95% of indie games are not profitable.
Emmy Jonassen shares facts and scary tales about marketing indie games in this talk she gave at Konsoll 2013. It’s worth watching and has a ton of tidbits of knowledge that can help you promote your game.
I wish I had watched this before we launched AstroDoge. Some of what she talked about we have already done, for example the proper landing page to YouTube trailers we created ahead of time for the launch. To be honest, the hardest part of all of the indie game marketing I’ver ever done is the social media aspect.
Edit: Emmy just posted a template for a great press release page.
