Update: Now, Google has announced new sharing options for the +1 button, which allow users to post content back to their circles. This could make the visibility factor for apps go up even more.
Google released an update for the Android Market today, adding the Google +1 button to apps. This could be a major factor for Android developers in getting their apps seen by consumers.
AndroidCentral shared the following video, which shows the button in the market:
The +1 button itself is presumably getting a lot more clicks since Google launched Google+ the social network. It's kind of become Google's version of the "like" button, and why its main purpose is to tell Google which content people like, to help improve search results, I get the feeling people are not too worried about the search aspect and are just clicking it in general. That's good for anyone trying to have their search visibility boosted.
Last week, Google announced that Android was up to 150 million devices activated.
Interestingly, a recent Nielsen report found that the top 10 Android apps account for 43% of all time spent on by Android consumers on mobile apps. Perhaps that +1 button will help some of the lesser known apps rise up.
In other Android app news, Google also just launched the Google TV add-on to the Android SDK, so developers can start designing and optimizing their apps for the TV experience.
