The remaining 30% can cover niche terms. This targeting approach typically produces 2-3x better ROAS than broad-category bidding.
## How Chinese B2B Buyers Actually Search and Decide
Understanding search behavior is the difference between running ads and running profitable ads. Baidu's report maps the exact journey Chinese B2B buyers take from first search to final purchase.
### The Search Journey: Three Stages
**Stage 1 β Awareness**: Buyers start with generic B2B terms. They are casting a wide net. At this stage they click on Baidu Baike entries, Baidu Zhidao Q&A, and industry content on Baijiahao. They are educating themselves β not yet ready to contact a supplier.
**Stage 2 β Comparison**: Searches narrow to specific manufacturers and sources. Terms like "factory direct," "manufacturer," and "wholesale supplier" dominate. Buyers now click on B2B platforms, company websites, and technical support pages.
**Stage 3 β Decision**: The final phase. Buyers search for transaction terms β pricing, minimum order quantities, shipping. They visit AiCaiGou, 1688.com, and supplier websites to place inquiries.
The takeaway for advertisers: your search campaigns need to match the buyer's stage. A broad industry keyword and a transaction-focused keyword should lead to different landing pages and different calls to action.
### What Buyers Care About Most
Across all industries, one factor dominates B2B purchase decisions more than any other: **price**. Chinese business buyers research pricing before anything else β before specifications, before supplier reputation, before delivery terms.
But secondary concerns vary by industry:
- **Building materials and metals**: word-of-mouth reputation, returns and repairs
- **Machinery, electrical, and electronics**: resale and rental options
- **All industries**: transaction channel reliability and payment security
### When and Where Buyers Search
**Time patterns**: PC searches peak on workdays during office hours. Mobile searches are more evenly distributed β including weekends and evenings. This means B2B campaigns should run across the full week, with budget allocated to capture weekend mobile traffic that competitors often miss.
**Regional patterns**: East China accounts for 50% of all B2B search demand. North China and South China each contribute around 12%, Central China 10%, with smaller shares from Southwest (5%), Northeast (5%), and Northwest (4%). Within South China, Guangdong province alone dominates the region's B2B activity.
"Demand is concentrated in East China, where economic activity is most intense. But different industries show different regional patterns β logistics and auto parts have outsized demand in Guangdong, Hubei, Sichuan, and Hebei, while consumer electronics demand peaks in Guangdong, Sichuan, and Henan." β 2020 Baidu B2B Industry Insights Report## The B2B Platform Landscape: Who Is Winning Baidu's report segments B2B platforms into two models: - **Comprehensive platforms** (78% of search interest): 1688.com, AiCaiGou (Baidu's own platform), HC360.com β one-stop platforms with broad category coverage - **Vertical platforms** (22%): Industry-specific marketplaces with deeper domain expertise 1688.com leads in both search volume and brand recognition.
