After 20 years in internet services, we've seen too many companies pour budgets into Baidu promotion and end up with barely any calls. We've also seen brand promotion spread across countless channels while customers still can't remember who you are. And sometimes inquiry volume does rise, but sales complains that 'lead quality is poor.' The problem usually isn't any single step—it's that the entire customer acquisition chain isn't connected. Today, from the perspective of a service provider, Yunxuan Network Technology will break down Baidu promotion, AI customer service, and brand promotion, and share practical experience from serving SMEs nationwide to explain how to do it and what to watch out for.
1. Baidu Promotion: Don't Rush to Bid—First Figure Out How to 'Catch' the Leads
Many companies come to us to open a Baidu promotion account and the first thing they say is, 'Get it running as fast as possible.' But we usually ask three questions first: Can your landing page match search intent? Is someone available in real time to handle inquiries? Once a lead comes in, who follows up and how soon? Without answers to these three questions, the harder you push promotion, the faster you waste money.
1.1 Account Structure Determines Whether You Can 'Spend Right'
Baidu promotion isn't about having as many keywords as possible. When we diagnose accounts for clients nationwide, the most common problem is a huge pile of keywords all using broad match. As a result, someone searching for 'industrial wastewater treatment equipment' lands on a generic 'environmental equipment manufacturer' page, realizes it's not what they need, and leaves—money wasted. The right approach is to group by business line, region, and buying stage. For example, a company selling engineering materials should place 'XX material price,' 'XX material manufacturer,' and 'XX material construction plan' in different ad groups with different creatives and landing pages. People searching for 'price' need to see pricing logic and case studies; people searching for 'construction plan' need to see technical strength and service process. The finer the grouping, the more accurate the creative, the higher the quality score, and the better the ranking at the same bid—actually lowering cost per click.
Also, bidding strategies for nationwide promotion and local promotion are completely different. Companies doing nationwide business that only target a few major cities miss a lot of precise demand in second- and third-tier cities. Local service businesses that open nationwide bidding attract many invalid clicks. We generally recommend clients start with small-scale tests, let data speak, and then scale up gradually.
1.2 A Landing Page Isn't an 'Online Business Card'—It's a 'Salesperson'
For Baidu promotion landing pages, many companies just use their homepage. A homepage is for branding; a landing page is for search intent. If a user searches 'Zhanjiang steel structure factory cost' and you take them to a company profile page, they won't find the answer and will leave. When we build landing pages for clients, we usually follow several principles: the first screen directly addresses the search term, explaining in one sentence what you do and what problem you solve; the middle section shows cases, qualifications, and service process to build trust; the bottom offers forms, phone numbers, and online chat to lower the barrier to action. Mobile is especially important—if loading takes more than 3 seconds, half the visitors are already gone.
One more thing easily overlooked: the landing page must connect with the AI customer service that follows. If a user has a question after viewing the page, opens the chat window, and sees a cold 'Please leave a message,' conversion will drop sharply. This leads to the next key step.
2. AI Customer Service and AI Agents: Make Sure Every Inquiry Gets 'Answered'
We served an equipment rental company that ran Baidu promotion for a month. The backend showed good clicks, but very few form submissions. We found that their online chat only had human staff during working hours. Visitors at night and on weekends saw 'Customer service offline' and simply closed the window. Yet the search peak for equipment rental was exactly after work hours. Later we helped them launch an AI agent customer service, and the situation changed completely.
2.1 Smart Customer Service Isn't 'Auto-Reply'—It's 'Automated Lead Generation'
There are many auto-reply tools on the market, but most can only do simple keyword matching. If a customer asks, 'What advantages do you have compared to XX?' it can't answer. The AI agent built by Yunxuan Network Technology is based on large model capabilities. It can understand context, answer complex questions, judge intent level based on customer questions, and proactively guide lead capture. For example, if a customer asks, 'Do you serve nationwide?' the agent answers with the service scope and then asks, 'Which city are you in? If you leave a contact, I'll have the regional consultant send you case studies.' This isn't mechanical replying—it's strategic reception.
After deploying an AI agent for a manufacturing factory, the lead capture rate for nighttime inquiries increased noticeably. The agent doesn't get tired, doesn't miss messages, doesn't have a bad attitude, and maintains a consistent script standard 24/7. For SMEs with limited budgets that can't afford night-shift customer service, this is a highly cost-effective customer acquisition tool.
2.2 Smart Customer Service Must 'Coordinate' with Baidu Promotion
Traffic from Baidu promotion has clear intent but limited patience. If a user clicks in and doesn't get an effective response within 30 seconds, they'll click the next ad. So when we set up promotion accounts, we simultaneously configure the AI customer service welcome message and guiding script. For example, for customers searching 'XX equipment manufacturer,' the welcome message directly says, 'Hello, we are a source manufacturer of XX equipment, shipping nationwide. Could you tell us your needs?' This lets the customer know they've come to the right place and are willing to continue. For those searching 'XX equipment repair,' the welcome message changes to, 'Hello, we provide nationwide on-site repair service. Which city is your equipment in?' When the script follows the search term, conversion rates are completely different.
In addition, the customer questions collected by the AI customer service are valuable material for optimizing Baidu promotion. If customers repeatedly ask about 'price,' 'lead time,' or 'after-sales,' it means the landing page isn't clear or the creative guidance is off. We regularly feed these high-frequency questions back into account optimization, forming a closed loop of 'promotion traffic—AI reception—data feedback—promotion optimization.' Only when this loop runs will customer acquisition costs gradually decline.
3. Brand Promotion: Make Customers Trust You Before They Even Search for You
Baidu promotion solves 'people with a need right now find you.' Brand promotion solves 'people with a future need remember you.' The two aren't either/or—they work together. If you only do promotion without brand, you have no pricing power when customers compare. If you only do brand without promotion, you can't handle the traffic when demand surges.
3.1 The 'Foundation' of Brand Promotion Is Your Website and Content
We often tell clients that the official website is the 'headquarters' of brand promotion. No matter how much content you put on Douyin, Baidu, Zhihu, or Xiaohongshu, customers will eventually search your company name and check the website. If the site loads slowly, looks outdated, and hasn't been updated in years, all the exposure before that is discounted. Yunxuan Network Technology builds corporate websites not just to look good, but to build a solid underlying architecture that Baidu can index, AI can crawl, and mobile devices can open smoothly. This is the infrastructure of brand promotion.
On the content level, we recommend companies lay out content around the customer decision path. From 'not knowing you' to 'asking you for a quote,' customers search many terms: industry questions, solutions, product comparisons, company reputation. Brand promotion isn't just pushing your company name—it's covering content at all these decision points. For example, an environmental engineering company can write 'Common Misconceptions in Wastewater Treatment,' 'Equipment Selection Guide,' and 'Project Acceptance Standards.' This content can be indexed by Baidu for organic traffic and also provides professional endorsement when customers compare.
3.2 Multi-Channel Brand Exposure Needs 'Priorities'
There are too many channels now—Douyin, Video Account, Baidu, Zhihu, industry platforms. Companies can't do them all well. Our advice: first determine where your customers mainly are, then decide which two channels to focus on. For nationwide B2B business, Baidu and vertical industry platforms are key. For local life services, Douyin local life and Baidu local promotion are key. Go deep in the main channels, maintain a presence in secondary channels, and don't spread effort evenly.
Short videos have been the most asked-about in the past two years. Many companies give up after a few videos don't work. The problem is usually that the content is too 'official'—leadership speeches, company tours, product displays. Customers don't care about that. They care about 'what problem can you help me solve.' When we did short video lead generation for a trading store, the content was all 'How to Choose XX,' 'Three Uses of XX,' and 'Answers to Common Customer Questions.' People naturally asked for prices in the comments. Short videos aren't for peers—they're for potential customers.
3.3 GEO Generative Engine Optimization: A New Battleground for Brand Promotion
This is a change that's happening now. More and more customers ask AI first before buying equipment or finding services—Doubao, Qwen, DeepSeek. If your brand information isn't indexed by these AI platforms, when a customer asks 'Which company in XX industry is reliable?' the AI won't mention you. Yunxuan Network Technology's GEO generative engine optimization helps companies place brand content, cases, and Q&A where AI can crawl and understand, so enterprises can be 'recommended' in the AI search era. This differs from traditional SEO logic, but the foundation is still content quality and authority. Companies that lay out early will enjoy a wave of dividends.
4. Connecting the Three: What a Complete Customer Acquisition Loop Looks Like
After all this, Baidu promotion, AI customer service, and brand promotion aren't three separate projects—they're three links in one chain. When we provide full digital marketing managed services for clients nationwide, we usually connect them like this:
- Step 1: Build the website and lay the content foundation. Create a website that Baidu can index, AI can crawl, and mobile users can enjoy, while preparing core business content materials. This is the 'ammunition depot' for all promotion.
- Step 2: Precise traffic acquisition via Baidu promotion. Build accounts by business line and region, control costs with precise keywords and match types, and design landing pages specifically for search intent instead of using the homepage.
- Step 3: AI customer service and AI agents handle reception. Respond 24/7, automatically answer common questions, proactively guide lead capture, and squeeze full value from every inquiry. Night and weekend traffic is no longer wasted.
- Step 4: Brand promotion continuously stores water. Lay out content on short video, industry platforms, AI search, and other channels so customers build awareness before they have a need. When brand promotion is done well, Baidu promotion conversion also rises because customers already have a trust foundation when they find you.
- Step 5: Data review and optimization. Look at promotion data, customer service conversations, and deal records together to find where the most loss occurs and improve accordingly. Only when this loop turns will customer acquisition costs continue to decline.
One Zhanjiang engineering company we served initially only did Baidu promotion, and inquiry volume was unstable—sometimes good, sometimes bad. Later we rebuilt their website, split landing pages by business line, launched AI agent customer service, and created brand content on industry platforms and short video channels. Three months later, not only did Baidu promotion inquiries rise, but inquiries from organic search and AI recommendations also increased. More importantly, sales reported better lead quality because customers had already seen case studies and qualifications before contacting them, greatly reducing communication costs.
5. Several Pitfall Warnings for SMEs Nationwide
Finally, based on our experience serving clients nationwide, here are a few common pitfalls.
First, don't treat Baidu promotion as a 'lifeline.' Promotion is an amplifier, not an engine. If products, services, landing pages, or customer service are lacking, promotion only amplifies problems—it doesn't solve them. Fix the weak links first, then scale.
Second, smart customer service isn't done once you buy it. AI agents need continuous training and optimization. Customer phrasing changes, and scripts must change too. We generally recommend clients review conversation logs once a week and add poorly answered questions so the agent gets smarter over time.
Third, don't chase 'viral hits' in brand promotion. Brand is long-term accumulation—it can't be built with one video. Consistently producing content useful to customers is more important than an occasional viral hit. This is especially true for nationwide promotion; customers in different regions care about different things, so content must be targeted.
Fourth, don't ignore the balance between local lead generation and nationwide promotion. Many companies do local business and also want to expand nationwide. Our advice is to operate separately: local promotion uses local scripts and local cases; nationwide promotion uses nationwide service capability and logistics/after-sales guarantees to ease customer concerns. Mixing them pleases neither side.
Fifth, look at data across the 'full chain.' Looking only at clicks and impressions is meaningless. Look at conversion rates from click to inquiry, inquiry to lead, and lead to deal. Optimize whichever step drops the most.
