A tracking pixel is a small piece of code placed on your website that collects data about visitor behaviour. Essential for conversion tracking, retargeting, and campaign optimisation.

- Track conversions back to ad clicks

- Enable lookalike audience creation
- Provide data for algorithm optimisation

Server-Side Tracking
With browser privacy changes (iOS 14, cookie restrictions), server-side tracking is increasingly important. Meta Conversions API and Google server-side tagging send data directly from your server.

- Use Google Tag Manager for easier management
- Implement both browser and server-side tracking
- Test that events fire correctly
- Ensure privacy compliance (cookie consent)
