<b>Your best-performing native source is probably a bot farm</b>

<b>Everyone says</b> the source with the highest CTR and lowest CPC is your hidden gem. Scale it.

The data says that combination — cheap clicks, suspiciously high CTR, instant conversions — is the textbook signature of invalid traffic, not a unicom. Real humans hesitate. Real humans don't convert at 0.1s post-click with zero scroll depth.

Pull these three per source: time-to-conversion distribution, scroll depth before action, and click-timestamp clustering. When conversions pile up in the first 200ms and scroll depth is flat zero, you found a script, not a segment.

The sources you're proudest of are the ones you should blocklist first. Have you ever actually checked the one that looks too good?
