Thank you @BlossomJasmine! With good traffic i mean everyday 50-100+ unique previews to your items. So in this way they will promote to trending items. And if you have good author rating, the combination trending + rating is extremely easy to customers to find your item. Also you have to create unique items.
In my case i have account on vimeo, google+, youtube, reddit, facebook, page.
- my only one item - the tool kit that is unique, with a lot of functions, on top new authors trying to reach 1st place, with profile/item 5 stars rate already and most followers from all new authors.
Also if you provide video presentations to your items it will be more interesting and easily for the customers.
