“Link to App Store” widget for mobile website

问题

For the past months I have found several websites using some kind of "widget".

If I open a website having this widget with my iPhone, it will display a link to the (website related) iPhone app. It looks like a simple div containing appname, rating and link. The widget even "knows" whether I have already installed the app or not.

This thing is always shown on the top of the page and looks always the same. Is there some kind of widget/API offered by Apple or who is the creator of those links? I have found nothing yet in the web about it...

Thanks for your help!

You're looking for "Smart App Banners".

Usage is as simple as adding the following meta tag to your web page's source code, specifying the Apple App Store ID some affiliate data, and even a URL scheme argument.

<meta name="apple-itunes-app" content="app-id=myAppStoreID, affiliate-data=myAffiliateData, app-argument=myURL">
