I'm glad I found this thread! I just found out about it today, and am curious to know if it actually helps grow your channel. I know that I could use some help in the SEO/tags department. lol in the tags, I just throw in words that are related to my video with different variations... not sure if I'm doing it right or not. But being a new youtuber, I need all the help I can get to get ranked in the searches. Lol so if it helps with that, I think it would be worth a try. But I'm not sure if the free version will actually help or if I'd actually need to pay to get what I want from it. ...in my experience, the free version of ANYTHING requires you to pay to get the full effects of what the service claims to do.
