Welcome to the Q&A Forum

Hi Greg, from my own experience I would follow Robert's advice and build the micro-sites.  But only 301 redirect them once they are ranking well independently.  To get them to rank you will need to publish some relevant content (not spam) and build up some quality backlinks to each. I would advise against simply forwarding them, type in traffic will probably be minimal.

Thank you all for the swift and informative responses. This put this issue to rest, going to stick with the full URL, http://www.smallbusinessdoer.com. I already have the smallbizdoer.com and smallbizdoer.ca URL's 301 forwarding to http://www.smallbusinessdoer.com.

Great, that's good to know!

Hi Greg, I confirm, they don't pass link juice, they are blocked by robots.txt. http://feedproxy.google.com/robots.txt Best regards, Guillaume Voyer.

Hi Steven, As this is a year-old thread, it's not going to get too much attention. Can you please send an email to our help team at help@seomoz.org and let them know about this? Thanks!

Right, the most important keywords are the first one's on the left. If you feel it best to add a title, do it, but it will be slightly better Search Eninge Ranking wise to omit the title.
