AEO vs SEO vs GEO: The New Search Optimization Stack for China

If you're running ads on Baidu, you've probably noticed something: the search results page looks different than it used to. AI-generated summaries sit above organic links. Featured snippets answer questions before users click anything. And increasingly, Baidu's ERNIE-powered search is pulling answers from sources that don't even rank on page one.

This is the new reality of search in China. And if you're only optimizing for traditional SEO, you're leaving traffic on the table.

Here's what SEO, AEO, and GEO actually mean — and how they work together on Baidu.

The Three Layers of Modern Search

Think of search optimization as a stack with three layers. Each one targets a different part of how buyers find information.

SEO: Search Engine Optimization

The classic. You optimize your website so search engines rank your pages high in the results.

What it targets: The traditional "ten blue links" on Baidu's search results page.

How it works: Technical health (site speed, mobile-friendliness), content depth (comprehensive, well-structured pages), backlinks from authoritative sites, and on-page relevance (keywords, meta tags, internal linking).

Best for: Buyers who still click through to websites — which is most B2B buyers researching suppliers, comparing prices, or evaluating options.

AEO: Answer Engine Optimization

This is about being the answer, not just a result. When Baidu shows an AI-generated summary or a featured snippet at the top of the page, AEO determines whether your content gets quoted in that answer.

What it targets: Baidu's AI summaries (文心一言 integration), featured snippets (精选摘要), "People Also Ask" boxes (相关搜索), and voice search results.

How it works: Structured content with clear headings, FAQ-style formatting, schema markup (FAQPage, HowTo), and passage-level clarity. You need to be already ranking in the top 10 for AEO to work — it's an optimization layer on top of SEO, not a replacement.

Best for: Informational queries where Baidu now answers directly in the SERP — "how to," "what is," "best [category]" queries.

GEO: Generative Engine Optimization

This is the newest layer. GEO targets the citations inside AI-generated responses — not just on Baidu, but on ChatGPT, Perplexity, Gemini, and China's own ERNIE Bot (文心一言), DeepSeek, and Tongyi Qianwen.

What it targets: When someone asks an AI "What's the best B2B advertising platform for China?" and the AI cites your brand or content in its answer.

How it works: Entity authority (your brand needs to be recognized as an authoritative source), distributed citation footprint (mentions on forums, industry directories, social platforms), and content that AI models can quote verbatim.

Best for: B2B buyers who use AI tools to shortlist vendors — which is increasingly common in enterprise purchasing.

How This Works on Baidu (vs Google)

The concepts are the same globally, but Baidu's implementation has some important differences:

The key difference: Baidu's AI search is more tightly integrated with its own ecosystem. When ERNIE generates an answer, it pulls heavily from Baidu's own properties — Baidu Zhidao, Baidu Baike, Baidu Tieba, and Zhihu. This means your GEO strategy for Baidu needs to include these platforms.

The Investment Split: Where to Focus

Based on our experience with overseas advertisers targeting China, here's how to weight your optimization efforts:

For B2B manufacturers (most BPP clients):

• SEO: 50% — Ranking for product and supplier keywords is still the primary lead driver
• AEO: 30% — B2B buyers increasingly use AI summaries to compare options before clicking
• GEO: 20% — Enterprise buyers are starting to use ERNIE and DeepSeek for vendor shortlisting

For SaaS and technology companies:

• SEO: 35%
• AEO: 25%
• GEO: 40% — Tech-savvy buyers are early AI adopters; being cited in AI responses is high-value

For local services (not applicable to most overseas advertisers):

• SEO: 70%
• AEO: 20%
• GEO: 10%

What This Means for Overseas Advertisers

Here's the BPP angle: all three layers require Chinese-language content and a presence on China's internet ecosystem. This is where most foreign companies hit a wall.

SEO requires:

• A Chinese-language website (not a translation — a localized site)
• Backlinks from Chinese websites (Baidu Zhidao, Zhihu, industry forums)
• Technical optimization for Baidu's crawler (different from Googlebot)

AEO requires:

• FAQ-style content in Chinese, structured for Baidu's snippet extraction
• Schema markup that Baidu recognizes (not all Google schemas work on Baidu)
• Being in the top 10 organic results (which requires Chinese SEO first)

GEO requires:

• Presence on Baidu's ecosystem (Baidu Baike, Baidu Zhidao, Zhihu)
• Entity recognition by Chinese AI models (ERNIE, DeepSeek)
• Citations on Chinese forums and industry directories

Each layer builds on the previous one. You can't do AEO without SEO. You can't do GEO without both.

The Practical Playbook

If you're an overseas advertiser targeting China, here's what to do:

Step 1: Get the basics right (SEO)

• Build a Chinese-language landing page (BPP can guide you on this)
• Optimize for Baidu-specific technical requirements
• Start with paid search (Baidu PPC) to generate immediate traffic while organic builds

Step 2: Structure for answers (AEO)

• Add FAQ sections to your Chinese landing pages
• Use Baidu's structured data markup
• Create content that directly answers buyer questions

Step 3: Build authority signals (GEO)

• Establish presence on Zhihu (China's Quora equivalent)
• Create a Baidu Baike entry for your brand (if notable enough)
• Participate in industry discussions on Baidu Tieba and relevant forums
• Ensure your brand is mentioned in Chinese industry publications
