That’s according to the SEM Post.
Google sent The Drum the following statement: "We are constantly experimenting with ways to improve the search experience for our users, but have no plans to announce at this time."
Google also confirmed this is a short-term experiment with a small number of trailers - not ads - and it has no plans to roll it out further or make it a permanent feature.
SEM Post also said the queries that yielded autoplay videos were not specifically searching for videos. Results for searches for trailers, on the other hand, included the video in the main column. And, per the SEM Post, placement of the video varies from within the knowledge panel to beneath the Product Listing Ads.
The source of the video also varies – and doesn't include official sources, which SEM Post said could pose opportunities for brands.
Google autoplays the videos without sound when loading the search results page for desktop results only – and the videos only autoplay once. However, SEM Post also noted some browsers – and ad blockers – prevent auto play.
In related news, Pinterest told The Drum it is adding autoplay videos for advertisers in August.
