Show HN: We Paid Facebook to Convert People Who Were Buying Anyway

2 points by bmahir 19 hours ago

Retargeting looked like a win, low CAC, solid conversion. So we kept spending.

But most of those users would’ve converted without the ad.

We were just paying Facebook to take credit for what was already happening.

Our reported ROI was a lie and we didn’t even know it.

We built kruxel.com to avoid this.

In just one prompt it shows true incremental impact by comparing retargeted users to similar users who weren’t shown the ad.

If there’s no real lift, we cut spend.

No fluff, no false credit, just decisions that move the bottom line.
