Is there a way to track marketing campaigns in the app store to find out what works and what doesn't, so you can determine which marketing techniques are actually working?
You can sign yourself up as a referrer (or seven), so that you can see which links result in the most sales

I was trying out different messages and promotions on different sites, and using bit.ly to make the links and linkshare to track installs.
Then, the number of links that we promote on facebook and twitter grew, and it got really hard to figure out exactly which links worked.
I had to build an internal tracking system for installs, because the other install tracking tools can't tie the installs with clicks on those links.
After helping out a couple of friends with the same thing, I decided to make this into a free tool for everyone. Please try it out @ Yozio (http://yoz.io)
