Google has introduced a variety of new formats for video ads.

The three new formats include:

• 728×90 Leaderboard
• 120×600 Skyscraper
• 160×600 Wide Skyscraper.

Previously, video ads were only enabled for the 300×250 Medium Rectangle, the 336×280 Large Rectangle, the 200×200 Small Square, and the 250×250 Square.

Advertisers can chose a cost-per-thousand model for displaying ads, or a cost-per-click ad.

For advertisers, this change provides additional options and inventory for creating click-to-play video ads. Publishers may benefit from the increased competition among text, image, and video ads in these three formats; if a click-to-play video ad appears in one of your ad units, this means that it has won the auction against other ads and will generate the maximum earnings for you.
