In a September 29, blog post on Windows Phone Developers blog, Todd Brix talks about "How Marketplace Manages Bulk App Publishing" issue -- writting that "Windows Phone Marketplace is committed to providing customers with a wide range of certified applications, increasing and curating app quality and providing a safe, reliable and convenient shopping experience."
Brix notes that the "first step we took to curb this behavior was to limit the number of apps that one developer can have certified in a single day to 20." Adding, "We're again observing a small number of developers publishing apps in bulk. Therefore, Effective Friday 9/30 we are limiting the number of apps that can be published in a single day without prior agreement to 10. This means that no more than 10 apps by the same developer will be certified per day (down from 20)."
In addition, "we'll monitor the number of apps published - not just certified - in a given day and be more proactive in correcting instances where the 10 app limit is exceeded. This may include the unpublishing of apps, and in extreme cases, temporary or permanent suspension of an offending developer's Marketplace credentials," Brix said.
Brix also shared a few related reminders:
- "Unique apps can only be published in a single category. Any duplicate apps showing up in other categories may be unpublished, per the Windows Phone Marketplace FAQ's
- When applying similar templates to multiple types of apps, we recommend differentiating apps through unique iconography, titles and other metadata to help potential customers make informed decisions about downloading apps.
- As mentioned in application certification requirement 2.10, apps must have distinct, substantial and legitimate content and purpose. Differentiation between your apps can help meet this requirement.
- There are several ways for your apps to be featured in Marketplace on the phone and now on the Web. Apps are featured by category based primarily on their number of downloads and customer reviews. The same is true for the cumulative top and free sections. The New panorama that makes up the background is algorithmic based on timing."
