Developers say the key to succeeding on the App Store is to appear on the lists of top-ranked apps that Apple compiles. The 25 most downloaded apps appear on the first page of the store when someone accesses the site from their iPhone. People also find apps through keyword searches or by browsing categories.
"If it appears in the top 100, then everybody will see it," said Vijay Chattha, head of VSC Consulting, a San Francisco marketing firm that is launching a business to help iPhone app developers promote their wares.
