To maintain your eligibility for Google Ad Grants, your organisation must:
Link your ads to one (and only one) website domain, which should be the same one that was approved in your initial application.
Actively manage your AdWords account by logging in once a month and making at least one change to your account every 90 days.
Your ads and keywords should match your organisation’s programs and services.
Strictly commercial advertising is prohibited. If you’re promoting products or services, 100% of the proceeds must go directly to supporting your program.
Your ads must not link to pages that are primarily composed of links to other websites.
Your ads may not offer financial products (like mortgages or credit cards), nor can they request donations of cars, boats, or other property.
Your site can’t display Google AdSense ads or affiliate advertising links.
Ad Grantees found in violation of any of these guidelines are subject to removal from the program. Google reserves the right to grant or deny an organisation's application or participation at any time, for any reason.
These guidelines are taken from Google, 2016.
