Hi Enigineer,
There are a variety of ways to add value. Some webmasters position themselves as tipsters, and recommend teams that clients should bet on. Others might take a journalist point of view, and review recent games and give their opinion on the outcome. Other sites compare odds from various sportsbooks. We at Sports Interaction offer an XML odds feed for our affiliates use. By integrating this odds feed onto your site, you’ll have our odds directly available on your site. If you can get feeds from other sites, you could set up an odds comparison site for yourself, a great earner.
At Sports Interaction our affiliate managers have loads of ideas on how to add value. Drop us a line and we’ll see if we can help you out with more information.
Regards,
Tara
