If you have an android app for your business or services along with a website, Google now allows you to connect both the app & the website. This helps users searching on their smartphones & tablets to be directed to the respective app content. Once the users have installed the app, the users will be directed to the relevant part of the app. Many sites have already implemented this feature & Google has made it even more simpler to connect the website & app. These new features also help analyze the performance & find out the errors. The steps involved are
1) Add deep link support to your app
2) Connect your site and your app
With the normal crawling & indexing process, Google will discover app/site deep links & provide the deep links results in Search. A new feature has been added in Google Webmaster Tools to help find any issues during the app-site link. It will show you what type of errors have been detected for the app page-web page pairs & can be corrected to show correct links.
