If your site has been disapproved for or is missing sufficient contact information you'll need to add this in order to advertise on Google. Below is how to fix this policy.
Missing contact information - providing at least 2 of the 3 contact points (email address, physical address, or phone number). Contact forms do not suffice. We recommend adding this relevant information in the footer of your site or to your contact page. They are easy to find, and will ensure Google can approve your website quicker.
If your campaign is disapproved for this policy, please reach out to firstname.lastname@example.org once corrected to get your campaign approved. You may also contact email@example.com with any questions or request assistance with your disapproval.
