So I figured I had too many keywords that were diluting the content search. I made a new ad group with only the few top CTR keywords, all broad matches except for one exact match.
Then just to make sure, I clicked the "Edit Keywords" link, then copied my entire list of keywords, pasted them into a Gmail message and then viewed it. Still, mainly my competition.
By the way, if I go to a different content site that lets you search for products and put my keywords there, it will find my ad. So how do I get Gmail to find my keywords?
