With a detection count of 2054, it is a proven commodity for driving return traffic. It is particularly effective for retailers like those found in its top sites, such as 1011now.com and 13abc.com, where re-engaging past visitors via external display networks is a critical KPI.
When to choose Optimizely
Optimizely should be the preferred selection for teams requiring a robust digital experience platform that extends beyond simple ad delivery. It is ideal for businesses that need to create and test personalized digital content across multiple channels rather than just serving display ads. If your technical roadmap includes experimentation, content management, and integrated commerce tools, Optimizely provides the necessary suite for driving engagement. Its presence on sophisticated sites like adyen.com and abnamro.nl underscores its utility for enterprises that prioritize deep digital experience optimization and growth-focused experimentation over pure retargeting.
