Found a nice little niche today, keyword is: "keyword1 keyword2 keyword3", and it has about 8000 searches a month in google keyword tool. Allintitle only shows 63 other sites (These are norwegian keywords btw). average cpc is 5$. Now, domain http://www.keyword1-keyword2-keyword3.mytld if available, and so is the same without hyphens. So first of all, is this a decent niche to go after, and second, what domain should I buy? with or without hyphens?
