eCommerce + seo + amazon

it's not necessary to be amazon, in some country people don't buy from amazon, it's another platform similar to that. so here's my plan

1. kw research for coming trend product eg iphone 6 case
2. bulk buy from China
3. post early to the platform (eg ebay.com)
4. blast tons of shitty link with product anchor

who tried this?

Would've done this but I don't have the cash to risk it. I would try this by starting with a low cost product? Or trying to rank a random ebay or amazon link of a random person and see how it goes.
