Group 4: Limitations and Challenges - Despite its advantages, PayPal's advertising business faces limitations due to the lack of a high-frequency entry point or a strong content ecosystem, which are critical for driving significant ad revenue [16][20]. - The advertising products currently offered do not create new traffic sources but rather optimize existing ones, making it challenging for PayPal to establish itself as a major player in the advertising market [17][20].
