I had a digital sign-making business with small income (basically you design a sign on the website and I carve it out of wood with a CNC machine) the most traffic I got were from giving signs away as prizes on crafting blogs. It seems obvious in hindsight, but you have to be careful when cold emailing with "free" and "prize" in the body, I think more than half of my emails were filtered out as spam. * I had also tried adwords. It did give me a bunch of clickthroughs, but was not cost effective in the end.
