What are key features that enable a salesperson to get maximum customer attraction?

Don't sell your product , before trying it. 

Never Lie , but hustle. Don't ever underestimate the small good stuff about your product.

As Ex, ( If your selling a phone, don't only foucus of what the phone can do , go more and talk about design of the phone , or how smooth it is ) 

in the first minute of your meeting, try to know what is the valuable he have as (Car, watch, Fancy suit), talk about it a lot , and ask him questions about it and how you are admiring it
