Adsense earning from CPM

You have ample number of page impressions but your earning shows as $0.00 because you do not have click on the google Ads. Are you disheartened? Looking for earning through page impressions only? Yes you have landed in the right place. Here I am going to discuss how to earn through page impressions. In Google Adsense programme Ads can be either cost-per-click or cost-per thousand-impression basis. When the advertisers display CPC ads only in your site, you will earn for each valid click-through on ad; You can earn cost-per-thousand-impression basis when the advertisers display CPM ads. CPM stands for "cost per 1000 impressions." The adwords advertisers set specific price per 1000 ads served. They chose particular site to run CPM ads, and pay each time their ad appears. Now the question is how do you get cost-per-thousand-impression ads. CPM ads can be either text or image ads, and are always site-targeted. CPM ads and CPC ads compete each other. You will be paid as per the highest performing ads. So your site should be good enough to get CPM ads.
Both Text and image ads can be paid on either on CPC or CPM basis. Advertisers will choose which type of ad they'd like to display - text or image. If the advertisers consider that your site is relevant for displaying image ads they will display image ads.If you chose only image Ads, You might see public service ads if there is no image ads relevant to your site content. So, I suggest to opt into both text and image ads. There by you can maximize your site’s revenue.
At present all CPM ads are site targeted, that means if an advertiser select your content as relevant to their campaign only then CPM ads will be displayed on your site. customize your Onsite Advertiser Sign-up landing page for advertiser bidding on your site.
