The Ultimate China SEO Checklist 2026

China SEO is a multi‑layered discipline. This checklist breaks it down into eight phases—from the legal foundation to advanced GEO (Generative Engine Optimization). Each item includes a brief "why" to help you understand its importance. Use it as a project tracker, an audit tool, or a training document for new team members.

Phase 0: Legal & Compliance Foundation

Before a single line of code or piece of content, you must establish your right to operate in China's digital ecosystem.

• ICP License obtained – For commercial sites, a full ICP license. For non‑commercial, at minimum ICP Filing (beian). Allow 4‑6 months if foreign ownership is involved.
• PIPL data map completed – All personal information collected from Chinese users mapped, with legal basis documented.
• Privacy policy in Simplified Chinese – PIPL‑compliant, clearly accessible, and reviewed by local counsel.
• DPO appointed and reported (if applicable) – Required if processing >1 million individuals. Reported through CAC system.
• Cross‑border transfer pathway defined – Exemption, Standard Contract, Certification, or Security Assessment in place.
• Domain strategy set – .cn domain registered or .com ready for ICP; exact‑match domains secured.

Phase 1: Technical Infrastructure

Your website's hosting, speed, and crawlability determine whether Baidu can even find your content.

• Mainland China hosting or China CDN – For optimal speed, use Alibaba Cloud, Tencent Cloud, or a domestic CDN (requires ICP).
• Responsive web design – Baidu is mobile‑first. Same HTML on mobile optimization in China and desktop; avoid separate m‑sites.
• Page speed optimized – First Screen Load ≤1.2 seconds. Use WebP, lazy loading, minification, and a China CDN.
• Critical content in HTML – Baidu can render JS but prefers HTML. Core information must be accessible without JS.
• SSL certificate installed – Ensure compatibility with China's root CAs.
• Baidu Webmaster Tools verified – Site added and verified via file upload, meta tag, or CNAME.
• Sitemap submitted – XML sitemap ≤10MB or 50k URLs, uploaded and submitted in Webmaster Tools.
• URL push implemented – API push for new pages, or automatic push JS snippet installed.
• Baidu Tongji installed – Tracking code in , linked to Webmaster Tools for keyword data.
• Crawl diagnostics run – Tested key pages with Baiduspider; no 404s, 500s, or blocking.

Phase 2: Keyword Research & Intent Mapping

Understanding what your audience searches for—and why—is the foundation of all content.

• GEO entities identified – Related concepts, people, standards, and questions for AI search optimization.

Phase 3: Content Creation & Localization

Content must be created by Mainland China natives, optimized for both users and AI, and compliant with advertising law.

• Each title optimized – Keyword in first 10 chars, ≤30 chars total, emotional hook (curiosity, benefit, identity).

• Meta description written – ≤108 chars, includes keyword, value proposition, compliant.
• Meta keywords tag populated – 3‑5 core terms (Baidu still uses this).
• FAQ section with schema – Question‑based headings and structured data for AI extraction.
