Google announced the launch of a new ad size for AdSense ads today: the 970x90. This is a newly adopted IAB standard known as "super leaderboards".
"This larger ad size is another visually impactful placement for advertisers to promote their products and services even on wider screens," says Google AdSense software engineer Omer Gimenez and AdSense product manager Johan Land in a joint blog post.
"Please note that since the 970x90 unit is new to our network, you’ll currently see mainly text ads appearing in this format," they say. "The new super leaderboard ad unit can show up to four text ads organized in a column layout but, as with other ad sizes, the number of text ads per unit may vary per impression. When enabling image and rich media ads for this unit, display ads in the size of a 728x90 unit will be displayed initially. Over time, we expect that the inventory of image and rich media ads for the 970x90 will grow and you’ll see more full-size display ads being served."
Back in November, Google introduced the 300x600 ad unit to positive feedback. Those who wanted larger ad sizes are truly getting their wish.
