I’ve an important information to market your game !
We know how the +1 button can be important !
But, if you link to the classic play store link (play.google.com…), this +1 will not count for the main description page (and will not count for the SEO too) !
The tip :
Instead of https://play.google.com/ use https://market.android.com/ !
The GOOD link :
for my game, I should use the “market.android” link to my +1 button or to my Google+ posts :
Just like this : https://market.android.com/details?id=com.just4fun.nervous
The result of the +1 button for “market.android.com/…” :
And you can verify that if you +1 it, the app description will be +1 too !
The BAD link :
Using the classic link, it’s NOT the case (you can the count is different)
The result of the +1 button for “play.google.com/…” :
