The Problem

Browser extensions are hijacking affiliate commissions

Malicious can replace affiliate tags at checkout. Your legitimate affiliates lose commissions, and you pay the wrong people.

Tag Hijacking

Extensions swap legitimate affiliate tags for their own at the last moment, stealing commissions silently.

Unhappy Affiliates

Your best affiliates lose commissions they earned, damaging relationships and your affiliate program reputation.

Wrong Attribution

You pay commissions to hijackers instead of the affiliates who actually drove the traffic and conversions.
