Take it from someone who’s worked with client apps making ten times as many downloads at similar price points: if you want to be successful in the app business you need to look beyond optimizing App Store search terms. You need to be marketing and promoting your application across multiple channels to a wider audience. It does not sound like this developer was doing that, so while it is sad he has had revenue slashed in half overnight he could have avoided this kind of big hit if he was reinvesting some portion of revenue back into promoting his application.
