Weve been helping users discover relevant content from Android apps in Google search results for a while now. Starting today, were bringing App Indexing to iOS apps as well. This means users on both Android and iOS will be able to open mobile app content straight from Google Search.
Indexed links from an initial group of apps weve been working with will begin appearing on iOS in search results both in the Google App and Chrome for signed-in users globally in the coming weeks:
While App Indexing for iOS is launching with a small group of test partners initially, were working to make this technology available to more app developers as soon as possible. In the meantime, here are the steps to get a head start on App Indexing for iOS:
If you happen to be attending Google I/O this week, stop by our talk titled Get your app in the Google index to learn more about App Indexing. Youll also find detailed documentation on App Indexing for iOS at g.co/AppIndexing. If youve got more questions, drop by our Webmaster help forum.
