I wish to direct one of my domains directly an affiliate on clickbank. Is this possible and how can I do it? Which affiliate link do I use from clickbank? I used one and shows I have over 2500 clicks so far but no sales.
You should just be able to redirect the domain to your affiliate URL. Try it and make sure it resolves and tracks.
Is that clickbank product what visitors to your site are looking for? Based on what data? With no purchases in 2500 clicks (that's not even a 0.04% conversion rate), it sounds like it's not a good fit ...
