I'm having problems with QS as well. I don't understand why they're being so strict, I guess they want to try to make more money from raising bids. I was running a campaign on Yahoo and making about $3K a month. I brought it to Google and I can't get past the QS. Even on some keywords where the QS is great, there's still no traffic which I don't understand since according to SEObook.com those search terms are getting more traffic on google than yahoo.
I'm even making a few dollars here and there from MSN and ask.com. Yet, I can't make anything with Google. It's pissing me off since I could be making much more money, as I'm exclusive to this offer and the only affiliate running this offer for the merchant.
I've tried a few different landing pages, I've even had content written and created a mini-site with an about, privacy, etc.. to see if that would help and nothing is working. The only thing I haven't done is what everybody says to raise my bids high for a while and drop the bids slowly, but I'm going to end up losing a bunch of money which is what you're supposed to do, but I don't know if I should risk it, or how much I should lose. I remember raising the bids to a $1.00 (my payout for this offer is $2) briefly, but then I quickly ran up $50 and no conversions so I decided to change it back and haven't messed with it.
