Google Ads works for B2B. It just doesn't work the way Google's own onboarding wizard tells you to run it. Follow the defaults and you'll burn budget on broad-match traffic, irrelevant clicks, and conversions that look fine on a dashboard and never reach a salesperson.

This is the playbook we use to run profitable B2B search campaigns — the structure, the targeting decisions, the bidding choices, and the measurement that tells you whether any of it produced revenue. It assumes long sales cycles, high deal values, and a buying committee, because that's what B2B actually looks like.

Why B2B Google Ads is different

The mechanics are the same as B2C. The economics are not. A B2B deal might be worth £30,000 in first-year revenue and far more over its lifetime, so you can afford a cost per click and cost per lead that would bankrupt a transactional business. But the search volume is thinner, the intent is harder to read, and the gap between a click and closed revenue is measured in months, not minutes.

That combination — high value, low volume, long lag — changes every decision. You optimise for qualified pipeline, not conversions. You bid for intent, not traffic. And you measure on a timeline that matches your sales cycle, not the 30-day attribution window Google reports by default.

Campaign structure that holds up

Google pushes you towards consolidated, automated campaigns because that suits its algorithm. For B2B, that consolidation hides the signal you need. Structure your account around intent tiers instead.

Tier one: high-intent commercial terms

These are the searches where someone is actively looking to buy or compare: "{your category} software", "{competitor} alternative", "{service} provider UK". They convert best, cost most, and deserve the bulk of your budget. Keep them in tightly themed ad groups so your ad copy and landing page match the exact query.

Tier two: problem-aware terms

Searches that describe the problem you solve rather than your product: "how to reduce customer churn", "manual invoice processing errors". Intent is lower, volume is higher, and the right destination is usually a resource or a problem-led landing page, not a demo request. This tier feeds your pipeline over time.

Tier three: brand defence

Bidding on your own brand name feels like paying for traffic you'd get free. It isn't. Competitors bid on your brand, and the cost to defend it is trivial. A few pounds a day keeps your message at the top when someone searches for you specifically. Skip it and you hand warm prospects to whoever outbids you.

"In B2B search, the goal isn't more clicks. It's the right clicks from the small number of people who can actually buy — and ruthless exclusion of everyone else."

Match types and the broad-match trap

Google now nudges every advertiser towards broad match plus Smart Bidding, promising the algorithm will find your buyers. For high-volume B2C, that often works. For low-volume B2B, broad match floods your account with loosely related searches, drains budget before your real buyers ever see an ad, and trains the algorithm on junk conversions.

Start with phrase and exact match on your tier-one terms. Use broad match only once you have a strong conversion signal feeding the algorithm, and only with a tight negative keyword list policing it. Treat broad match as something you earn, not something you start with.

Negative keywords: the unglamorous edge

Negative keywords are where B2B accounts are won or lost, and almost nobody gives them the attention they deserve. Your buyers and the general public search the same words for different reasons. Someone searching "free", "jobs", "salary", "course", "template", or "wikipedia" alongside your terms is almost never a buyer.

  • Build a standing negative list of job-seeker terms: "jobs", "salary", "career", "vacancy", "intern".
  • Exclude free-intent modifiers: "free", "cheap", "diy", "template", "open source".
  • Add educational and research terms if they don't fit your intent: "course", "certification", "definition", "meaning".
  • Review the search terms report weekly for the first three months, then monthly. Add negatives every time.

A disciplined negative list routinely cuts wasted spend by 20–30% in the first quarter. It's the fastest way to lower cost per qualified lead, which we cover in depth in how to lower your B2B cost per lead .

Bidding for pipeline, not conversions

Smart Bidding optimises towards whatever conversion you feed it. Feed it form fills and it will get you cheaper form fills — including the ones from students, competitors, and tyre-kickers. That's how B2B accounts end up with a falling cost per lead and a flat pipeline.

The fix is to feed the algorithm a conversion that actually matters. Pass offline conversions back from your CRM — a qualified opportunity, or better, closed revenue — so Smart Bidding learns what a real buyer looks like, not just what a form-filler looks like. This single change reorients the entire account towards pipeline. It takes setup work to connect your CRM, and it's the highest-leverage thing you can do. We explain the reporting foundation in reporting and analytics .

Landing pages: where the budget is wasted

The most common reason B2B Google Ads fails has nothing to do with the campaign. It's the landing page. Traffic arrives ready to act and lands on a generic homepage, or a page that talks about the company instead of the buyer's problem. The click is paid for; the conversion is lost.

Every tier-one ad group should point to a dedicated landing page that matches the search, names the problem, proves the outcome, and asks for one clear action. Message match between keyword, ad, and page is the difference between a 2% and a 6% conversion rate on the same traffic. The maths behind that gap is brutal and most teams ignore it — see the conversion rate maths B2B marketers ignore .

B2B Google Ads setup checklist
  • Structure campaigns by intent tier, not by product line.
  • Start with phrase and exact match; earn broad match later.
  • Build and maintain an aggressive negative keyword list from day one.
  • Feed offline conversions from your CRM so bidding optimises for pipeline.
  • Send every ad group to a message-matched landing page, never the homepage.
  • Defend your brand terms with a small always-on campaign.

Budget and the volume ceiling

B2B search has a hard ceiling. There are only so many people searching your tier-one terms each month, and once you own that traffic, pouring in more budget just inflates your cost per click without adding qualified leads. When you hit that ceiling, the answer isn't more search budget — it's a different channel.

This is where search and paid social complement each other. Search captures the small slice of buyers actively looking; LinkedIn creates demand among the much larger group who aren't searching yet. Running both is how you grow past the search ceiling, a point we make in LinkedIn ads strategy for B2B . Set your overall number using the model in our budget guide rather than a flat percentage of revenue.

Measuring what matters

Google's default reporting will tell you about clicks, impressions, conversions, and cost per conversion. None of those tells you whether the campaign made money. The metrics that matter in B2B are cost per qualified lead, cost per opportunity, pipeline generated, and ultimately customer acquisition cost against lifetime value.

Because the lag between click and revenue is long, you have to measure on a rolling cohort basis — what did the leads from March turn into by June? A campaign that looks expensive on a 30-day conversion view often looks excellent once you let the pipeline mature. Judge it on the right timeline or you'll kill campaigns that were working.

When to bring in help

Google Ads rewards consistent, expert attention — weekly search-term review, ongoing negative-keyword work, landing-page testing, and CRM-connected bidding. Run it half-heartedly and the algorithm fills the gaps with whatever's cheapest, which is rarely your buyer. If you don't have the hands to run it properly, that's the case for senior management rather than a junior or an autopilot agency.

We run Google Ads for B2B clients as senior partners doing the work directly, not handing it to an account executive. If you want a programme built to produce pipeline rather than activity, see our Google Ads service or book a discovery call .
