Google Ads for B2B: how to get qualified leads, not clicks

Many industrial and B2B companies have tried Google Ads once and stopped: plenty of clicks, a few odd calls, no orders. The platform was rarely the problem. The campaign was built for clicks, not for buyers. This guide covers how we set up paid ads for B2B companies so the budget goes to people who might actually buy.

What makes B2B search ads different?

Consumer advertising	B2B advertising
Many searches, low ticket	Few searches, high ticket
Purchase in minutes	Sales cycle of weeks or months
One decision-maker	Buyer, engineer and management decide
Success = online sale	Success = qualified lead, then a deal
Broad audiences	Narrow, specific search terms

Because volume is low and each lead is valuable, every wasted click hurts more, and the metric that matters is not click-through rate but cost per qualified lead.

Why set up conversion tracking first?

Google Ads optimizes toward whatever you tell it is a success. If nothing is tracked, it optimizes toward clicks, which in B2B means students, job seekers and competitors. Before launching, track as conversions:

• Quote request and contact form submissions.
• Calls from ads and calls from the website.
• Chat or WhatsApp clicks, where relevant.
• Drawing or file uploads.

Then import the outcome when you can: which leads sales marked as qualified. Even a monthly spreadsheet that maps leads to deals tells you which keywords bring business.

Which keywords should a B2B campaign target?

Separate keywords by intent:

Intent	Example searches	What to do
Buying	“cnc machining services near me”, “custom gear manufacturer”	Core campaigns, highest bids
Researching	“what is 5-axis machining”, “laser vs plasma cutting”	Content and articles, not ads
Jobs and training	“cnc machinist jobs”, “cnc course”	Negative keywords
DIY and free	“free cad software”, “how to build a gearbox at home”	Negative keywords

Google offers three match types. Exact match shows ads for searches with the same meaning as the keyword; phrase match for searches that include its meaning; broad match for related searches. Start with phrase and exact match to control spend, then test broad match once conversion data is reliable.

Why are negative keywords so important?

In B2B, a large share of searches that contain your keywords are not buyers. A machining company that bids on “cnc” without negatives will pay for “cnc jobs”, “cnc course” and “cnc router for hobby”. Build a negative list before launch and review the search terms report every week for the first month:

• Jobs: job, career, salary, hiring, vacancy.
• Education: course, training, tutorial, pdf, school.
• Free and DIY: free, homemade, diy, how to make.
• Wrong products or markets: brands you do not serve, consumer versions.

What should the landing page do?

The ad is a promise; the landing page has to keep it. Sending every ad to the home page is the most common reason for clicks without leads. Each ad group should land on a page about exactly what the ad said, with:

• The service or product in the headline, matching the search.
• Capabilities, materials and limits that let the buyer qualify you.
• Proof: industries served, cases, certifications.
• A short form with file upload, and a phone or chat option, visible without scrolling.

Landing page relevance also feeds Google’s Quality Score, which affects how much you pay per click. Our checklist for industrial websites covers what those pages need.

How should the campaign be structured?

A simple, controllable structure beats a clever one:

• One campaign per service or product line, each with its own budget.
• Small ad groups of closely related keywords, each with its own landing page.
• Location targeting that matches where you actually deliver.
• Ad schedule focused on business hours if leads need a quick call back.
• Remarketing to visitors who saw a service page but did not convert.

Which numbers should you review every month?

Metric	Question it answers
Spend by campaign	Where is the money going?
Conversions by campaign	Which services bring leads?
Cost per lead	What does a lead cost, per service?
Qualified leads (from sales)	Which leads were real opportunities?
Search terms	Which searches should become negatives?
Landing page conversion rate	Is the page or the traffic the problem?

Review these with sales, not only with marketing. A campaign with cheap leads that never become deals is worse than one with expensive leads that close.

What are the most common mistakes?

• Letting Google pick everything from day one. Fully automated campaigns without conversion data spend on whatever gets clicks.
• Bidding on your own field’s generic words. “CNC”, “machining” or “steel” alone attract students, jobs and hobbyists. Add context: service, application, region.
• No negative keywords. In B2B this alone can waste a large share of the budget.
• Judging by clicks or CTR. A campaign with many cheap clicks and no leads is failing, however good the dashboard looks.
• Not answering fast. A lead that waits a day for a reply often went to the next supplier. Paid leads deserve the fastest response.
• Changing everything every week. Campaigns need time and data to stabilize. Change one thing, measure, then change the next.

A launch checklist

• Conversions tracked: forms, calls, chat, file uploads.
• Keywords grouped by service, with buying intent.
• Negative keyword list in place (jobs, training, free, DIY).
• One landing page per ad group, with a short form above the fold.
• Location and schedule match how you sell.
• Monthly report agreed: spend, leads, cost per lead, qualified leads.

Built this way, paid search becomes a predictable source of quote requests instead of a cost nobody can explain.
