Google's AdSense blog features a post announcing that AdSense ads can now be used with Google Page Creator, the page-building app released earlier this year. David Jones from AdSense Publisher Support outlines the process for inserting AdSense code into Page Creator - which involves editing the HTML code, and is thus more challenging for newbies than the point-and-click AdSense insertion tools within Blogger. If you want to place AdSense ads on a free Google-hosted site, Page Creator's running a poor second.
There had to be a universal expectation that Google would ultimately allow users to monetize PageCreator pages withAdSense. But let's face it, Page Creator is a novelty act rather than a serious site building application. There are hints that its ultimate goal is to provide a front end on GDrive storage facilities (the same product manager works with both projects). Nonetheless, if you've built stuff on googlepages.com, now you can monetize it.
The flip side is that it's slightly more difficult for Made-for-AdSense robot sites to insert the AdSense code. The fact that GooglePages is still open only to Gmail users (unless they changed that)vwill probably serve as a braking mechanism on potential mischief.
