- I made an identical page and put it on 2 different web servers with 2 different domain names. The one that I used for all of my google ads was getting inactive bids of $10+. The new site was running keywords for 30 cents. The landing page was exactly the same. The landing page contained affiliate links in both cases (about 50). The only difference was that it was a new domain name, that I had not used before. The landing page was not a part of my main site.
- I tried another one. The same landing page, same web server, 2 different domains. On this one, the landing page was my home page. The new domain name gave me awesome rates, but after a few days I was being penalized.
- Another user said the vanity url, if different than the landing page url, might cause the minimum bid to go up.
- I have an account with a campaign that has 50+ ad groups. They are all basically the same landing pages, just different products. Same format. As I was adding them one day, the min bids were fine. Then when I added around the 20th ad group (just guessing), the min bid shot up real high. Then the min bids for the other ad groupds shot up too a few days later. I think we might be penalized for too many ad groups.
- I found that one of my older accounts was getting good bids. If I create new ad groups in that account, I get low bids. For some reason the account as a whole also gets measured.
- My US / Global ads are being penalized, but if I advertise in the UK I get dirt cheap rates.
I will do more testing. Please feel free to post other tips.
