Look for more online video ad spending in 2010. In a new BrightRoll survey of execs and media buyers at ad agencies, 94% said they plan to spend more this year.

Over half agreed that online video advertising was more effective than other forms of advertising, and full 83% thought they get more value for their dollar.

Why? Online video ads cost much less while offering better targeting. Plus there’s plenty of quality inventory. Their only concern? Ensuring the placement of their ads is consistent with their brand.

Cost per video view: 45%
Cost per engagement: 34%
Cost per impression: 16%
