Do ad blockers hide real conversions from analytics?
Yes. Visitors with blockers often never fire your analytics or ad pixels at all, so their purchases go uncounted - and these users skew toward higher-value segments.
When a blocker prevents your analytics script or ad pixel from loading, that visitor's entire journey - including the purchase - can vanish from reported data. The result is understated traffic and conversions, with a bias: blocker usage is higher among technical and higher-income audiences, so the missing conversions are disproportionately valuable ones.
Server-side collection restores visibility because events are captured on your own infrastructure rather than by third-party scripts the blocker recognizes.
