To add my thought to already gven point. Tubebuddy is not sub to sub so people miss it when they think they are here to get more sub. Tubebuddy tools are very good for new and Younge Youtubers as your brand is still not known. I will give you my favourite tool
1. Videos --- I spent so many times watching all the videos when I started out. Andrew have made so many fantastic videos that u need to take our time to watch. Why make the same mistakes when people are willing to teach you what eerrors they did.
2. Tags--- I normally spend hours on tags, title and description until I understood the explorer tool. I know people think tag doesnt help but it has given me views this few weeks I have learnt how it works.
3. Channel page Analystic- I love the Chnannel analysis I see once I open my page. It give me best practice report so I know what I have done well.
4. This community--- I have worked as a marketer and consultant. This forumn is an avenue for me to get feedback from other creators who understands the passion I have. I love creating video, editing and having the conversations with people based on my content. The feedback here are very supportive and done in a friendly manner.
There are so much to say, but you need to learn it by yourself. I am on Pro but I have checked out what 'STAR' and ' Legend' package does. Wow they are tools that will help your SEO.
Finally, friendships are made and communities are built.
