Why do many people ignore the fact that creatives are the most important thing? Many people think that having a nice store is the key. But what's the point if nobody sees it?
Concentrate your skills on learning to create creatives with structure, system & marketing. Simply uploading something and thinking it will make sales worked in 2015.
Structure your creatives like this (example):
1. before/after
2. intro product
3. product demo
4. benefits
5. buyer experience
6. desired result
BUT the product is the most important thing as well. You can't sell something to somebody if they don't want it. Think like this: You will never sell a burger to a vegan person !
