B2B services advertising has an awkward shape: low search volume, expensive clicks, long sales cycles, and a majority of searchers who are researching rather than buying. Tactics written for e-commerce actively mislead here — you can't optimise on last-click ROAS when the deal closes ninety days later.
This is what works when you're selling a considered service to a small number of buyers.
Structure the account around intent, not services
The instinct is one campaign per service. Better is grouping by how ready to buy the searcher is, because that's what should drive bids and budget.
Buying intent — hire, agency, company, services, consultant, pricing, cost, for hire. These convert. Bid aggressively.
Comparison intent — best, vs, alternatives, top, reviews. Real prospects, earlier in the process. Bid moderately, send to comparison content rather than a hard sales page.
Research intent — how to, what is, tutorial, guide, example. Mostly people doing it themselves. Usually shouldn't be in your search campaigns at all. Win these with content, not paid clicks.
Splitting this way lets you spend where money is and starve where it isn't. Mixed into one campaign, your research traffic quietly consumes the budget your buying traffic needed.
Match types
Phrase and exact do the work. Broad match hands targeting to Google's inference, which needs conversion volume to work well — volume a small B2B account doesn't have. On a limited budget, broad match finds you expensive irrelevance.
If you use broad match, pair it with a strict negative list and check search terms weekly. Not monthly. Weekly.
A workable starting structure:
- Exact match on your handful of proven buying-intent terms, higher bids
- Phrase match on close variants, moderate bids
- Broad match only once you have conversion data worth optimising on, and only in its own campaign so it can't cannibalise budget
Negative keywords
The highest-return work in a B2B account, and it never finishes.
A starting list for technical services:
free, cheap, tutorial, course, learn, training, certification,
jobs, salary, career, hiring, intern, internship, resume, cv,
github, open source, download, template, example, sample, pdf,
diy, how to, what is, meaning, definition, wikipedia,
student, university, thesis, project ideasAdd your own ongoing exclusions: countries you don't serve, technologies you don't work in, and — importantly — job-seeker phrasing, because "developer" attracts people wanting to be one.
Then work the search terms report weekly. This is where the real list comes from. Every account develops its own irrelevant queries, and no generic list predicts them. An hour a week for the first two months, permanently thereafter at lower intensity.
Bidding on low volume
The core difficulty: smart bidding strategies need conversion data, and B2B services accounts generate few conversions.
Start with manual CPC or maximise clicks with a bid cap. Gather data first.
Count the right conversion. If you optimise on form fills, you'll get form fills — including from students and job seekers who slipped past your negatives. Where possible, feed qualified leads back as your conversion event via offline conversion import keyed on gclid. Then the algorithm optimises toward buyers.
Only move to Target CPA once you have enough conversions to be meaningful — and if you're getting a handful a month, you may never get there. Manual bidding on a tightly-targeted account is entirely respectable.
Set a realistic target. Work backwards: if you close one in five qualified leads, and a client is worth a certain amount, your acceptable cost per qualified lead follows from that arithmetic. Guessing a CPA target is how accounts get throttled to no volume or bled dry.
Ads and landing pages
Write for disqualification as much as qualification. A B2B ad that mentions a starting price or a minimum engagement size costs you clicks — from people who were never going to buy. On expensive clicks that's a saving, not a loss.
Use the ad copy to set expectations. "Custom-built, from scope to launch" attracts a different clicker than "affordable websites." You want the former.
Ad extensions are free real estate. Sitelinks to your specific service pages, callouts for genuine differentiators, structured snippets for the services you offer. They increase your share of the results page at no additional cost.
Landing page must match the ad. Ad says WhatsApp AI agents, page headline says WhatsApp AI agents. Sending everything to your homepage wastes a meaningful share of paid traffic — and homepage traffic converts worse on every account I've seen.
What to expect
Some honest numbers-shaped guidance without inventing figures:
Volume will be low. A niche B2B service might see a few hundred relevant searches a month in your target markets. That's not a problem to solve by broadening — broadening finds you irrelevant traffic. It's the shape of the market.
Clicks will be expensive relative to consumer categories, because the buyers are valuable and competitors know it.
Attribution will be unsatisfying. Long cycles, multiple touchpoints, and offline decision-making mean last-click understates paid search. Offline conversion import helps; it doesn't fully solve it.
Give it time. Judging a B2B search campaign on two weeks is meaningless. Think in quarters, and judge on qualified pipeline, not lead count.
A sensible first month
- Week 1 — build tight exact and phrase campaigns on buying-intent terms only. Full negative list from day one. Manual bidding. Dedicated landing pages.
- Week 2 — search terms report. Add negatives. Pause anything obviously wrong.
- Week 3 — same again. Start noting which terms produce qualified leads, not just leads.
- Week 4 — set up offline conversion import so qualification feeds back. Only now consider automated bidding.
Resist adding keywords, campaigns, and match types early. A small, tight, well-negated account outperforms a sprawling one at this budget level, consistently.
