The Product
An educational book for children, sold entirely online in Poland. The target audience: parents looking for learning materials for their kids. A straightforward e-commerce setup — ads drive traffic, traffic buys the book.
The Starting Point
The campaigns were already profitable. ROAS sat at 3–4x, which for most businesses is a solid result. But the data told a different story — click-through rates were decent, the audience was right, the product page converted well. Something in the creative was leaving money on the table.
What Changed
One word.
Through A/B testing, we discovered that adding “free delivery” to the ad creative was the lever. Not a new video. Not a redesigned landing page. Not a different audience. Just two words in the copy that removed the last mental friction before purchase.
Parents were already interested. They were already clicking. But “free delivery” turned hesitation into action. It addressed the unspoken objection — “how much will shipping cost on top?” — before it could even form.
The Results
| Metric | Before | After |
|---|---|---|
| ROAS | 300–400% | 1,000% |
| Sales volume | Baseline | 5x |
The same budget. The same product. The same audience. ROAS jumped from 3–4x to 10x, and sales volume increased fivefold.
The Takeaway
You don’t always need a bigger budget or a completely new strategy. Sometimes the gap between “good” and “exceptional” is one word that removes the right friction at the right moment. But you’ll never find it without systematic creative testing — because no one would have guessed that “free delivery” would more than double the return.
