How to Choose Keywords for B2B Export Inquiry Ads: From Purchase Intent to Negative Keyword Selection

Your ads for overseas trade inquiries are getting clicks, but you’re still waiting for qualified leads. The problem may not be that your bids are too low. Procurement managers, students doing research, and consumers looking to buy a single replacement part may all search for the same product term. Choosing the right ad keyword is not about building the largest possible keyword list. It is about identifying people looking for suppliers, then using match types and negative keywords to reserve your budget for those closer to making a purchase.

Assess Purchase Intent Before Search Volume

Take a precision machining company running Google Search ads as an example. “CNC machining” can attract industry traffic, but it does not tell you whether users want to outsource machining. “Custom CNC machining supplier” is more likely to indicate that they are looking for a supplier. To decide whether a keyword is worth targeting, consider it in the context of your actual business: What does the prospect need? How are they planning to buy? Can your factory fulfill the order?

Before building a keyword list, operations staff should confirm three boundaries with the sales team: the materials and processes the factory can handle, the order sizes it can accept, and the countries and regions it can serve. If the factory does not take retail orders, do not add a high-traffic parts keyword to the account based on search volume alone.

These categories are not definitive. An engineer may also research tolerances before shortlisting factories. So, informational searches are not necessarily without value, but they should not compete with clearly purchase-oriented keywords for the same limited budget.

Organize ad keywords into Ad Groups You Can Support

In practice, you can expand your keywords using the formula “product or process + buyer identity + business qualifier.” Buyer identity terms include supplier, manufacturer, and factory. Business qualifiers may include custom, OEM, material names, or industry applications. Do not mechanically combine every possible variation. Keep only the terms that local buyers actually use and that your business can deliver on.

For example, stainless steel part machining and aluminum alloy part machining can be grouped separately by material. But if their selling points, landing pages, and inquiry processes are almost identical, there is no need to split them too extensively. The key question is: Can the keywords in the same ad group use the same accurate ad copy and landing page? If the ad promises custom machining but the page mainly showcases standard parts in stock, the structure needs to be revised.

In multilingual markets, simply translating keywords word for word is not advisable. The terms used for parts, processes, and suppliers can vary by region. Verify them using search results in the target market, sales communication records, and keyword tools rather than relying solely on an English-language keyword list.

Match Types Set the Reach; Search Term Reports Help You Refine It

When budgets are tight and historical data is limited, start by testing core purchase-oriented keywords with exact match and phrase match. Exact match does not trigger only searches that are identical word for word; it may still cover close variants with the same meaning or intent. Phrase match should not be simplistically understood as requiring a search to contain the exact phrase. Use the search terms report to assess the relevance of the traffic you actually receive.

Broad match can help you explore incremental opportunities when conversion tracking is reliable and you have enough room to test, alongside a suitable bidding strategy. If page views or clicks on any button are set as primary conversions in the account, the system may learn to target people who are easy to get clicks from, rather than those who submit valid purchasing inquiries.

Do not increase your budget immediately just because a keyword has a high click-through rate. Compare the search terms with the inquiries: do they include purchasing details such as drawings, materials, quantities, and delivery timelines? A high click volume with few qualified inquiries may be more concerning than a low click volume.

More Negative Keywords Are Not Always Better: Distinguish “Irrelevant” from “Not Yet Converted”

Before launch, prepare a basic negative keyword list, then add to it based on actual searches after the campaign is live. Common areas to check include:

• Education and employment: Tutorials, courses, wages, and job listings. Check the specific terms in the target language.
• Services your business does not provide: Materials or processes you do not support, repair services, or requests to purchase equipment.
• Incompatible transaction models: Single-item retail and second-hand sales, but first confirm whether the business does not handle them at all.

Pay attention to the scope of negative keywords. Terms that are irrelevant to all campaigns can go in a shared list. Terms that conflict with only one product line should be excluded from the relevant campaign or ad group. Otherwise, a decision made for one part of the business could inadvertently affect other lines.

Also, do not automatically exclude every search containing “price”—buyers care about quotes too. Before excluding competitor, location, or price terms, review the full query. Negative keywords in Google Search ads do not automatically cover all close variants, so you may need to add plural forms, spelling variations, and local-language expressions, and check the negative match type.

The Right Keywords Need a Landing Page That Delivers

When buyers search for a custom machining supplier, they usually want to know: “Can you do the work? Why should I trust you? How do I request a quote?” The page should clearly present materials and processes, machining capabilities, and quality control procedures, and provide a convenient way to upload drawings or get in touch. Details such as tolerances and delivery times should reflect your actual capabilities.

For example, the matrix-style product center, credibility-building content, and vertical information layout in the industrial manufacturing showcase solution Precision Machining, Hardware and Fasteners can help organize the browsing journey from product selection to production capabilities and then to contacting the company for a quote. Visual design should support buyers’ evaluation, not leave them searching through the page for technical information.

This is also the value of Yiwangbao’s coordinated planning of intelligent website building and overseas ad campaigns: keywords, ad promises, and landing page content need to align rather than being developed separately and pieced together afterward.

After launch, operations staff should continue tracking the relationship between “search term—page—qualified inquiry” and review performance according to the actual data volume. Prioritize keywords that bring in suitable purchasing inquiries and gradually exclude irrelevant traffic. For keywords with clear intent but no conversions yet, review the page, form, and sales response. The goal is not to produce an impressive-looking keyword list, but to build a customer acquisition journey that can be measured and improved.
