This is the simplest way I can explain how to succeed with AVS...

Treat your AVS hub just like you would treat any other paysite. Essentially every new gallery you submit is an update to your 'paysite'. The Premium galleries you submit should be a high-end update... brand new content, a large series or exclusive content. Older content, solos, boring shoots, small sets etc. should be used as your regular updates.

The regular updates send more traffic and you should always try to filter that traffic back to your hub where you can try to convert them to a Premium membership with your hotter/newer content.

That, in a nutshell, is how to succeed with AVS.
