PDG specializes in database applications for the Internet and Windows, not in marketing; although we can do rudimentary actions, such as preparing the site for the search engines. We subscribe to Web Commerce Today and Web Marketing Today, e-mailed newsletters put out by Dr. Ralph Wilson. The marketing one is free, and useful - to boot. Over the past few years I have been reading Wilson's newsletters. His level-headed advice has been very useful and his site has enormous resources. Check it out.
Dr. Wilson - he's cool.
