A furniture maker slaves over a lathe during the day but she moonlights as an SEO. When a plumber in Cedar Rapids finishes mending clogged pipes, he goes home to add negative keywords and optimize bids. When I freelance, I am biz. dev. guy, creative talent, accountant, or debt collector depending on the day of the week.
My point is this: the tired adage about small business owners and hats might be played out, but it’s completely true.
