So in my "thoughts on a promotion idea" post SGL suggested I consider starting a "campaign" on Project Wonderful. Campaigns are ad blitzes where you tell PW how much money you're willing to spend for how long, give it some parameters, and then it goes and automatically has you bid on any ads in the PW network that falls under your guidelines.
I had about $36 in my PW account, so I decided to try a campaign for 5 days. It started Sunday, ended today. Here's how it worked out for me.
I put in $30.00 and set the duration for five days. This means that if the advertising went beyond $30 before the five days ended, it would end prematurely. I also put a daily cap on total bids of $6.00. This meant that there would be no danger of the campaign ending prematurely.
At the end of the campaign:
My ad had 186,800 hits. 90,174 were "unique" (basically unique hits track first-time viewers. If someone runs into the ad multiple times, they are only counted once for unique hits).
Of those 186,800 hits, the ad was click 97 times (clicking the ad takes you to curveballchronicles.com). 93 of those clicks were "unique" (I assume this means there were 1-4 visitors who clicked on the ad more than once.)
The click through ratio for my ad was 0.05%. If you count only unique hits, the click through ratio is adjusted to 0.1%, which is better. Though not great.
The total cost of the ad run was $23.26. Which is only 78% of what I budgeted. Not bad there. Essentially this means I wound up paying 24 cents a click. That's a bit rich for my blood. However, I was pretty broad about where I targeted my ads, and if I were more focused on specific audiences I might do better.
