided to stick with suggested tags, even though they were less relevant.
Far as I know it's automatic. All that admins do is mark some of them as denoting engines/tools or genres, so they can be used in more ways. And for what it's worth, the tag field on a project's edit form should have autocompletion, so you can at least see which tags and tag forms are popular enough (if not how popular exactly) and make a decision.
