Promotions - HIGH IMPACT
Some promotion networks suck, but some are great. I was lucky enough to get featured as an Openfeint Free Game of the Day and it was awesome for my app. I’m doing other promotions and you definitely see a spike when you get released on these networks. Your best bet is to Google “free app promotions” and contact the teams to get pricing. You can expect to pay anywhere from $300 – $25,000 to be featured for a day. This will get you on their website, app, and social networks. It can be enormous for growing your user base.
If you’re looking to spend some money and get your downloads juiced, this is a good option.
