Google’s political ad policy covers ads about federal elections, state-level elections, federal or state level political parties, or state-level ballot measure, initiative, or propositions. Google’s political ad policy does not extend to news content or ads for products or services, including promotional political merchandise like t-shirts.

In order to run political ads, Google requires that advertisers go through a simple verification process by filling out a form on their site, and they use that information to add a “paid for by” disclaimer onto an ad. The verification process takes 3-5 days.

Additionally, Google restricts the ways that political advertisers can target their ad campaigns. For more, see the targeting section.

All political ads and ad spending are publicly available in Google’s Transparency Report.
