Voluum/tracker vs in-platform numbers — trust which?

Voluum/tracker vs in-platform numbers — trust which?
Platform pixel → fast, optimizes delivery, but inflates conversions (view-through, dedup chaos) and hides the post-click truth.
Tracker (Voluum, RedTrack, Binom) → real click-to-conversion path, sub-id breakdowns, the number you actually got paid on. Slower signal, more setup.
Field rule: optimize the algo on pixel, judge profit on the tracker. When they disagree by more than 15%, the tracker wins your kill decision.
Never pause a campaign on platform numbers alone. That's how you axe a winner.
