After years of listening to my customers complain about not only the expense, but the poor results using "SEO specialists" to market their sites, I've come to the conclusion
that small businesses need to take their own marketing in hand. Even if it means hiring an in-house person to manage and track SEO efforts.

I have recenly found a program (WebCEO) that allows management of submissions, keywords, comepetition and even ppc advertising, and provides statistical reports that most people with a minimum of internet experience can understand.

See: SEO Software by Web CEO :: Search Engine Optimization Software / Complete SEO Toolkit :: Website Optimization, Promotion and Submission SEO Software

It's a free download, most features are free to use, with some specific areas that are subscription based. (At the prices SEO professionals charge - even these subscriptions are a bargain!) They even offer training for those who want to use WebCEO management as a service to offer their clients.

Good Luck!
