Why didn't you wait to submit this until you actually had something to show, then? Could you even give a couple of tips other than "be good at targeting"?
Sorry, I'm not trying to be snarky, maybe I haven't had enough coffee today or something.
I don't normally have a set period of time in mind, I just do it until it has enough views/clicks for the difference to look statistically significant.
I probably should be doing actual statistical significance testing, but I'm lazy, so just do it intuitively.
And about 200% better than when I used the profile pic image that I use on the Facebook page (from what I've heard on the grapevine company logos while great for branding tend to have very low CTRs):
(these datapoints aren't in the image I show on my blog; I tested them after I wrote most of that article and took that snapshot)
I should also point out that in CoderStack's ad campaigns cartoon images performed worse of all the images I tested, for CoderStack the best performing images were photographs of people. So there's no "one-size-fits-all" solution.
Cool, I guess one aspect of your best one here would be that it's more interesting the the equally easy to read logo. The other 2 cartoon images are probably hard to get at a glance at the small size you see the ad images at.
It's interesting because the limited campaign I have dealt with before used a logo and tagline type display, probably not the best.
None of them are readable at that size, it's about the general look. I don't know if these links are permalinks or not but here's the images at Facebook Ad size:
