Let's say I wanted to charge 20 dollars a month for a no follow signature on a forum. How about 10 or 5 dollars a month. How much traffic justifies this price? Of course, were not talking about banners or other stuff outside of a no-follow forum signature.
Spending dollars per month will not determine the website's traffic and what is your purpose on targeting no follow signature on forum?
If a forum has a lot of traffic then people would want to access that traffic via their signature. But how much is enough for advertisers?
That depends. I think discounts would be much more effective. But that's right spending dollars per month will not determine the website's traffic.
