Hello! I've a question about tags on YouTube... I normally use as many tags as possible to gather more views / traffic. However, I've noticed that after some time YouTube automatically updates the tags of my videos, either by replacing the current ones with other ones or by removing some of the tags I used. Now, my question is, if we use tags for example: 1. how to lose weight 2. how to lose weight fast 3. how to lose weight fast in 2 weeks Does the tags 1 and 2 matter if we use the tag 3 only? Since the tag 3 contains both 1 and 2 keywords, are they useless or should I use all of them? Thanks in advance.
