At first, I assumed they would be too simple compared to more visual formats, but the results proved otherwise. Because notifications appear directly on users' devices, they tend to attract attention without feeling overly intrusive. I noticed higher engagement rates, especially when campaigns used clear messaging and strong targeting. Tracking click-through rates, conversions, and return visits revealed that even small adjustments in timing and audience segments could improve performance significantly. The format also worked well across different niches and budgets, making it a flexible option for testing and scaling campaigns.
