Half Page

Half Page ads are 300x600 ad units. This ad size allows advertisers to offer users richer content and a large space to display that on. Half page units, according to Google, have “the fastest growing sizes by impressions and is indicative of a trend where publishers are offering more visually impactful ad sizes that are preferred by brand advertisers.”
