Here’s what I used to think long, long ago, before I dipped my toes into the real-world:
When I see something stupid, that means that someone, somewhere, made a stupid decision.
That feels like common sense, almost even tautological. If it is stupid, then someone did something stupid.
Oh, if only I lived in a world that simple!
To explain an alternative world view, let’s take an example very relevant to display ads:
When you see mistakes of typos in an ad.
Like this ad, that I saw while online on my phone the other day:
What stood out to me about that ad is the obvious typo: find your quirks, talents and your “hidden weak.” Your hidden weak? What language is that? Not English!
Now, the younger version of me would have laughed. “Ha!” I would have thought, “The idiots [hired to write this ad copy] in [insert name of country here where English isn’t the common language] can’t even write simple grammatical sentence!”
(I was an a—-, wasn’t I?)
The definitely-older and possibly-wiser version of myself sees typos and wonders: is it on purpose? Perhaps, perhaps, perhaps as the classic song goes.
Take spam, for example. Here’s a well-known fact: spammers put typos into their emails on purpose. What? Why? Because smarter people are statistically more likely to use the typo as a marker of sketchiness and thus delete the email. And thus the stupider people–let’s say, the less sophisticated people–are the ones more likely to respond. Now that is targeting: the spammers want only the most gullible to respond, and typos help auto-select the less-gullible out of the target market.
The same definitely goes for display ads. A few years ago, I ran an ad campaign for a travel startup and I put a typo into the ad, accidentally. I wish I could say it was a test on purpose, but alas, it wasn’t. But when I realized it, I ended up not fixing it but creating a new ad to A/B test against the original. And guess what? The typo version got more sales. By a lot! Since then, I’ve recreated that conclusion in some contexts, but not all. (I would be hesitant to use a bank that had typos… maybe a typo causes a zero to disappear at the end of my account balance!)
The conclusions here are two-fold. First, don’t take ads at their face value. Secondly, test, test, test. Maybe “mistakes” can help improve your conversion rate.
