Many brands don't realize they are paying commissions on sales they would have gotten anyway (coupon poaching) or that their commission tiers are eating their margin.
Industry benchmarks show that without active management, up to 30% of affiliate commissions are paid out to coupon-scraping sites that add zero incremental value.
If you are paying out $10,000 a month in commissions, you could be wasting $3,000/month on sales you would have made anyway.
