Hi All,
We are developing tools for Amazon FBA sellers and we are about to launch a very cool keyword research tool at http://amzjet.com. How would you guys promote it? Any good traffic sources that you can recommend for Amazon FBA? Does anyone, maybe, know some affiliates with that kind of traffic?
We sell on Amazon ourselves and we developed those tools for our internal use. Since we already did the heavy lifting to develop some cool algorithms and collect gigabytes of data, we decided why not to share it with the community 
Hello,
you have a few obvious, and some less obvious choices to promote your product.
Here are a few ideas for you :
- adwords by using related KWs, same with bing etc ...
- facebook - target interests that relate to your product - online advertising, online marketing ... the best would be to get the data from a FB group that groups people selling on amazon and build lookalike audience from that - not sure if you have access to such data though
- forums - like this one, if you don't just go there to spam your product, most will let you announce it
- FB groups, join related groups and post a link to your product, if their rules allow it
- reddits or any other online communities that are built around the same subject
- email lists - if you can get in touch with someone who has a related email list, that would be perfect match
- bloggers - many people blog about making money online, check which ones are amazon focused and get in touch with them, try to get a review of your tool published, pay for a promo article or buy a banner spot on their blogs
... there are many more of course, but these should keep you busy for a while 
Thanks a lot for your input, matuloo! That's a great and a very detailed list. I really appreciate it.
