...on a popular, left-leaning blog a few weeks back. For $80, my ad - which consisted of a rotating depiction of a few Wavelength shirts, and some accompanying text - ran for 1 week.
According to the ad provider, Blogads.com, about 98,000 people viewed the page the ad was on over the course of the week, and of these, 174 clicked through to the Wavelength site. This represents a click-through rate of 0.177%, which sounds tiny but is actually respectable in the world of online advertising (a click-through rate of a full 1% would be considered superb).
Did the ad boost sales? Well, with another Wavelength ad running concurrently on AfterDowningStreet.org, it's hard to precisely quantify the number of shirts this new ad helped move. But my rough estimate is that the $80 I spent on the ad ended up pushing about 5 extra shirts out the door. Not quite profitable, but an interesting experiment nonetheless.
