Account and Pixel Ownership Rules

The most critical question you can ask an agency is: 'Will we retain 100% ownership of our Meta Business Manager, ad accounts, pixel data, and custom audiences?'

Many agencies build campaigns inside their own proprietary accounts. If the relationship ends, you lose all historical data, pixel optimization training, and the capacity to run remarketing campaigns. This is a severe business risk.

Attribution and Conversions API Frameworks

Ask: 'How do you handle cookie timeouts, iOS tracking limitations, and server-side tracking integrations?'

Key Finding: Any agency relying purely on the browser-side Meta pixel in 2026 is obsolete. A professional partner must have a documented protocol for deploying Meta Conversions API (CAPI) and configuring first-party subdomain tracking.

Creative Testing and Refreshes

Ask: 'What is your creative testing workflow, and how often do you refresh our visual assets to prevent ad fatigue?'

Modern Facebook advertising is primarily driven by creative diversity. Your agency must have an active pipeline for testing copy hooks, angles, and video layouts systematically rather than just adjusting audience targets.
