You'll need the following ad sizes to access inventory on the general web. Learn more about ad creation.
Driving optimal campaign performance means balancing reach and performance.
The medium rectangle, leaderboard, and wide skyscraper ad sizes are the most widely supported ad sizes and make up over 80% of available inventory. With so much inventory, impressions for these ad types tend to be low-cost.
Where your ads appear
Medium rectangle ads typically appear in-line or to the right of site content.
Leaderboard ads typically appear at the top of the page.
Wide skyscraper ads typically appear along the left or right margins of the page.
Mobile leaderboard ads drive clicks. While conversions don't always take place on mobile devices, mobile ads play an important role in your customer journey by helping you reach visitors and spread brand awareness.
Mobile leaderboard ads appear in both mobile web browsers as well as in-app.
Native ads appear in a format native to the site they're on and tend to drive more clicks. Learn more about Native Ads.
Large rectangle and billboard ads are difficult to miss and can help you make a big impact on your potential customers. Campaigns that include these two ad sizes perform extremely well in click and conversion performance metrics (CPC and CPA).
The downside of these larger ad formats is their cost (higher CPM). When supply is limited, we have to bid higher to win the ad space. Even so, the potential increase in visibility, CPC, and CPA can make this ad size worth the premium.
We recommend big, bold, and beautiful imagery for this ad format.
Large rectangles appear to the right or left of page content.
Billboard ads typically appear at the top of the page.
