Don't forget to add it to your business cards, along with your email address. This is the practice of posting promotional or sales oriented messages in non-related newsgroups. The term comes from that old Monty Python skit where there was Spam everywhere. You're supposed to build your reputation, not destroy it. Sending people to linked pages that don't exist anymore.
Web pages are a dynamic environment.
If you've provided links to pages outside of your control, be sure to check them every few days to make sure they're still up and running. Focusing on features rather than benefits. Customers buy benefits , not features.
