How to make money with non profitable keywords

I found lot of very low competition (easy to reach google top 3) keywords, with nice search results (10 000 - 1000 000 searches/month), but almost no relevant adsense ads, no products to sell, no relevant CPA offers etc...

How to make money with these keywords???

adsense or if there is anything that those people would be interested in, then you could use ************** or zangocash or etc.

Maybe you can try to filter that traffic to some sites in what they might be interested in and then try to monetize them

depends.You can promote incentivized offers,gateways like **************,bhcb.
If i were you,i would ask them for a survey or something (while capturing their email id)to understand the audience of these keywords demand,demogrophics.Then you can push the right offers.

What is ************** ? why stars, where is link?

it's a banned network on here... I'll PM you

Run some ppc ads on adwords and see what works. Promote cpa offers.

I usually do one of these things:

1- I'd take a good look at the top 5 sites in Google and check how they're already monetizing their sites. If what they're doing doesn't convince you ( or you see they're not doing anything, really ), go to Quantcast.com and/or Alexa and check their demographics. Then look for related offers or find other sites they're visiting, and repeat the process.

2- Offer a somewhat "general" easy email submit ( internet connection or sth.) as part of a gateway.

3- Offering a book on the subject from Amazon might work, as people tend to buy other stuff from there as well. Not my first option by any means, but sometimes it does work.

4- I'd stay away from CPM and PPI, but that's just me.

The best of luck to you.

And dude what are you waiting for ? go make some websites for that keywords, once you get traffic you'll for sure monetize it with adsense at least .. .
