Custom review links allow you to choose which sites you want to generate reviews on.
Having multiple review links is important because most review sites are user-based platforms which means that someone has to have an account in order to leave a review on the site. For example, someone without a Google account cannot leave a review on Google My Business.
From your Partner Portal, login to a Location Dashboard.
On the left hand side click "Reviews" then click the "Settings" tab.
The top setting is "Review Custom Links" where you are able to add links to review sites where you want your customers to leave reviews. To do this, click "Add More".
After you scroll down and click "Add More", a menu drops down to choose which site you want to connect for reviews. To choose sites, click on the "Choose a Site" and paste your custom URL and click "Save".
Note: If the site you'd like to choose to connect is not one of the choices, choose "Other" from the drop-down menu. Once choosing "Other", you will be prompted to enter the site name, the URL, and upload an icon if you'd like.
