Microsoft has rolled out a new feature for Bing that allows you to link your Windows Phone or Windows Store app to your website, via the Bing Webmaster Tools website. This new feature allows those who search for your website to see a link to your official app.
"Bing Webmaster Tools will be your interface to linking your website to your app. Bing App Linking lets you connect your app to your web site so that search results for the top level of your web site include a link to your app. If you implement deep linking, search results for pages within your web site will include deep links to targets inside your app," Microsoft stated in an official blog post.
This feature is part of Microsoft's Connected Sites concept, allowing you to connect official social media pages and have them associated with your website. Now you can associate your app to your site!
