If you spend marketing budget in China, you have probably noticed something has changed. The old playbook of "bid on keywords, rank first, watch conversions roll in" is losing its edge. Two major white papers released in May 2026 — from iResearch (艾瑞咨询) and iMedia (艾媒咨询) — put hard numbers behind what many advertisers are already feeling on the ground.
The bottom line: AI-driven marketing is no longer a nice-to-have. It is the new cost of entry.
Let us walk through the data and, more importantly, what it means for international brands advertising on Baidu.
The Numbers That Changed Everything
90B+ RMB
GEO market size (2026e, +70% YoY)
800M+
Monthly active AI search users in China
60%+
Users consulting AI before purchase decisions
-30%
Traditional SEO traffic decline (YoY)
These four numbers tell one story: the Chinese consumer's path to purchase is being rebuilt around AI. Eight hundred million people are now using AI search tools monthly. More than half of them ask AI for recommendations before buying. Meanwhile, clicks from traditional search results are dropping by nearly a third year-over-year.
For international brands, this is both a threat and an opportunity. The threat: if your content is not optimized for AI-driven discovery, you are invisible to a growing share of the market. The opportunity: the brands that adapt first will capture audience share that competitors are passively abandoning.
GEO: The New SEO — And It Is Growing at 70% Year-Over-Year
The white papers introduce a term that every marketer in China needs to understand: GEO (Generative Engine Optimization). It is not a rebranded version of SEO. It is a fundamentally different approach.
| Dimension | Traditional SEO | GEO (2026) |
|---|---|---|
| Optimization target | Web page ranking | Semantic credit — being cited by AI models |
| Core mechanism | Keyword matching | Entity relationship + intent matching |
| Cost per lead | Baseline | 38.4% lower |
| Traffic trend | Declining 30%+ YoY | Growing with AI search adoption |
What this means for Baidu advertisers: GEO is not replacing Baidu PPC. It is reshaping the landscape around it. When users consult AI before searching — and 60% now do — your paid ads compete in a smaller attention pool. The brands that build GEO readiness alongside their PPC campaigns will see better ROI on both channels.
Real-World Results: AI Marketing in Action
The white papers include case studies that put real numbers behind the AI marketing trend:-28%
Customer acquisition cost (manufacturing case)
3.5x
Increase in sales leads (same case)
3.2x
Customer reach efficiency (financial services)
-47%
Reduction in invalid inquiries
The Three Drivers Behind the Shift
The white papers identify three structural forces pushing AI marketing from optional to essential:1. User Behavior Has Crossed the Tipping Point
With 800 million monthly active AI search users and 60%+ of consumers consulting AI before buying, the old model of "search, click, convert" is fragmenting. Users no longer start their journey on Baidu. They start with an AI assistant — and by the time they search, they have already formed opinions.2. Traditional Marketing Efficiency Is Declining
The white papers are blunt on this point: traditional SEO traffic has declined more than 30% year-over-year. Keyword bidding costs continue to rise while conversion rates stagnate. The arbitrage that used to work — buy traffic cheap, convert at a decent rate — is no longer viable.3. Technology Has Reached Production Quality
AI marketing tools are no longer experimental. With 92%+ intent recognition accuracy, sub-200ms response times, and the ability to handle 80%+ of common inquiries automatically, AI customer service and AI-driven ad optimization are ready for production deployment — including on Baidu's platform.The cost of waiting: The white papers identify a "logical anchoring effect" — when a brand's AI model citation rate reaches 22.4% in its vertical, the AI system automatically classifies it as an authoritative source, and subsequent citation probability grows exponentially. Brands that move first build a semantic moat that is increasingly expensive for competitors to cross.
What This Means for Baidu Advertisers
Baidu is not standing still while this transformation unfolds. The platform has already deployed AI across every layer of its advertising ecosystem: - Smart bidding: Real-time bid optimization based on conversion probability, competition, and user context - Smart creative: AI-generated ad copy and visuals tailored to individual user intent - Merchant Agent (商家智能体): AI-powered customer interaction that handles inquiries 24/7, with human handoff for complex cases - Industry Insights: Benchmark dashboards showing your performance against competitors, with conversion target recommendations The key insight from the white papers is that using these tools is no longer optional. Companies running Baidu campaigns without AI optimization are seeing their conversion costs rise 25-40% year-over-year. Companies that adopt AI tools are cutting costs and improving lead quality.Three Actions for International Brands
Based on the white paper findings, here is what overseas companies should prioritize right now:1. Activate Baidu's AI Advertising Tools
If your Baidu campaigns are still running on manual bidding with standard ad copy, you are leaving money on the table. Baidu's smart bidding and smart creative tools are available to all advertisers — and they are already producing measurable results for companies that use them.2. Build Your GEO Foundation
GEO is not a replacement for PPC — it is a complement. Start by ensuring your brand information is structured, accurate, and consistent across Baidu's ecosystem. This includes your official website, Baidu Baike, industry media, and your Baidu advertising account. AI models pull from all of these sources when generating answers.3. Deploy AI Customer Service
The Merchant Agent is Baidu's most under-utilized tool among international advertisers. It handles routine inquiries automatically, qualifies leads before they reach your sales team, and operates in Chinese 24/7. For overseas companies without a local team, this bridges the most critical gap.🎯 Key Takeaways
