3. Baidu Brand Zone

Specifications are highly tailored and negotiated directly with Baidu, but generally demand high-quality, professional-grade assets.

General Creative Best Practices for Baidu in 2026

1. Mobile-First Design: Over 90% of Baidu traffic is mobile. All creatives must be optimized for smaller screens, faster loading, and touch interactions.
2. Localization is Key: Beyond translation, adapt your visuals and messaging to resonate with Chinese cultural nuances and consumer preferences. Avoid imagery or concepts that could be misinterpreted or deemed inappropriate.
3. High-Quality Visuals: Blurry or pixelated images are immediate turn-offs. Invest in professional photography and video production.
4. Clear Call-to-Action (CTA): Every ad should have a clear, concise CTA that guides the user to the next step.
5. A/B Testing: Continuously test different headlines, descriptions, images, and videos to identify what performs best with your target audience. Baidu's ad platform provides robust A/B testing tools.
6. Compliance & Review: Baidu has strict advertising regulations. Ensure your creatives avoid prohibited content (e.g., exaggerated claims, sensitive political topics, certain medical claims). Pre-emptively check Baidu's advertising policies to avoid delays or rejections.
7. Leverage AI Tools: Explore Baidu's own AI-powered creative tools or third-party solutions that can help generate ad copy variations or optimize image sizes automatically.
8. Interactive Elements: Where possible, integrate interactive elements like short quizzes, polls, or swipeable galleries, especially for feed ads, to boost engagement.
