Welcome to WebmasterWorld Guest from 18.104.22.168
If I as an advertiser can find more ways to improve the targeting of my campaigns and make the spend more productive, I'm likely to increase my spending, not reduce it.
I saw a list for sale with 3000 negatives and I was rather un impressed with that number. We've got more than that and we think we are rather bad. You can also Google for the worlds largest negative list from 2006 and that's free, although it's not a one size fits all deal.
Notwithstanding that, it's a very neat idea, so I am happy to send you my email address and you can forward them on shorebreak! ;-)
I came out of retirement this month, and you have just made my day with a ststement like that.
Do you spend a long time getting negatives then? Does it really help push up the ctr?
It would be great if Google would let you know what people searched for that didn't click your add. Or do they already do this? Is this where they get their negative suggestions from?
read about both the neg keyword tool, and how to pluck negs from the records of searches, here:
hint, do both.
Of course if advertisers worked collectively then collective bargaining power (and resulting shifts in pricing) would follow.
Lots of examples of this happening throughout human history.
I recall looking at the bid gaps in Yahoo's old interface and thinking along a similar line.
However it is probably against the TOS.
