Microsoft has been slowly adding features to Marketplace. The latest is the ability for developers to link directly to the detail page of their application either in the web-based Marketplace or the on-device version, both of which will allow the purchase of software with only one more click.
Deeplinking to the Marketplace website is perfect for email marketing, or for telling users who come to a website how to find Windows Phone 6 apps.
Deeplinking to the smartphone client is even more powerful because one can embed the link within an app. When a user clicks on a client deeplink it will open the marketplace client directly to the details page of the linked application, providing a great way to help users try new products, or to convert free trial downloads into paid transactions.
Another useful feature is that deeplinks will always point to the latest published version of the linked apps, within a userâ€™s home market so developers will not need to go back and change your deeplinks every time they publish an update.
