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 - Customers need to be able to find out how to contact you on your website in at least one way. Examples include, but are not limited to, a contact us form, a link to your business profile on social media, and an email address or phone number.
We recommend adding this relevant information in the footer of your site or to your contact page. They should be easier 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.
