I heard that disabling Onsite Advertiser Sign-Up which removes the “Advertise on this site†link form Ad Units is good for higher click through. Have you experienced this? Webgaya.
I haven't disabled mine yet, but I think I read in another thread that it may take a day or two. Does anyone know how to tell if I have signed up any advertisers?
It depends on lot of variables like your niche,maturity of your visitors and how commercial and rich is your niche.for example. For digitalpoint its plus to show this link. But lot of other sites can experience lower ctr with displaying this link. So it depends.
up to 5% increase. i guess this because when people see the "advertise" word they would usually just ignore it.
