1. Make your presentation and tags spot on as possible:
Keep Google ranking in mind so make your description as complete as possible. Tell in detail about what your providing and give enough technical information. Keywords are very important so take enough time to think about them.
3. Use Pinterest, Facebook, Instagram, Behance, Twitter, Youtube, Vimeo, etc.
Having many social profiles and spend some time on them to transfer traffic from one to the others can make your network stronger, it works better with eye catching stuff but you can also provide tutorials or give something away for free and post about it.
3. Avoid making models for overcrowded category's:
Posting models that get 5000 hits when someone enters the keyword for it will land your item at page 150 or something and most people do not go past page 15. In that case your only hope is the per price filter and providing the models for 2 dollars so it shows up on page 6 or something when people use that filter.
If you manage to get sales then that works best, it brings your stuff to the front and then it gets more views.
