I registered a domain name about 18 days ago. I wrote articles targetting the keyword, submitted to Ezine, put 4 keyword rich article on the site itself, and completed a 8 spoke link wheel. My domain has the keyword in it (but with dashes, as the domain without dashes was unavailable). The keyword has 281,000 results on google..fairly low competition. I am aware that results aren't seen over night, but considering this is a very low competition keyword, shouldn't I see myself ranking for the keyword by now?
