Is AdSense text ads for Cpc ? and graphic ads for CPM ? right ? Can I setup running graphic ads always to promote CPM earning ?
most image and text ads are cpc.an advertiser can choose either cpm or cpc for text and image. "all image ads are cpm" is a myth. for a cpm ad to show they have to out bid the ecpm.
As long as your traffic is legit and you have a good number of visits and impressions, no need to worry about these things...
Get it Clear-- CPC : Cost Per Click - These ads are paid per click basis CPM : Cost Per Impressions - These ads are paid per Impression basis
