If your site is running on WordPress and using the Monumetric Ads Plugin, the Monumetric Advertisement ID found under the Settings section must never be removed. This identification number is unique to your site and is required for ads to load on your site.
If you are onboarding and self-implementing, your Monetization Specialist can help you find your ID.
If your site is live, and you find this field is missing an identification number, please immediately contact emergency@monumetric.com and ask for either our team to reinsert your ID or to have it sent to you if you would prefer to add it yourself.
