Google continues to test the placement and location of the Google logo within the AdSense Ads. Let me count for you the times we reported these minor changes:

• Google Trying Google Logo on AdSense Ads, December 11, 2006
• Google Confirms AdSense Google Logo Test, December 12, 2006
• Google Tests New AdSense Logo Format Once Again, March 15, 2007
• Google Test Google Logo on AdSense at Top Left, March 21, 2007
• New Google Logo on AdSense Now Official, April 5, 2007

Those are the times I found I wrote about it and trust me, there are many times where I decided not to report even smaller changes. In any event, Google is testing yet another location for the Google logo.

As reported at a DigitalPoint Forums thread, Google is testing the logo in the center bottom position of the Google AdSense ads. Here is a screen capture taken from the forum thread, I added the arrow:

Just one more Google logo placement test in those AdSense ads.
