To be honest, I don't know the answer because Amazon won't tell us. So I do it anyway to hedge my bets. I would rather waste a few words and be sure of showing up than not bother repeating and then not showing up. Also I do try to mix and match words that mean the same thing, again to ensure covering all bases: EG: Romantic comedy, humorous romance, funny humor humour love romantic. That kind of thing.artofstu said:In the above example, you use paranormal, love, romance more than once. I was under the impression that once you use a word, you don't need to use it again, that when someone searches for a term, Amazon will pull from any of the words you've put in your keywords. This seems to be the case whenever I've done test searches using a combination of words that aren't necessarily in the same keyword group. Anyone else have an insight on this?
