Hi guys! I have a youtube video, in which I discovered I have a really nice keyword giving me a lot of views. This keyword wasn't even included in the title, nor the description nor even in the tags, but it was included in the video content (the video is about this thing). I optimized the video with better description and tags, trying to focus a bit more on this keyword Should I change the title too? The title its 4 words length, as I think, the more words you put the more unattractive would be, I'm not sure about changing the title. Would a title change give me a worse positionating for the video?
