I’m Not Interested
If you’re involved in direct selling, don’t assume all of your Facebook friends are interested in your product. Create a Facebook page for your enterprise, and invite your friends to like it. Use the page to reach your audience, not your personal profile. This allows you to market heavily to those that are interested, while not putting off the rest of your friends. Requiring a potential customer to opt-in is always better than requiring everyone that isn’t interested to opt-out. Do you like spam? Neither do I.
