Google has added multiple new formats to their AdSense Contextual Advertising Network for web publishers.
The new ads offer the ability to show only one targeted text ad at a time, intros a new, wider skyscraper, and small and big versions of their rectangle ad formats.
New formats include:
Button (125×125) – Displays 1 ad on a page
Wide Skyscraper (160 x 600) – Displays up to 5 ads on a page
Vertical Banner (120 x 240) – Displays up to 2 ads on a page
Square (250 x 250) – Displays up to 3 ads on a page
Large Rectangle (336×280) – Displays up to 4 ads on a page
and the Small Rectangle (180×150) – Displays 1 ad on a page
Google seems to be encouraging the use of ads placed with the main content of sites, which has been rumored to bring better results for publishers and advertisers.
