General rule of thumb:
A well-tagged video has:
- Closely related Tags
- General tags (but not too many) as well as detailed ones
- Not too similar tags (That's something pretty easy to find spam with)
- Use Tags that you (or a sane person) would search as an exact keyword when looking for your video
Use closely related Tags to get people interested in both topics.
Use General Tags to be recommended to people otherwise searching for the video
Use different tags (not
minecraft lets play, minecraft lets play survival, minecraft lets play map)
I'm against saying "Don't use overpopulated tags". Overpopulated tags (e.g.
minecraft) are mostly the tags people search for/watch the most. It should be more like "Don't
only use overpopulated tags". Think like this:
YouTube wants to show user X a video. User X is interested in Physics and geography. What will YouTube show?
- Your video tagged with travelling the world
- Your video tagged with geography
- Your video tagged with both
Exactly, both. Even though
geography is more of a popular tag and you will not rank with it, it does generalize your video.
Also I am against rapidtags with a burning passion as the last time I checked it returned tags I wouldn't rank on even if I was PewDiePie as well as blatant spam I'd get shut down by YouTube for (even if I was PewDiePie). Write your own tags, sit down for an hour and think of good ones and you will rank higher. I made a garbage video that has half my views just because it ranked on a popular topic.
