For example I have two sites with overlapping subject area. I was wondering whether I could run two adverts side by side but going to different domains. Obviously only one advert will show at any one time for the keywords. However, if one got hit by the price hikes in keywords - would it affect both domain names. And if this is the case, surely this is not what QS is all about. One of the two sites could be much better quality than the other.
I have these two overlapping sites. They are completely different in all respects, but do have a couple of pages that are on the same topics. I get a much better ROI from the site that I think if any, Google would slam. The other site I feel is much better quality, although this particular page gets a very low ROI.
Just wondering if anyone has experience of this.
