A new initiative by mobile app search engine Quixey aims to integrate “deep linking” with standalone mobile applications. The initiative is called AppURL and would allow users to navigate between individual apps from within them, calling restaurant reviews in Yelp from within a social media app, for example. The concept of deep linking isn’t new, and there have been several efforts in the past to push it into the mainstream, but most companies using any form of deep linking have a proprietary method of doing so. AppURL aims to standardize deep linking to allow more immersive, efficient app use experiences.
