Hey Friend Some tips here ------> https://help.cgtrader.com/hc/en-us/articles/360015144737-How-to-promote-my-models-
I'm no expert here but I think when you upload a new model it takes sometime for your model to bed in as-it-were! You have to give it some time to become discoverable. As the article say spreading yourself about a bit will help to raise your search. Also there has been a lot of changes to the cgtrader site of late and something is not quite right! Just my opinion!
Again I'm no expert but I try to keep tags to single words and perhaps you have too many that are overly specific to your model and include a few which are more generic to the world of jewellery design!
Speaking of the jewellery designs remember your are competing in a very competitive field here on cgtrader and it seems like every other model upload is some sort of jewellery.
