Google has made a dramatic move in removing apps that are either non-compliant or engage in some way in the art of spam. According to Techcrunch the marketplace for Android apps has about 60,000 less titles to choose from. These titles were removed in the last couple of weeks of February, according to the tech web site. They also note that not all of these apps were removed by Google – some were likely pulled by the publishers themselves.
Google doesn't vet apps prior to publication the way that Apple does through its stringent and strict approval process, which can lead to a lot of questionable apps showing up on Google Play. But one thing Google seems to be vigilant about is deleting those apps that violate its Terms of Service, such as those that spread malware, infringe on others’ copyrights, and apps containing graphic or sexual material. Spam apps are removed the quickest because Google is pretty serious about them – there's a whole section in the ToS dedicated to those types of apps. Here's the general guidelines about apps that want to be on Google Play:
Developers are important partners in maintaining a great user experience on Google Play.
■Do not post repetitive content.
■Product descriptions should not be misleading or loaded with keywords in an attempt to manipulate ranking or relevancy in the Store’s search results.
■Developers also should not attempt to change the placement of any Product in the Store by rating an application multiple times, or by offering incentives to users to rate an application with higher or lower ratings.
■Apps that are created by an automated tool or wizard service must not be submitted to Google Play by the operator of that service on behalf of other persons.
■Do not post an app where the primary functionality is to: Drive affiliate traffic to a website or provide a webview of a website not owned or administered by you (unless you have permission from the website owner/administrator to do so)
■Do not send SMS, email, or other messages on behalf of the user without providing the user with the ability to confirm content and intended recipient.
Ultimately this is a good thing for users of Google Play because it means that they have to wade through less crappy apps when searching for something in particular, and it means they won't accidently install some app that is questionable in nature.
