Was reading this on one of the mainstream boards.
Try this litlle test:
Search for "car", and note the ads.
Search for "light", and note the ads.
Search for "light" again, and note the ads.
The first search for "light" includes ads for car headlights, etc. The second search for "light" doesn't.
Almost like doing drill downs, or search within results.
I'm wondering if the false impressions are messing up my CTRs, and "
quality scores"?
