Snapchat releases Snap Publisher: self-serve ad creation tool converts horizontal videos, websites into vertical video ads

One of the knocks against advertising on Snapchat is that it’s hard to make ads for Snapchat. The mobile app’s insistence on vertical video compels advertisers to create campaigns from scratch rather than reusing ads that ran elsewhere. Now Snapchat is addressing that obstacle. On Monday, Snapchat officially rolled out a browser-based ad creation tool, Snap Publisher, that anyone with access to its self-serve ad-buying tool, Snap Ad Manager, can use to create Snapchat’s vertical video Snap Ads, whether or not they have any vertical videos to use.
