Anything can be profitable if you put enough work into it. Obviously some people are going to prefer some affiliate networks over others but there are people promoting all kind of different things, including Clickbank, making 6-7 figures. Don't be afraid to go into something but just remember there are a lot of trash products on Clickbank. Make sure to promote a good one so you get more conversions and less refunds.
Update
Don't have much to update on today. I was able to get stats on how many people go from my landing page to the offer page and its about 25% of the people. I'm not sure if that's good or not could someone chime it on it? My ad ctr is around 8% and cpc around .35-.40. So I'm sending about 30 people to the product page daily after them going through my lander. I'm using a news article type landing page for now. Sadly it doesn't seem to be working. Got no conversions today. I was searching for other offers similar to the one im promoting and noticed there was one with a free trial offer rather than a purchase. I'm thinking of setting up this offer instead of my current one. Does anyone have experience offering free trials rather than products? I would be getting like 60% less per conversion but if more people sign up for it then it's worth it. Let me know if you think it's a good idea. I'm likely going to set it up anyways when I get accepted for the offer so I'll let you guys know
I'm going to stop posting pictures unless something good has happened. It's a bit of a hassle uploading and embedding it every time. Sorry for those who like my pictures!
