I have a campaign with a lot of kw's, some kw's within this campaign showed a horrible CTR but a lot of impressions so I decided to take those kw's out and build some relevant ads in a new campaign. This new campaign is active, daily budget is sufficient and all looks well but the ads don't show up at all in the serps. I increased max CPC but it has no effect. I think the kw's in the new campaign somehow interfere with my kw's in the other campaigns. Is this a possibility? How can I find which kw's interfere (I have thousands)?
