Does anybody know how google app indexing works for iOS with new implementation via universal links? As I understand from https://developers.google.com/app-indexing/ios/app
Google App Indexing documentation for iOS 9 serves iOS universal links from Google Search in Safari. App Indexing for iOS versions 7 and 8 is now deprecated and no longer available for new integrations
But indexing mechanism is not clear. How we can add links that can be opened in app to google search? The only action from app-side is registering of app with:
[[GSDAppIndexing sharedInstance] registerApp:your iTunes ID];
There are no announcement of app index objects as for Android: https://developers.google.com/app-indexing/android/publish
So where we can add links for indexing? Before iOS 9 custom URL scheme was used to help google engine find site content for iOS apps:
<html>
<head>
...
<link rel="alternate" href="ios-app://{itunes_id}/{scheme}/{host_path}" />
...
</head>
Should we still use it for iOS 9?
Should we use custom scheme
gsd-{ourscheme} for indexing?
