I don't pay attention to the layout of ADsense AD's often but I noticed something today. Usually an AD is set up in this format....
Title of The AD Underlined
Then this would start the description of the AD.
Today I notice this....
Title of The AD Underlined And The Description Continues So It Looks Like Content On My Website.
This probably isn't new but I just noticed it and my CTR seems to be up the last few days.
