I personally think it helps me read the notes by tabbing songs. Since I tab sheet music. Popularity is a big factor as well, the more views, the more likely your tab will get commented on and rated. Most of the tabs that I have that are commented/rated have 1,500+ views.
But most of all, don't worry, the longer your tabs are out there, the more people will see it.
One thing I also do is say in the tab, for those who liked the one they are viewing to click on my icon to look at my other songs. So hopefully those that view 'Love Song' by Sarah Bareilles look at my other tabs as well XD
