I implemented a full Facebook Ads tracking setup, including domain verification, Meta Pixel integration, and the Facebook Conversion API via Facebook Business Manager. Domain verification ensures ownership control and enables prioritized event tracking, essential for iOS 14+ compliance. The Meta Pixel tracks user actions like views, carts, and purchases, while the Conversion API sends events directly from the server—ensuring accurate data even when browser tracking is limited. This setup significantly improved ad targeting, attribution, and campaign performance.
