Both Advertisers and Website Publishers are interested in what ads perform best. While this changes over time, here is a snapshot of what is currently the best performers. We recommend that both advertisers and publishers read over this information and use it to their advantage to increase the performance of their ads and ad spots.

Size Matters

The best performing ad size is the Leaderboard (728 x 90). Coming in a close second is the Medium Rectangle (300 x 250). Both advertisers and publishers should see good performance from these banner ad sizes.

Location Matters

Where a banner ad is placed is perhaps the most important factor for maximizing the rate that visitors click on it. The best performing ad zones are placed at the top of the page. Following the top of the page is placement close to prominent content, such embedded within the text of an article. Placing ads in sidebars or away from prominent content has only mediocre performance. Finally, ads placed at the bottom of pages is the worst performing spot – we don’t recommend placing ads at the bottom of your pages.

Advertisers: Use Low Inventory Banner Ad Sizes

The most popular ad size in use by publishers is the Leaderboard (728 x 90). On the other side of the spectrum is the Rectangle (180 x 150). Create a Rectangle ad and you’ll be greatly increasing your exposure since there is currently a very low inventory of this banner ad size.

Advertisers: Support All Banner Ad Sizes

There is no penalty for submitting multiple banner ads for a specific campaign. We recommend that advertisers submit one banner ad of every size for each ad campaign. This will ensure that your ad campaign is considered for display in every ad spot across our network. If you only submit a single banner ad for your ad campaign, your ad campaign will not be considered for display for any ad zone that is not of that size! You’re losing out on impressions in this case.
