90% Match Rate Achievement: How E-commerce Companies Maximize Meta Advertising ROI with Enhanced Data Quality

Unlock Meta's Full Advertising Potential

Transform your e-commerce Meta advertising performance with high-quality server-side data transmission that maximizes match rates and delivers superior campaign optimization.

The Challenge: Low Match Rates Limiting Meta Performance

TrendyFashion, a rapidly growing online retailer with $12M annual revenue, was struggling with their Meta advertising performance despite significant ad spend. Their main challenge was devastatingly low match rates - only 42% of their conversion events were being matched back to Meta users.

Understanding Event Match Quality

Event match quality is a critical metric available for website events sent through the Conversions API with the action source parameter set to "Website". According to Meta's official documentation, this score indicates how effective the customer information parameters sent with server events are at matching events to Meta accounts.

Meta calculates event match quality scores from 0 to 10 based on:

• The quality of customer information you're sending for specific server events
• The percentage of event instances successfully matched to Meta accounts
• Data from the last 48 hours to ensure up-to-date scoring

The iOS 14.5+ Reality

Post-iOS 14.5 tracking limitations created multiple data quality issues:

• Browser-based pixel tracking was increasingly unreliable due to Safari ITP and iOS restrictions
• Customer data inconsistencies between their e-commerce platform and Meta
• Missing conversion events from mobile app purchases and email-driven sales
• Poor data enrichment with only basic customer information being transmitted
• Delayed event transmission causing attribution windows to expire

The Business Impact

Low match rates were directly affecting their bottom line:

• $180,000 monthly Meta ad spend with diminishing returns
• Campaign optimization struggles due to insufficient conversion data
• Increased cost per acquisition by 73% compared to pre-iOS 14.5 performance
• Limited audience insights for lookalike and custom audience creation
• Competitor advantage to brands with better data infrastructure

• Enhanced conversion attribution back to your advertising campaigns
