The Google Firebase APP Indexing API supports the introduction and visibility of apps in Google Search. It allows Google to index app content for purposes of exposing it in Search results. Users can easily find, install, and launch the app to access its content from their preferred devices. However, a developer's app and website must have similar HTTP/HTTPS URLs to make it possible for Google Search to crawl, index, and support the exposure of the app’s public content. Developers can deploy either the iOS SETUP or the ANDROID SETUP platform when using the Google Firebase APP Indexing API. The Android platform provides additional user friendly search functionalities that include performance rankings of URLs and the autocomplete suggestions feature.
