Google AdSense Adds New Half Page Ad Unit Sized 300×600

Google announced the addition of a new ad unit, their largest ad unit to date, sized at 300×600 pixels.

The new ad unit is commonly referred to as a half page unit, which Google is calling “brand friendly” ad units.

Google said this ad size is one of the “top requests from publishers” last year.

Google’s display ad study show that this ad unit is one of the fastest growing sizes by impressions.

When publishers first place these ad units on their sites, you will notice a “large number of text ads in these placements,” Google said. But over time Google will fill those ad spots with “wide range of text and display ad inventory.”
