Google Adsense takes desperate measures to promote the CPA Referrals, because probably it’s not so used, as it has a low-to-none EPC.

Some publishers received an email that announced them their contextual ads will be sometimes replaced with CPA Referrals ads, without having the possibility to opt. That’s another wrong move for Adsense and they are surely losing significant users, especially the CPC is continuously going down.

Here’s the email users are receiving:

Dear Publisher,

Your account has been selected to participate in a limited test of an exciting new targeting feature for AdSense. In the next few days we will enable cost-per-action (CPA) ads to compete in your AdSense for content ad units on a limited portion of your traffic, 5% or less of all ad impressions. These ads will look identical to your current AdSense ads, so there will be no visible changes to you or your users.

Your account has been selected because we believe that you’ll earn more by having these additional targeted, high-quality ads competing in your ad units .

Rather than generating earnings for a click or impression, you’ll be paid a larger amount for each conversion with these new ads. A user who clicks on your ad must complete an advertiser-specified action, such as a purchase or a lead, in order for you to be paid. Remember that these ads do compete with cost-per-click and cost-per-thousand impression ads, so a CPA ad will only win in an auction when we expect it to perform better than a CPC or CPM ad.

You won’t notice any change to the way that your earnings are reported. Revenue from CPA ads will appear just as any other contextually targeted ad revenue is reported.

As a reminder, all information about this test is Google Confidential Information under the applicable Google AdSense terms and conditions.

If you have any questions about this test or would like to opt out of this experiment, please email us at adsense-support@google.com.

Sincerely,

The Google AdSense Team

The best web hosting service may or may not be a cheap web hosting service, but such things don’t matter, if it delivers what it promises. With online advertising, people are much more aware of such facts. Also, thanks to services like netfirms, everyone knows the importance of online marketing and the necessity of affiliate commission for that. That means more awareness regarding sem strategies like cpc and ppi.
