You're the one choosing this. You can either set a CPC by yourself or choose a CPM pricing based model which simply means that for each time your ad is shown a thousand times on the content network you pay a fixed amount you had set beforehand. This is pretty good if you have a high CTR on your ads because if you set your bid at 0.25/1000 impressions and get say more than 25 clicks then you just got super-cheap clicks (less than 1 cent/click) which is pretty cool.
I just want to see the approximate difference between between the bid amount for the search and content network. Adwords used to display the approximate CPC to reach #1, but I haven't used my Adwords account for so long I don't recall how to pull that info up or even if it's possible anymore. Thus the question. Thanks
