Francois-Pierre Marcil: I think at this point, it can be somewhat of a bad decision even for the minimal boost. There is a value in having a brand when it comes to link building and promotional activities. It is more challenging to infuse values (what a brand can communicate) into a commercial name (possible).
Richard Hearne: Secondary effects can come to play here - if you brand yourself as the keyword, those branded anchor links you get can make a difference.
Does naming your domain a keyword you want to rank for that`s also a product you will sell help you rank better by Google?
