The ad our client thought was a mistake

One of our clients asked us to fix an ad they thought looked like a mistake. It turned out to be the highest-performing ad in their entire account.

The ad in question.

A few weeks back, our Creative Director, Casey, spotted a trend taking over feeds: “ugly” ads. Plain, text-heavy, a little rough, the kind of thing that looks like a note typed on a phone, not something an agency made. They break every design rule, and they are the ads people actually stop to read. So we ran one in a prospecting campaign, straight against our polished, on-brand creative, and let the data decide.

Then the client spotted the ugly one out in the wild, flagged the uneven spacing and a stray comment, and asked us to tidy it up. Fair reaction, it didn’t look like a normal brand ad. But we pulled the numbers first. That “mistake” was carrying the whole campaign, and winning on cold traffic, the hardest audience there is, people who’ve never heard of the brand. The polished ads couldn’t get near it.

The lesson: your gut reaction to creative, and often your client’s too, rarely matches how it performs. The ad you’d frame on the wall and the ad that actually sells are usually two different ads. That’s why we test.

If everything in your account looks polished and on-brand right now, that’s exactly when I’d get curious. Your next top performer might be the ad you’d never let yourself post.
