Hi:

This problem is not uncommon in many spaces. For ecommerce sites where there may be overlapping of search terms between product, brand, and catagory. In real estate you may have over lapping of a sort between State, County, and City.

But a couple of points.

1. If you vendor doesn't get it why stick with the vendor. If your spend is 400k, is that is a large chunk of change and you should have a vendor that is meeting your needs.

2. Google won't penalize you if you use the same search terms in multiple campaigns. What they will do is run the campaign that is bid the highest. But here is the kicker, that isn't always the case. They will run the lower CPC a certain percentage. This is all part of the Quality Score issue and mystery, and the newly announced change in QS doesn't help matters.

3. The real life saver is the geographic factor. Try to use this to the best of your advantage. You may need a larger number of local campaigns to get the volume but these clickthroughs will also tend to be more qualified and have a better chance of converting.

4. Is this B2B or B2C, is it lead generation or ecommerce, then more specific advice can be given?

5. If you are spending 400k you should be reading Perry Marshall's and Andrew Goodman's ebooks, agree with the other post.

6. I have an ebook on PPC that I helped edit. If you want a copy write me at jglogau@phr400.com
