For the longest time, we were completely obsessed with click-through rate. If an ad had a high CTR, we kept it. Low CTR? Immediate kill. It felt logical - more clicks must mean more sales, right?
But our results were all over the place. We'd see beautiful CTRs on ads that sold nothing, while some truly ugly, low-engagement ads quietly carried the entire account. It didn't add up.
So a few weeks ago we shifted our approach entirely. Instead of optimising for click behaviour, we started looking at marketing efficiency ratio (MER) and blended performance across the whole funnel. We also invested in proper tracking that goes beyond what the platforms report. That's when things got uncomfortable.
Turns out some of our best-performing CTR ads were actually losing money when you saw the real revenue. And those ugly ads that barely got a second glance? They were the financial backbone.
Now we ignore CTR completely unless it's truly terrible. It's like judging a restaurant by how many people walk past the window rather than how many come in and spend money. The walkers look good on paper, but the spenders pay the bills.
We were optimising for a vanity metric without realising it. The shift to actual revenue impact has changed everything - budgets, creative strategy, even how we brief designers. I'm curious if others have made this switch, or if CTR still holds a sacred spot in your optimisation playbook.
