Can I label the link units like this? Look at the right hand side - I labelled it Resources basically. http://cutedogsblog.blogspot.com/ thx
No. That is "falsely labeling" your ads and is deceiving the viewer. You can only label your ads two things: "Advertisement" or "Sponsors". Everything else will get you a stern warning from Adsense. Any type of warning on your account will mean your account gets red flagged as a potential problem, and any subsequent violation, no matter how small, will get you banned.
'Fraid not. It's either just "Sponsors" or "Advertisement". They are very clear about it in their TOS.
