Yeah, that's what I usually do, but this particular campaign I'm getting a lot of traffic and my payout is low, so I'm not even breaking even. Although I think if I can delete non converting keywords, I might be able to make something from this.
There are about 2000 keywords, like you said about "eventually performing" that's what I'm confused about and don't know if I should delete them right away if they don't convert after 1 click. Due to their being 2000 keywords, I don't think I can really afford to keep a keyword after 1 click if it doesn't convert. I guess I can go through the entire campaign and just turn off non-converting keywords and just keep tweaking like this and just see what happens?
