Best practice for Youtube Tags?

I'm just wondering what the best methods are for Youtube Tags and getting suggested video views.. I'm wondering if I'm maybe being too specific with my tags. I've been using some pretty specific keywords for my TAGS on Youtube, and lately I was checking out some other similar videos from competitors and noticed they seem to be using tags which are very very broad or have almost nothing to do with the video.

So.. is it maybe a bad idea for me? Using too specific of keywords that is? I just shove a bunch of phrases in there that are super related.

I use long tail keywords who are having searching volumes in tags and my video is getting good views for them
