I am currently promoting a website which is doing quite well. Check this thread if interested. I was basically link begging, but I would only get a reply from maybe 3-4% of emails I sent to webmasters. Now I'm thinking of offering money for links (Asking webmasters to link to me and pay for referals. Great for SEO+ traffic+looks whitehat). I am thinking of paying them per every legit visit from their website or a flat rate. Their websites look like shit, but still rank for my keywords. I'm ranking #10, they are 20+ but if I get links from them I could rank #5-6 which will bring huge traffic. How should I go about doing this? Just send an email explaining what I want to do? Also how much should I pay?
