I'm sorry I didn't see it until now. Since that Tool is installed on a Ning page, I don't get notifications when someone leaves a comment.
The keyword combo: ethical networking comes up for me 2 times - - but it should come up more, since this is one of your primary keyword combos.
I would suggest adding a tag cloud with ethical networking and your other keywords. Also, add tag links at the bottom of your page in your Footer - - see example here at bottom. As long as you don't leave too many duplicate tags, you're safe with Google. Otherwise, considered stuffing and can hurt your indexing.
Also, and be careful with this one too on the "stuffing" - - within reason, leave ethical networking in image tags as the alt text. This helps a lot on Google indexing.
I should have this on your comment, you may already know all this. I hope you don't mind my suggestions. ;-)
