If you look carefully in your next Google search, you might just see a video ad included in the sponsored listings along side your organic results. It’s not obvious at first. You have to look for a version of the PlusBox, used for things like local search results and video in the organic listings, in the ads column.
I did a search today for [smart phone] (since [smartphone] didn’t return a video), and found an ad with an invitation to “Watch Commercial” under it:
When you click on the plus sign, the listing expands to display a video right there in the results. You also may need your grandmother’s magnifying glass as the video ads are tiny! They’re just 160×140 pixels, including the player navigation.
So far, it looks like only searches for “tech” terms like laptop or cell phone will trigger a video ad. Searches for cat food, personal finance, and luggage did not return any video ad results.
