PayPal Ads publishes Adorama and Best Buy campaign results at Cannes

PayPal Ads released advertiser results from Adorama and Best Buy, arguing that its cross-merchant Transaction Graph and Storefront Ads drive measurable sales growth. Adorama reported a 7.3x incremental return on ad spend and a 14.9% incremental transaction lift, and Best Buy reported a 6.25x return on ad spend. These are company-reported campaign figures, and Etsy disclosed no numbers.

• Adorama: 7.3x incremental ROAS, 14.9% incremental transaction lift (April 2026 campaign)
• Best Buy: 6.25x ROAS (February 6 to March 31, 2026 campaign)
• Transaction Graph cited at more than 25 billion transactions and 400 million-plus PayPal and Venmo accounts
• Etsy testing an integration with PayPal's Conversion API; no figures disclosed
