Should I go for a broad domain name so it isn't limited to just one scenario, e.g. Dogtraining-fast.com (which has no searches but readers from several keywords would click on that link), rather then Dogtrainingforeskimos.com (where I know I can rank for that keyword; if it has, say, 500 exact views a month - But mostly people searching that keyword would click on it; reducing possible traffic from a wide range of keywords)?
And another question. Would you suggest sticking to, say, 10 keywords with 100-300 exact views a month, so it would be easier to rank?
I've confused myself writing this, so I hope you can make something out of it.
PS. The niche is an EXAMPLE.
