I'm in on the Tik Tok hype. I'm just not too sure what "good" looks like right now for digital advertising for dealerships. I've seen some really great steps forward from Tik Tok for digital retail like allowing you to link in bios, as well as the ability to direct a click from their videos to a landing page. Will be interesting to see what the next step forward for them is.
Also RE: Vine, they fell away because of a lack of funding. Tik Tok fortunately (unfortunately?) is owned by a Chinese company called ByteDance with copious amounts of cash. They should be around for a while, and have a shown a willingness to make changes and adapt. We're trying new things with Tik Tok video and would love to share plans offline with anyone interested.
