in my opinion the best niches are IM and weight loss...because people always want more money so they look for new strategies...and they always want to lose more weight...
That question is WAY to general. Some people make a killing with software from clickbank while others do it in the weight loss or health niche. The "best" is depending whatever way you can drive traffic and visitors to your sites. IMO, weight loss is a very hard niche for me since i focus on SEO...and getting a weight loss site to top in Google is tough, to say it mildly. Furthermore....keep your eggs in more than one basket, dont focus on ONE product or only one niche.
I think IM is the best because there are always loads of really great products and I have found that I make more money with my IM subscriber list than my weight loss list.
Sadly there's no such thing. Let me explain -- There's around 10/20 niches in Clickbank that am I aware of/ that have pretty great conversions in targeted traffic: 1 : 40 - 1 : 60 (you first have to know your audience/ and drive targeted traffic to your landing pages). Ya know?... Without getting to know/ do your own research you can't come up with a winner. Al.
I personally think the best and most profitable niche is IM info products for beginners, 2nd to that is healthy products, such as bodybuilding, weight loss. Because there are just so much demands out there. Think about that, 10 or 15 years ago, have you seen lots of weight loss or healthy products ads on TV, now it's still going. Making money is the same, it's just now a trend is moving from physical store to internet. Just my thoughts...
I think it's all about finding the right audience first and then picking a great product in that niche second. Always find the crowd first and product second.
When I choose a clickbank product, I ask myself a few questions. What is a big problem people have (emabrassing, don't want to buy something in person etc.) Then I find a product that would match the issue. I know that may seem too simple but think about it. What is embarassing for people to deal with...these markets are huge, man boobs, yeast infections, penis enlargement....those are things people avoid talking to someone in person about...many turn to the net for their solution! That's where we come in!
