have to be careful about reading the rankings on those tags though. i noticed a little flaw. tubebuddy is a plugin on your browser and its looking up rankings on youtube while you are logged into your youtube account. so the rankings might be a little flawed because youtube changes sort based on account activity. and the sort you look at may be different from the sort others look at from their accounts or devices.
sometimes tubebuddy will say im ranking in a really popular keyword that seems a little unbelievable because theres too much competition for that keyword. when i do search through my youtube account ill see my video ranked like tubebuddy said. but if i were to use another browser that is not logged into any account, then my video is not there. and so the sort results through your account is not going to be accurate since it is customized only for your account and not everyone else.
so its just a little thing to take note of when looking at the tag rankings. it can be affected by your account and you may need to double check from a clean browser to confirm.
