The 10 Most Watched Ads on YouTube in September

Headshot of Tim Nudd

Marketing giants Apple and Amazon finished No. 1 and No. 2 on Adweek and Google's YouTube Ads Leaderboard for September, ranking the most-viewed spots on the video platform, as they launched campaigns for the iPhone 7 and Echo, respectively.

Meanwhile, Clearasil and AT&T each made our monthly list for the first time, thanks to the Smosh video "Every High School Ever" spot and BBDO's "The Unseen" film. Supercell placed three Clash Royale gaming spots on the list, while Lyft showed up as well with another "undercover" spot, this time with Demi Lovato.

In addition to the No. 1 video of the month, Apple had the No. 5 spot as well. Interestingly, both were videos from the iPhone launch event, not the TV spots that rolled out a little later.

See all 10 spots below.

Note: To be eligible for Adweek and Google's YouTube Ads Leaderboard, videos must be marked as ads on YouTube (i.e., they get some paid views) but must also earn significant organic views. The algorithm factors in paid views, organic views and audience retention (how much of a video people watched).
