Im sure a lot of this has been covered all over this board .. but here goes:
I havent been working with Adwords for a couple of year but just started about 24 hours ago. Started a campaign with a couple of groups - 1 group/ad pointing to the home page for keywords very specific to the landing page and the sites overall theme. 2nd group pointing to an internal page - but again very relevant to the ad and keywords.
Minimum bid was fifteen cents on all kw and ads. All of these ran for what seems like approx 24 hours. Then as Im adding more keywords and ads today for more internal pages ... all of the min bids more than doubled. All ads turned off except one that I had already increased because of its relevancy.
Here is the CTR I got over the 24 hours --> 2.19%.. googles cpm on this was $3.40 ..
What did the algo not like about my ads ? Bounce Rate? CTR and CPM too low?
