- Tracking by Collections – using the same pixel to target different audiences is not the best way to run ads. That’s where Tracking by Collections comes into play – you can still track up to 4 Main Pixels (allowing your main pixel to have up to 3 backup pixels), but now you can track up to 12 Collection Pixels. Collection Pixels allow you to break out your pixel ID’s by niche, allowing you to segment your pixel tracking data to build highly-focused, custom audiences and retargeting campaigns. Tracking by Collections keeps your Pixel Data clean and relevant. This is extremely Powerful.
