First off, thank you so much for taking the time to help us out on Adwords. It is definitely overwhelming to say the least.
My question is on CPM bidding:
I have an image ad, on a placement for a certain website.
Originally, my budget was $5daily with a .25cent max CPM. I wasn't getting any traffic, so I tried the extreme, $3.00 Max CPM, with a budget of $15daily. The results were weird, on the day that I ran the $5 daily campaign, I received 11k impressions and when I ran the $15daily budget campaign I received 10k impressions. Why did I receive more with the lower amounts? I really don't understand the bidding. What do you think is an appropriate bid for a CPM placement image ad. Is there anyway to know the avg cost of CPM per website? Thank you!!!
