“Re-engagement advertising is driven by a fundamental business (and consumer) need, and Facebook, Twitter, Apple, Yahoo!, and Google are all responding with deep linking topologies that enable re-engagement. This is a relatively new development, and it’s hard to predict where it might go. But one thing’s for sure — deep linking is good for both the developer and the consumer. It’s just a better experience to go directly into the exact right place inside an app that’s already on your phone. And for marketers, deep linking enables far superior “landing pages” inside their apps, driving a conversion path that is measurable and repeatable. It’s not hard to imagine that re-engagement is the beginning of a more robust economic model for mobile, one that will re-integrate much of the goodness we created when the Web broke wide open ten or more years ago.”
