Facebook domain verification helps Facebook know you are the genuine owner of your website.
To begin please sign-up/log-in to Meta Business Manager at: https://business.facebook.com/latest/settings/domains
Once you've completed the initial set-up select the Add Domain option and follow the process to add your domain.
Next you will be provided with the meta-tag to be added to your website.
Now go to the Website -> Settings -> Tags section of your MotorDesk account and copy the meta-tag into the Facebook Site Verification field. We only need the tag ID but MotorDesk will automatically extract that from the tag.
Now save the tag and return to Meta to verify the domain.
