How to earn more royalty rate in cgtrader?

@RuYing, you have 2 models posted since last year and you have over a 100 downloads? What is your secret?
Did you fill out a payment agreement? Was it approved? Questions like this are to be sent to support@cgtrader.com.

I'm new and I want to know why I have people downloaded my models but there are 0 sales and I earned 0$ from over 100 downloads! I read somewhere that the default royalty rate is 70% , so do I have 0% royalty rate that's why my revenue from all those downloads is 0 ?? please someone answer me

If you want to earn more money you should try to make some more expensive models (price at least 30$).
Otherwise there is sufficiently high royalty rate on CGT (70-80%) so with only 1 10$ model there is no diference wheather you get 7 or 8$ from each sale. So instead of thinking about royalty rate concentrate yourself on making more models.
And this is also the best way how to earn higher royalty rate - selling expensive models, by commenting other models or for activity in forum you will earn practically nothing. So do what is important.

Or u can post more stuffs in community or reply to people to gain more reputation

Sell a ton of models, and participate in discussions. Show off your work and like other people's designs.
