In digital marketing, Baidu Promotion has long been an important channel for enterprises to acquire precise traffic, but many companies face the same confusion: plenty of clicks but few inquiries; and when inquiries do come, conversion cannot keep up. In serving small and medium-sized enterprises across China, Yunxuan Network Technology has found that the problem often lies not in the size of the budget, but in whether the customer acquisition funnel is closed-loop. Today, we will break down the combined approach of 'Baidu Promotion + AI agents' and explain our service thoroughly from three dimensions: process, who it suits, and value.
1. Baidu Promotion Is Not Just Buying Keywords; It Is Building a Conversion Funnel
When many clients come to us, their first sentence is: 'Help me open a Baidu Promotion account and bid on some keywords.' But the essence of Baidu Promotion is paid traffic procurement. Whether traffic can become inquiries after it arrives depends on reception capability. Yunxuan Network Technology's approach is to first sort out the business logic, then design the promotion structure, and finally use tools to receive traffic, forming a closed loop of 'impression-click-inquiry-lead capture-follow-up.'
1.1 Account Setup: Working Backward from Business Goals to Promotion Structure
We do not simply apply templates. Take an engineering company as an example: the client's core business is factory building construction, and the target customers are heads of manufacturing factories. We first analyze its average order value, sales cycle, and decision-making chain, then determine the promotion goal: brand exposure, lead collection, or direct phone inquiries. Based on the goal, we build the account structure: campaigns are divided by product line (such as factory construction, cleanrooms, and steel structure engineering), ad groups are grouped by keyword intent (such as 'factory construction company' and 'cleanroom decoration'), and different ad copy and landing pages are matched. The purpose is to ensure every bit of budget is spent on search terms that may lead to a deal.
1.2 Keyword Strategy: Not More Is Better, but More Precise Is Better
Baidu Promotion offers three keyword match types: exact, phrase, and broad, and bidding strategies include manual and automated. In operation, Yunxuan Network Technology combines industry keyword libraries and client historical data to screen high-conversion terms, long-tail terms, and negative keywords. For example, terms such as 'price' and 'how much' often have higher conversion rates, but the landing page needs clear pricing or case studies; terms such as 'manufacturer' and 'supplier' are suitable for factory-type clients. We also regularly review search term reports and add irrelevant terms as negatives to avoid invalid clicks. For nationwide businesses, we adjust bids based on regional performance, but we do not bid only in the local area just because our office is located there—serving clients nationwide is our basic positioning.
1.3 Landing Page Design: The First Frontline for Receiving Traffic
The landing page is the main conversion battlefield of Baidu Promotion. When building websites for enterprises, Yunxuan Network Technology specifically designs high-conversion landing pages for promotion rather than directing users to the official website homepage. A landing page needs several elements: clear selling points (what problem is solved), trust endorsements (cases, qualifications, customer reviews), calls to action (forms, phone, online consultation), and fast loading speed with good mobile adaptation. We once served a manufacturing factory whose original landing page was a product list with a high bounce rate; after changing it to a 'solution + cases + inquiry form' structure, the number of inquiries nearly doubled.
2. AI Agents: Making Inquiry Conversion No Longer Dependent on Manual Online Hours
After traffic arrives, if customer service is offline, responds slowly, or uses unprofessional scripts, customers will be lost. Especially for nationwide businesses, time zone and schedule differences often lead to nighttime inquiries going unanswered. The AI agent launched by Yunxuan Network Technology is designed to solve this pain point—it is not a simple auto-reply robot, but an intelligent reception assistant trained on the enterprise knowledge base, capable of receiving inquiries 24/7, guiding lead capture, and screening potential customers.
2.1 The Role of AI Agents in the Baidu Promotion Funnel
When a user clicks a Baidu Promotion ad and enters the landing page, the AI agent proactively opens a chat window and initiates a topic based on the page content the user is viewing. For example, if the user is browsing a 'factory construction' page, the agent asks: 'Do you need to build a new factory or renovate one? Roughly how large is the area?' Through multi-turn dialogue, the agent can determine the user's intent level and guide the user to leave contact information or transfer directly to a human. At night or on holidays, the agent can handle reception independently and sync conversation records and customer information to the sales team, so they can follow up first thing the next morning.
2.2 Core Capabilities of AI Agents
- Enterprise-specific knowledge base: Import product materials, cases, price ranges, and FAQs, and the agent's answer accuracy can reach over 90%.
- Multi-turn dialogue and intent recognition: It can gradually uncover needs based on user answers rather than giving mechanical replies.
- Lead capture guidance and form filling: It naturally guides users to leave a phone number or WeChat during the conversation and automatically fills in the form.
- Seamless transfer to human agents: For complex issues or high-intent customers, one-click transfer to human customer service avoids loss.
- Data retention and analysis: All conversation records can be traced, helping enterprises optimize scripts and promotion strategies.
2.3 Which Enterprises It Suits
AI agents are especially suitable for the following scenarios: limited customer service manpower, many nighttime inquiries, highly repetitive product consultation questions, and enterprises that need nationwide customer acquisition but cannot set up customer service teams in every region. Examples include engineering, manufacturing, trade and wholesale enterprises, as well as local life service merchants. When Yunxuan Network Technology served an engineering enterprise in Zhanjiang, after launching the AI agent, the lead capture rate of nighttime inquiries increased by 60%, and the sales team's follow-up efficiency the next day improved significantly.
3. Baidu Promotion + AI Agents: 1+1>2 Inquiry Conversion Results
With Baidu Promotion alone, traffic comes in but reception cannot keep up, resulting in low conversion rates; with AI agents alone, no traffic comes in and the tool runs idle. Only by combining the two can a closed loop be formed. When serving clients nationwide, Yunxuan Network Technology usually recommends that enterprises deploy Baidu Promotion and AI agents simultaneously and connect them at the data level.
3.1 Data Integration: Full-Funnel Tracking from Click to Deal
We deploy conversion tracking code on enterprise landing pages to record the entire process from ad click to conversation, lead capture, and deal. By comparing data from Baidu Statistics and the AI agent backend, we can analyze which keywords bring high-quality conversations, which landing pages have higher lead capture rates, and which time periods have better inquiry conversion. These data in turn guide optimization of the promotion account, such as increasing bids on high-conversion terms and pausing terms that receive clicks but no inquiries.
3.2 Script Optimization: Using Real Conversations to Improve Ad Copy
The conversation data accumulated by AI agents is a valuable asset. Yunxuan Network Technology regularly analyzes users' high-frequency questions, such as 'How long is the construction period?' 'Do you include installation?' and 'Do you have cases?' Then we distill the answers to these questions into ad copy and landing pages, so users can obtain key information before clicking, improving click quality. At the same time, the agent's scripts are continuously iterated based on user feedback to improve lead capture rates.
3.3 Human-AI Collaboration: Prioritizing High-Intent Customers
AI agents do not replace humans; they screen and assist. The agent tags customers based on conversation content, such as 'high intent—phone number left,' 'medium intent—comparing prices,' and 'low intent—just asking.' The sales team can prioritize high-intent customers and avoid wasting time. For nationwide businesses, the agent can also assign users to sales representatives in the corresponding region based on location, improving follow-up efficiency.
4. Pitfall Guide: Five Common Misconceptions About Baidu Promotion and AI Agents
In serving clients, we have seen many enterprises take detours. Here we summarize five common misconceptions for reference.
Misconception 1: Focusing Only on Cost per Click and Ignoring Cost per Conversion
Some enterprises blindly pursue low cost per click, which attracts a large amount of irrelevant traffic and actually increases conversion costs. The correct approach is to focus on 'cost per conversion,' that is, the average spend to obtain one inquiry. When optimizing accounts, Yunxuan Network Technology uses cost per conversion as the core metric to adjust bids and match types.
Misconception 2: Using the Official Website Homepage Directly as the Landing Page
The official website homepage carries the brand image and contains a large amount of information with scattered focus, making it unsuitable as a promotion landing page. A promotion landing page should focus on a single conversion goal and highlight selling points and calls to action. We recommend that enterprises design separate landing pages for each promotion campaign and combine them with AI agents to create a coherent 'ad-landing page-agent' experience.
Misconception 3: Setting Up the AI Agent and Then Ignoring It
AI agents require continuous training and optimization. Enterprise businesses change, customer questions update, and the agent's knowledge base and scripts must be updated regularly. Yunxuan Network Technology provides clients with monthly AI agent operation reports, including conversation volume, lead capture rate, high-frequency questions, and human transfer rate, along with optimization suggestions.
Misconception 4: Believing AI Agents Will Replace Human Customer Service
The role of AI agents is 'intelligent reception + preliminary screening.' Complex issues, negotiations, and after-sales service still require human handling. Our experience is that agents handle 70% of routine inquiries and humans handle 30% of high-value inquiries, achieving the highest human-machine collaboration efficiency.
Misconception 5: Opening a Promotion Account and Then Leaving It Alone
Baidu Promotion requires continuous optimization, including keyword adjustments, bid optimization, ad copy updates, and landing page iterations. Yunxuan Network Technology provides bid management services, with professional optimizers formulating monthly optimization strategies to ensure stable account performance. For enterprises without a dedicated promotion team, managed services are a more worry-free and efficient choice.
