I think I have just stumbled on a very interesting keyword. Even before the site was launched, I have already appeared on Page 1 of Google (probably happened by just listing the site on Facebook). It's just so quick and exhilirating but now I need help optimising the site for this keyword and determining the type of content I need. This keyword does not have many articles as it's quite specific.

Note: Violinrolling is NOT the keyword, just an example.

Questions:

1. I bought the .net domain of the keyword as the .com is taken. Should I also buy the .net of the keyword(s) as the .com is also taken? The keyword with "s" doesn't have as many searches as the original keyword. Eg: I bought violinrolling.net, should I buy violinrollings.net as well?

2. Let's say the keyword is violinrolling. If I were to write an article for this keyword, do I have to include "violin rolling" in its generic form no matter whether the article makes sense or not, or can I do "violin is rolling" or "the violin will be rolling" or "violin on rolling"?

3. Affiliate Offers: I have found some affiliate offers for violin classes but there are others for guitar classes. Or even some for general music stuff eg classes for music theory, should I promote these as well? How should I do this, eg thru banners, articles?

4. Ideas for Topics: "How to play violin", "How to roll chords on violin", "Rolling on the Violin". Is this ok?

If there are other ideas, please share them in this thread.
