Reconciled three months of conversions between my tracker, the network dashboard and the ad platform.
Network said 4,112 conversions. Ad platform said 5,790. My tracker said 4,480.
None of them are lying. They are counting different events over different windows with different dedup rules. The ad platform counts a 7-day view-through; the network counts a 24-hour post-click. If you optimise to the ad platform's number you will scale something that is not making money.
Pick one source of truth, make it your tracker, and treat everything else as directional.
Paid traffic is just SEO with a faster feedback loop.
