Today we’ve updated the AdMob engineering blog with two new posts.  The first of these two posts continues an earlier discussion about ad serving mechanics for the mobile web.  The earlier post in the series talked about how mobile ads are retrieved, whereas today’s post motivates why ad retrieval for mobile sometimes needs to be different than it is for the web.

Our second post today discusses AdMob’s new ad creation user interface and describes some of the techniques that went into building it.  We also offer up a hint at the first of several upcoming contributions back to the open source community, an extension to the EXT JS AJAX library’s tree widget.
