"Involuntary" PPA ads?

Is AdSense going PPA (at least partially) no matter what?

[loudspeaker]

There's an interesting piece of news about Google supposedly converting a certain % of AdSense CPC inventory to PPA for some sites... unless they explicitly opt out.

[searchengineland.com...]

Google sent out emails to select publishers, notifying them that a portion of their ads will be serving Google's pay per action ads.... This will only impact about 5% of a publisher's ads, plus publishers can opt out by emailing Google.

What do you make of that? First of all, it'd be nice to know if such reports are true. Second of all, if they are, is it a beginning of a mass conversion from CPC to PPA? And how do you think your earnings are going to be impacted?

First of all, it'd be nice to know if such reports are true.

This was discussed here a few weeks ago in a thread on letters from Google to German publishers about a beta test of CPA ads.

Second of all, if they are, is it a beginning of a mass conversion from CPC to PPA?

No. At most, it would be a product extension, like site-targeted CPM ads have been. Google wouldn't be foolish enough to discard its core AdSense product (a product that brings in nearly a billion dollars per year).
