Seemingly mysterious changes, experiments or similar are underway with Google Adsense and reports are starting to emerge about the changes.
Paul Short at Bloglogic reports that he has seen a change to the Google Adsense Link Unit, and has a screen shot to prove it.
Darren Rowse at Problogger has reported icons appearing in standard to across (468×60) Google adsense ads, and also has a screen shot.
I’โฌโขve not seen any changes personally, put there are definite changes to the layout within Google Adsense itself, with the Ad Setting pages now left cantered, possibly in preparation for further changes.
