Because I have animals on all my pots, I get the most traffic from dog mug, cat mug, rabbit mug, animal mug, etc. I also get some from variations on 'mug' like "big coffee mug", etc.
Sometimes colors -- I think those are mostly from people looking for items for their treasuries.
Doesn't hurt to have a few "odd" specialty things -- I get a fair amount of traffic from searches for "zombie cat" or "sugar skull whatever" because I actually make those - LOL.
I was surprised how many hits I get from my name. I add it to my tags as two words frequently. Doing that used to be important to help people find you, but not sure how much it matters now since "search" is more expanded than it used to be.
