Maybe it's not only marketers, what about people who watch the video and think this is a scam? Maybe it's them, I don't think marketers can do that instead we watch and learn then do something similar or better. Some even steal your video and upload it on their channel haha... Now that's a marketers mindset.
I still use Youtube the old skool way, demonstrate a free working strategy in the video & a link to a squeeze page in the description and watermark (link on video). I should try this video review stuff...
