Liking YTtalk
I've heard a lot about the importance of a good and packed description, and how tags can also be attributed to it and that it's almost as important for them to be added into the description, but never practised it that much myself. However, I used to, occasionally, add such a thing about a year or so ago and to be perfectly honest, I think it worked.. I just got kind of lazy and viewed making a good description pointless since I, myself, never check other people's description that often, so why would everyone else? But these points that you brought up, which can I just say, were some really good tips! Are definitelly something that I'm going to be testing out, and I'll most likely be keeping track of that this week as well. This week is pretty much going to be my test on YouTube tags lol, I'll be sure to post whatever things more I discover whilst doing this, on this thread!
Well, you need to get used to writing extended descriptions, because believe it or not, a long decent description can still be meta food for the YouTube SEO. Even CC can also help even more to the keywords in a video.
