That’s just it though — when I type in an exact name, it may not even show up in the first couple screen-scrolls of results. I can easily see many potential customers just giving up after a page or so and assuming that the app isn’t in the store, especially since Apple is known to pull apps for various reasons.

This means that even if something outside the store mentions your app, you’d better hope they included a direct link to the store and not just the name.
