If you are displaying your Feefo reviews on your own site, whether it be on your own dedicated reviews page or on other pages of your site, you could be at risk of being punished for duplicate content.
This can be resolved by adding a canonical tag. Canonical tags tell Google which site is the original source of content and which is the duplicate. By declaring this to Google, it tells them to ignore the duplicate.
Please speak to your account manager to set this up for you.
