Since my other online projects are at a stable level now i'm considering to try something new Since, i have about 100 blogs, everyone of them on his own domain, with 100 to 2000 posts per blog (the most of them nice long articles) im thinking about selling link spots on them. The PR varies from 0 to 3. Every blog is following one or few close subjects so each of them is pretty much targeted to a single niche. So, i can easily offer site-wide links. The only drawback i see is that the most of them are on the same IP. So, considering that, what kind of money will be worth one site-wide link per month or a permanent one. Also since im totally new in that business any advices or directions will be highly appreciated
