Does anyone know the significance of the
mtparameter in App Store Links?
It seems that any value will work, like
Apple designates a number of different Media Types (mt values):
1 Music 2 Podcasts 3 Audiobooks 4 TV Shows 5 Music Videos 6 Movies 7 iPod Games 8 Mobile Software Applications 9 Ringtones 10 iTunes U 11 E-Books 12 Desktop Apps
So, to answer your question, the “mt=8” in iTunes links simply identifies it as being of type ‘Mobile Software Applications’.
