You described a good backgound job to do before asking a question. I would also add that a an identification question must have an interest for the next person that could be in the same situation.

In a poor post like
> * https://musicfans.stackexchange.com/questions/4130/the-name-of-this-song.

I can't see how another user asking himself the same question will google and end in this question.

In good posts like
> * https://musicfans.stackexchange.com/questions/2537/what-metal-song-is-used-in-this-trailer-for-an-upcoming-animated-movie
> * https://musicfans.stackexchange.com/questions/4354/video-clip-of-a-song-in-a-beach-big-guy-with-pink-glasses
> * https://musicfans.stackexchange.com/questions/3112/instrumental-used-in-old-popeye-cartoon-unknown-music-from-30s-or-earlier

There a enough details and keywords to be found with google, so another user can find it.

**Try to add keywords that the next person in your situation would have in mind.** Is it a song from a commercial, from a movie, the opening theme of a tv show...?
