While on this topic:
How does everyone feel about links from indirectly related sites?
Example: Our business sells widgets, and is woman-owned, and we are participating in some green technology programs to try and reduce our environmental impact. But instead of concentrating on getting links from widget information pages, how about getting links from sites for woman owned / minority owned businesses? Or from green technology sites?
We have a friend who sells certified fair trade widgets, and he says that "most of his orders" are referred from the fair trade certification web site. So there is the referral boost as well as the link juice boost to consider.
