One of Google Ad's top benefits is its massive reach. Advertisers can easily reach billions of people across the greater web through Google search, Shopping, Maps, Gmail, YouTube, Discover, and more than 2 million different partner websites and apps. Google makes it easy for advertisers to reach all of these constantly updating placements across the web, too. Some of Google's campaign types–such as Performance Max, App, and Smart campaigns–even automatically target all of these available placements to further simplify reaching this massive audience for advertisers.
