We're trying it. Can't say yet how it's going, because our ads only started this morning - and I'm giving us a minute budget of $1 for testing it. ;) Thus far, we've spent nine cents for 108 impressions and 0 views. Neither good, nor bad, IMHO.
I'm really not certain about the keywords...I read in Site Help that some of the keywords cost more than others, but I have no clue as to which ones that might be! (The posters didn't elaborate, and I didn't scan their shops for clues, either.)
Here's our keyword-to-impression break down:
rug 44
rag rug 19
shirt 15
tee shirt 6
camo 4
burgundy 4
navy 3
upcycled 3
rainbow 2
autumn 1
home decor 1
orange 1
I just edited our ads to nix the color keywords - I'm quite certain a shopper won't click on our rugs when they are running, say, an "orange" search because orange is simply not a dominate color in any of our rag rugs. And from what I can tell, from searches of my own, search ads are NOT pulling with relevancy. For example, I did a search for "blue rug" but what items popped up in the Search Ads were NOT blue. They were white, black, and everything else BUT blue. Go figure.
Hope this helps a little. ;)
