Google Ads is Google's online advertising program. Using Google Ads, users can create online ads to promote their business, help sell products or services, raise awareness, and increase traffic to their website. Ads created in Google Ads may also be served by the AdMob Network and appear in mobile apps.
Linking an existing or new Google Ads account allows you to create campaigns in AdMob. You can create house ad campaigns to cross-promote your apps or set up direct sold campaigns to sell ad inventory to an advertiser. Learn more about Google Ads:
