Toughest Niche to Monetize?

Hi all, curious about everyone's opinions of the toughest niches to monetize. Was there one niche that you thought would be a goldmine, but after you got the traffic it turns out no one is buying?

My biggest surprise lately has been the weight loss niche. I've got a site that's pulling 150+ uniques/day for a few weeks and makes no Clickbank sales. I'm thinking of moving away from CB and putting some more legit physical products up to see how those work out. It's been my biggest head-scratcher site since all of my other sites that have physical products sell pretty well. I'm also starting to think that perhaps these people looking for stuff like "easy way to lose weight" etc... are just not buyers. Anyone else run into a conversion nightmare?

This is always happening in health niche sites. I myself holding some no.1 position sites for weight loss keywords doesn't have any sales from clickbank. Might be we are missing to find suitable products i think. need to do more experiment.

Tough traffic that seeks for something "free", "torrent", "nulled", etc
Also it is difficult to monetize teens and kids cause they do not have credit cards.

I have exactly the same 'problem' I have a weight loss site that brings in a couple hundred visitors a day and hardly get any sales... I still keep it up and running but just dont promote it, I may get 1-2 sales a month... I think people have learnt to hit the gym rather then reading some e-book.

It's not the niche, but wrong keywords.

The guy who gets traffic for 'buy weight loss pills' will make money, but not the one who gets traffic for 'free weight loss tips'.

i have also same predicament as you are. i do have that is on health niche also. specifically eczema. and havent have a CB sale. some customers are always looking for a free treatments now a day.

Adult niche is very though cuz of high competition. In general - Free cpa offers convert better than trying to sell stuff imho.

Adult is tough - but weightloss and loans (money) is always hard as well - but high payout.

If your CB is not converting traffic - try adsense , if your following the TOCs.. just a thought. No need to waste all those nice clicks
