Baidu SEM for B2B: where the leads come from, winning over HQ, and the four phases
Baidu is still China's largest search engine, but B2B brands mostly reach smaller companies there. To win over headquarters, compare SEM with what Google search does for them abroad, then run it in four phases and allow 2–4 weeks to open the account.
Big fish or small fish: what leads does Baidu bring a B2B brand?
Many B2B digital marketing projects never settle one question at the start: is the goal more leads, or carefully landing the "big fish", meaning leads from large enterprises? Growing business with well-known companies and expanding across smaller ones call for completely different methods. Big fish need precise targeting; small fish need a wide net.
On Baidu, most of your target audience will be small and micro businesses. That doesn't mean large clients never search. But when big companies look for a B2B supplier, they usually start from their own supplier lists and business networks rather than searching Baidu from scratch. So when you research your audience personas, find out how they actually search.
Why Baidu is still a must
Baidu is still China's largest search engine. StatCounter puts its share of China's search market at 46.65% across all platforms in September 2026, and 60.15% on mobile. It reaches almost every industry and audience.
Whether you are after small fish or big fish, Baidu is worth the budget. Search is pull marketing: people arrive with a need and search for it themselves, and your ad only has to appear at that moment. If your audience ever searches for contact details or supplier information, you should be there.
How to get the global team to back SEM
One condition first: this conversation only works when senior management is willing to set aside what they already believe and listen. Otherwise even the strongest case goes nowhere. These arguments assume you haven't tried SEM yet and have no data of your own:
- Ask the global team how many leads Google search brings to their website. The answer is usually "a lot", so you can tell them SEM in China can do the same.
- Explain that launching SEM needs no technical support from them, so it adds no work on their side.
- Explain that SEO in China takes heavy investment, works slowly and gives unstable results, so in the short term it usually does less than SEM.
- With SEM running, sales can confidently tell prospects "search for us and you'll find us", instead of being doubted.
- SEM search data shows how customers in the industry search, which feeds back into content.
The four phases of an SEM project: preparation and testing
Search ads go live quickly and show results quickly, but good results still need a phased plan and patience. An SEM project usually has four phases: preparation, testing, optimisation and stabilisation.
Preparation: opening the account
Opening a Baidu account is not as quick as the two or three days sales reps promise. In our experience, getting everything opened and activated usually takes at least 2–4 weeks: document review, internal approvals and Baidu's own inconsistent standards all add time. How long it takes also affects whether your account ends up using web pages or Baidu's Jimuyu pages as landing pages. Foreign companies often run into surprises over their legal representative's documents; a third-party agency can handle this, and the brand only needs to supply the paperwork.
Testing: traffic first
Once the account is ready, you still need keyword structure, ad creative, bidding approach and landing pages. At launch we recommend a larger budget and longer ad schedules, to lay the groundwork for optimising every metric later. This phase is about traffic and gathering enough data, so don't worry about cost per lead yet. If budget is tight, skip oCPC bidding for now and manage bids manually.
Optimisation and stabilisation: from leads to a system
Optimisation: conversions first, control costs
Now the aim is more leads from your ads, not just traffic. Narrow the traffic and focus on the cost and number of leads: cut budget on low-converting keywords and move it to the ones that convert. At the same time, make the team more efficient, for example in content updates and design.
Stabilisation: connect the data
First ask whether the current campaigns still have room to improve. If not much, connect your Baidu lead data to SCRM so you can see leads from every digital channel in one place and follow what happens to each one. This is the step that changes things fundamentally.
| Phase | Focus |
|---|---|
| Preparation | Setting up the account |
| Testing | Traffic first |
| Optimisation | Conversions first, cost control, team processes |
| Stabilisation | Building the system |

FAQ
How long does it take to open a Baidu ads account?
In our experience, at least 2–4 weeks to have everything opened and activated, not the two or three days sales reps mention. Document review, internal approvals and Baidu's checks all add time, and foreign companies' legal-representative documents often cause delays.
Do large companies search Baidu for suppliers?
Some do, but not many. Large companies usually start from their own supplier lists and networks, so the B2B audience on Baidu is mostly small and micro businesses. Landing big accounts needs more targeted channels alongside search.
Should I use oCPC bidding from day one?
Not necessarily. The testing phase is about traffic and data, so on a tight budget bid manually first and consider oCPC once you have enough data and move into optimisation.
