We sell open source security keys: https://solokeys.com https://solokeys.com Paid: Amazon, the thing I like is that their dashboard clearly shows marketing cost and revenues, so you can very easily say whether it's worth or not. Non-paid: - Github: http://github.com/solokeys/solo http://github.com/solokeys/solo Last time I measured, we had 1% of our traffic coming from Github, and 1% of that traffic converting to a sale. This is pretty awesome I think, especially because having a baseline we can improve. We're not making any strong sale-pitch on Github, we simply put links to our store at the top and bottom of the readme. Right now we're running a crowd funding campaign, and because we knew Github was bringing high quality traffic we're advertising it there. - Twitter. This is our 2nd social in sales. We're not doing anything special, just clear profiles (personal and business) with links to the store, and clear call to actions when you tweet. - Pinterest. This is the social that bring us most clicks the the store. I know the platform very well, of course. For SoloKeys specifically the audience is not right, so there's little to zero conversions to sales, but it's good learning nevertheless. - Medium/Hackernoon. When we blog, we typically get spikes of traffic and sometimes sales. But it requires time to write posts, so it's not really as scalable as the other channels. (We're barely using Facebook, and zero Instagram, so I can't really talk about these).
