At the risk of sounding like a broken record... if someone is providing SEO services for you, you should familiarize yourselves with, at least, the basic concepts and receive reporting of what they're actually doing. This will help you to not throw money down a magical SEO snake oil hole. Ask for samples of their reporting, as well as client referrals.
