If your site has been disapproved or is missing relevant information, you'll need to add this in order to advertise on Google. This policy is split into 2 requirements:
1. Missing contact information - providing at least 2 of the 3 contact points (email address, physical address, or phone number). Contact forms do not suffice.
2. Missing available payment methods - listing the available payment methods before checkout. This can either be in text or the actual card logos.
We recommend adding this relevant information in the footer of your site. It's 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.
