Wix Studio: Requesting a Review from a Client in the Wix Marketplace
Once you've submitted a completed project for a client through the Wix Marketplace, they'll get an email asking them to review your work. When your clients post a review, it's displayed on your agency profile for other potential clients to see. The more good reviews you get, the better your profile looks. If your client hasn't left a review, you can send them a link to fill out the review form.
To request a review from your client:
Go to Marketplace Overview in your Wix Studio workspace.
Click the Projects tab.
Hover over the relevant project and click View.
Tip: Use the Filter by status drop-down and select Completed to see all of your completed projects.
Click Copy review link under Completed project to copy the link to your clipboard.
Send the link to your client.

Notes:
Your client must be logged into their Wix account to view and submit the review form.
Currently, it's not possible to receive reviews from clients who did not come from the Wix Marketplace. If this is a feature you would like to have, you can vote for it here.
