Visitors have the possibility to write a review for a product. By default, all reviews need to be checked by ourselves first in order to prevent wrong information to appear and to prevent spam on the page (bots are likely to try to fill in the form, even with Recaptcha).
Log in to the backend of Magento
Go to Marketing > User Content > All Reviews
Here you can find an overview of all product reviews, approved, pending and not approved
Approved reviews are already visible on the webshop
Not approved reviews are already checked by you or your colleague and has been disapproved
Pending reviews are new and need to be checked
Click on Edit
Read the review and if you are done checking, you can choose a new Status
Then press Save Review
If you want to enter product reviews yourself, you need to enter them in the frontend and approve it in the backend.
