I haven't followed this Allie O girl, but I just watch this video (the first 3 minutes of it). I have to say, it's pretty well done.
It's edited well. There's very little dead space. There's beautiful scenery. She opens herself up and exposes a vulnerability right away. People love that stuff, even if they won't admit it. She also doesn't reveal too much, smartly. She leaves you wondering what the big reveal is. That's enough mystery to keep viewers coming back.
All told, she's got 10s of thousand of subscribers and videos with up to 1/2 million view on them.
Looking at it objectively, she's not doing the influencer this too badly. After all, she's got a thread on a topical forum about he video and is racking up clicks as we speak.
I give her video an A-. She would have gotten an A+ if she intrigued me enough to watch past 3 minutes, which she didn't. But she got my click (thanks to you haters).
