What is the most effective A/B testing strategy for video titles on Bilibili, considering the character limits and user behavior?

The most effective A/B testing strategy for video titles on Bilibili, given the character limits and user behavior, involves testing variations of the primary keyword and emotional hooks within the first 12-15 characters. Bilibili's character limits for video titles mean that the most important information needs to be conveyed quickly and concisely. Users often scan titles rapidly, focusing on the initial words to determine relevance. Therefore, A/B testing should focus on different variations of the core keyword, emotional triggers (e.g., humor, surprise, excitement), or benefit statements (e.g., 'learn how to...'). For example, if the video is about cooking dumplings, test variations like '饺子速成: [Brand Name]' versus '超简单饺子: [Brand Name]' ('Quick Dumplings: [Brand Name]' vs. 'Super Easy Dumplings: [Brand Name]'). Track the click-through rate (CTR) of each title to determine which resonates most effectively with the target audience. This approach maximizes impact within the limited character count and aligns with user scanning behavior on the platform.
