What I aim to do is charge a fee if advertisers want their free listings ranked higher so they are above the free listings in a directory.
With using NoFollow, I will be alright with Google, but just wonder if it’s allowed if I didn’t place anything on the paid listings to mention that they are paid. In other words, all I’m doing is ranking them higher, they are already in the listings, just because I get paid, they get ranked higher, so does site visitors need to know if they are paid or not as they are in the listings in anycase and are of quality and relevant to the category they are in.
No matter if someone wanted to pay for a listing to be included, I will not accept payment if the site is of poor quality and will not list it.
So instead of having sponsored listings or advertisement by each link, could I just put nothing so they look just like the other non paid listings?
Just curious?
