I really wish Furaffinity had community tagging. There are so many great artists that I see who don't take advantage of the tagging system, and they get lost in the noise because of it. People can't like and comment if they don't find it.
Also, the best thing you can do for an artist is comment and fav. It boosts it's popularity, and it will sometimes work it's way into the meta data and come up in non-@keyword searches.

I've also started to phrase my comments so they get picked up by the meta-data... Like:
"Oh wow, what a cute chubby pig boy! I love the chastity cage between his legs, and he's getting pounded by such a hot dilf wolf!"
This adds dilf, wolf, pig, chubby, chastity, pounded, and boy all into the meta data.
So if someone searches:
Dilf wolf pig
It might come up. The process isn't instant, like with keywords, it seems to do an update on the comment data occasionally.
