Yes, starting with interest-based targeting is a smart move when your pixel is new and has no data. Meta’s algorithm needs initial user behavior signals (clicks, leads, purchases) to begin optimizing effectively.
Here's Why Interest Targeting Works Early:
Pixel is cold → it has no past conversions to guide broad or lookalike targeting.
Interest targeting gives Meta some structure to find likely buyers and collect early data.
Once you’ve gathered enough events (20–50+ conversions), you can gradually move to broader targeting or lookalike audiences.
Tip:
Start with 2–3 strong interest groups related to your course niche, monitor which converts best, and feed those signals into your pixel for better optimization.
