Baidu AI Source Tier System: How Your Site Is Classified

Baidu's AI-driven search now classifies websites into 5 tiers based on authority, originality, and trustworthiness. Your tier directly affects visibility in Baidu's AI answers.

The 5-tier system

Tier 1: Authoritative official sources (government, academic). Tier 2: High-quality media and institutions. Tier 3: Professional content sites. Tier 4: General content. Tier 5: Low-quality or suspicious.

How tiers affect AI visibility

Baidu's AI answers preferentially cite Tier 1-2 sources. Tier 4-5 sites are rarely, if ever, referenced. Moving up one tier can increase citation rates by 300%.

How to move up

Improve content originality, add author credentials, build external citations from authoritative sources, maintain content freshness, and ensure EEAT signals are strong.

GEOScope's role

While GEOScope focuses on global AI engines, understanding Baidu's tier system helps Chinese-facing sites optimize for domestic AI visibility alongside international GEO.

Key Takeaway

Baidu's tier system is the Chinese AI search equivalent of Domain Authority. Know your tier, then optimize to climb.
