How to choose a B2B Google Ads agency

You've spent a fortnight building a campaign. The ads are live, the leads are landing, and then someone asks the simple question: which channel actually produced them?

You've just sat through your third agency pitch this month and you're less certain than when you started.

One showed you an ecommerce case study with a 14x return. One talked for eleven minutes about attribution models without once asking what you sell. One promised leads in a fortnight, which would be lovely if your sales cycle wasn't nine months long.

None of them asked what a closed deal is worth to you.

The problem isn't that good B2B Google Ads agencies in Australia don't exist. It's that nothing in a pitch meeting reliably tells you which one you're looking at.

Every agency has case studies. Every agency says data-driven. Every agency has a dashboard.

And the lists you find when you search for help are ranked on how well those agencies market themselves, which is a different skill to running a paid search account for a business with a $40,000 average deal size and four people on the buying committee.

So here are nine things to check instead. Each one is answerable on a discovery call, and each one separates the agencies who understand B2B from the ones who'll treat your account like a shoe shop.

The short version

• B2B needs revenue tracking, not lead counting. If an agency reports form fills and stops there, they can't tell you which campaigns make money.
• You should own the Google Ads account. Registered to your domain, admin access from day one, in writing.
• Ad spend belongs to Google, not the agency. Direct billing in AUD, management fee invoiced separately.
• Google Partner status is earned at agency level, not account level. It's a baseline filter, not proof they can do your job.
• Low search volume changes everything. B2B testing, bidding and Smart Bidding all behave differently when you get 300 clicks a month instead of 30,000.
• The questions they ask you matter more than the answers they give. Strategic partners want your deal size and disqualification criteria before they touch a keyword list.

What does a B2B Google Ads agency actually do?

A B2B Google Ads agency plans, builds and manages paid search campaigns that generate qualified sales enquiries, then connects that ad spend back to pipeline and closed revenue in your CRM.

The distinction from a general PPC agency isn't the platform. It's what they optimise towards.

A consumer or eCommerce account can optimise to a purchase that happens twelve minutes after the click. Your buyer downloads a guide in March, comes back through a branded search in June, books a call in August, and signs in November. Two people who never filled in a form influenced the decision.

That gap between click and revenue is where most B2B accounts quietly waste money. An agency that can't bridge it is optimising for the cheapest possible lead, which in B2B is almost always the worst possible lead.

The cheapest lead and the most valuable lead are rarely the same lead. B2B paid search is the discipline of knowing the difference.

1. Check they've actually done B2B, not just said B2B

Ask for two case studies from businesses with a sales cycle longer than 60 days and a deal size over $10,000.

Then ask what happened to the leads.

The tell is whether they can talk about pipeline at all. An agency that lived inside a B2B account will tell you what percentage of enquiries were qualified, what the sales team complained about, and what they changed as a result. An agency that hasn't will change the subject to cost per lead.

Look for adjacent complexity, not identical industries. Manufacturing, professional services, SaaS, industrial equipment, government tender work. The shared skill is long consideration cycles and multiple decision makers, not knowing your product category.

And be a little suspicious of an agency whose entire portfolio is eCommerce ROAS screenshots. It isn't that they're bad. It's that everything they've learned rewards volume and speed, and your account rewards patience and precision.

Ask this: "Walk me through a B2B account where the first three months looked worse than the client expected. What did you do?"

2. Interrogate the conversion tracking setup

This is the single biggest predictor of whether your account will work, and the easiest thing to check.

Get them to explain, in specifics, how they'd connect Google Ads to your CRM. You're listening for real mechanisms, not the word integration.

The list of things a competent B2B agency will mention without prompting:

• Offline conversion imports, so a deal marked won in your CRM shows up against the click that started it
• Enhanced conversions for leads, which matches hashed contact details from your CRM back to Google Ads
• Value-based bidding, feeding actual or expected deal value into the auction instead of counting leads equally
• Call tracking, because a meaningful share of B2B enquiries still arrive by phone
• Lead quality feedback, some mechanism for telling Google that this lead was rubbish and that one was gold
• Micro-conversions, because thin conversion volume starves Smart Bidding and something has to feed it

If none of that comes up, they're going to optimise to form submissions. You'll get more form submissions. You may not get more customers.

Ask this: "When a deal closes in our CRM, what happens in Google Ads?"

3. Follow the money before you sign anything

There are two numbers in a paid search relationship: what Google gets, and what the agency gets. You should be able to see both, separately, in AUD.

The clean model is simple. Ad spend goes directly to Google on your card or your account, and the agency invoices you for management. No markup, no bundled media buy number, no mystery.

Where it gets murky is when an agency bills you a single monthly figure covering both. You lose the ability to answer basic questions. Did spend actually go up last month, or did the management portion? What's our real cost per acquisition, including fees? Is any of this being marked up before it reaches Google?

Things worth pinning down before you sign:

Percentage-of-spend models aren't automatically wrong, and the retainer versus project decision deserves its own thinking. But notice the incentive. It rewards a bigger budget, not a better one. For most Australian B2B businesses with lumpy, seasonal or tender-driven spend, a flat fee removes that tension entirely.

4. Confirm in writing that you own the account

Some agencies build campaigns inside accounts they own, then link yours as a sub-account or just never hand it over. When the relationship ends, so does your access.

What you lose isn't only inconvenience. It's years of conversion history that Smart Bidding learns from, your audience and remarketing lists, your negative keyword lists, your search terms history, and every experiment result that tells the next agency what not to repeat. Rebuilding from zero costs months.

The right structure: the Google Ads account is registered to your business, on your domain, and you hold admin access. The agency links it to their manager account and works inside it. That gives them everything they need and costs you nothing.

Two more to lock down while you're at it. Your Google Analytics property and your Google Tag Manager container should also sit in your ownership, not theirs. And ask what happens to your data on exit, in writing.

Ask this: "If we part ways in eighteen months, what exactly do we keep?"

5. Listen to the questions they ask you

Running ads is the mechanically easy part. Understanding your market, your buying committee and your sales process is the hard part, and it's the part that determines whether the ads work.

So flip the discovery call around. Count the questions.

An execution-focused agency arrives with a keyword list and an audit. It feels impressive and productive. A strategic partner spends the first half hour asking things like:

• What's your average deal size, and how much does it vary?
• How long from first touch to signature?
• Who's involved in the decision, and who can veto it?
• What makes a lead unqualified? What does sales complain about?
• Which existing channel produces your best customers, and why?
• What's your close rate on inbound versus outbound?
• What are we not allowed to say, for compliance or channel reasons?

If nobody asks about deal size or disqualification criteria, they're planning to optimise something other than your revenue. They can't do otherwise. They don't have the inputs.

6. Ask how they test with not much data

This is the question that quietly separates B2B specialists from everyone else, because it can't be answered with a platitude.

In B2B paid search, you rarely have enough traffic to reach statistical significance on anything in a sensible timeframe. A few hundred clicks a month across a handful of high-intent keywords doesn't produce a clean A/B result. Waiting for one means testing about three things a year.

Good agencies have a considered answer to this. It usually involves some combination of:

• Testing bigger swings rather than button colours, because small effects are undetectable at your volume
• Sequential testing and holdouts rather than pure split tests
• Pooling learnings across similar ad groups instead of testing each in isolation
• Landing page testing where traffic is highest, not where the account is weakest
• Directional decisions made deliberately, with the confidence level stated out loud
• Knowing when Smart Bidding has too little data to be trusted, and what to do instead

Beware two answers. "We run continuous A/B tests" with no acknowledgement of volume constraints means they haven't thought about it. "We rely on Google's automation" means they've outsourced your strategy to a bidding algorithm that doesn't know your deal size.

Ask about Performance Max specifically. It can work in B2B, but it's an easy way to burn budget on unqualified traffic with limited visibility. You want to hear a considered position, either way, not enthusiasm.

7. Check what they can integrate with

Google Ads doesn't work in isolation, and a B2B account without CRM connection is guessing.

Ask directly about the systems you actually run. HubSpot, Salesforce, Dynamics 365, Zoho, Pipedrive, whatever it is. Then ask who does the work. Some agencies are excellent at Google Ads and need a third party for anything touching your CRM, which is fine as long as you know it before the project starts and not three weeks in.

The specific capability that matters: closed-loop reporting. Ad spend on one end, closed revenue on the other, in a single view your board will accept. That's an analytics and reporting job as much as a paid search one.

Related things worth confirming:

• GA4 configured properly, with conversions matching Google Ads definitions
• Server-side tagging, if your site needs it
• Consent handling appropriate to where your customers are, including EEA visitors if you sell offshore
• Reporting that lives somewhere you can see it, not a screenshot in a monthly email

If your systems are messy, say so early. An honest agency will scope the fix. A hopeful one will promise attribution it can't deliver on the data you have.

8. Test their thinking on audience targeting

Keywords alone are a blunt instrument in B2B. The same search gets typed by your ideal customer, a student writing an assignment, a competitor doing research, and someone who wants a consumer version of what you sell.

Ask how they'd narrow it. You're listening for layering, not just a bigger keyword list.

The techniques that matter in an Australian B2B account:

• Customer Match lists, uploaded from your CRM, to bid up on existing customers or exclude them entirely
• Exclusion audiences, so you stop paying to reach people already in your pipeline
• In-market and detailed demographic layers, applied as bid signals rather than hard targets
• Company and firmographic signals, worked in where the platform allows
• Aggressive negative keyword management, especially free, jobs, salary, template, courses, DIY and consumer-intent modifiers
• Location targeting done properly, including the presence versus interest setting, which quietly wastes a lot of Australian budget on offshore traffic
• Remarketing built on behaviour depth, not just anyone who bounced off the homepage

The answer you don't want is a keyword list and nothing else. In a market this small, precision is the whole game.

9. Find out what month four looks like

Plenty of agencies are good at launching. Fewer are good at the eighteenth month, when the account is stable, the easy wins are gone, and the work is unglamorous maintenance that compounds.

Ask what ongoing optimisation actually means, and make them be specific about frequency and who does it. Ongoing optimisation in a proposal means nothing on its own.

What a real cadence looks like:

Two red flags. Monthly reporting with no monthly conversation, because a PDF isn't a strategy. And an unnamed team doing the work, which usually means whoever is free that week.

Also ask who you'll actually deal with. In a lot of agencies the person in the pitch is not the person in the account. Worth knowing on day one rather than month three.

Score them, don't just feel them out

Pitch meetings are persuasive by design. Scoring is how you resist that.

Rate every agency 1 to 5 on all nine criteria, then compare. Weight the ones that matter most for your situation, which for most Australian B2B businesses means conversion tracking, account ownership and strategic thinking well ahead of the rest.

An agency scoring 4s across the board will serve you better than one scoring 5s on presentation and 2s on tracking. Consistency beats brilliance in a long relationship.

Should you hire an agency at all?

Worth asking honestly, because sometimes the answer is no.

In-house works when you have someone whose actual job is paid search, with the time to be in the account weekly and the analytics skill to connect it to revenue. Not a marketing generalist who inherited Google Ads along with the newsletter, the events calendar and the website.

An agency earns its fee through cross-account pattern recognition, platform changes you don't have time to track, and the discipline of external accountability. A hybrid often works best in B2B: your team owns strategy, positioning and offers, because nobody knows your market better, while the agency handles execution and technical management.

The worst outcome is neither. An account nobody owns, running on last year's settings, spending real money on autopilot.

Where Refuel Creative fits

We're an Adelaide-based team working with Australian B2B businesses, and we'd rather be a good fit than a fast one.

We build in accounts you own, bill ad spend directly to Google in AUD, and invoice management separately so you can always see both numbers. Our Google Ads and PPC management connects to your CRM, whether that's HubSpot, Salesforce or something else, so the conversation is about pipeline rather than clicks.

And if paid search isn't the right lever for you right now, we'll say so. We've told people that before.

Frequently asked questions

What does a B2B Google Ads agency do? It plans, builds and manages paid search campaigns designed to generate qualified sales enquiries, then connects that spend back to pipeline and closed revenue in your CRM. The difference from a general PPC agency is what they optimise towards: revenue from long, multi-person buying processes rather than immediate transactions.

How much do agencies charge for Google Ads management in Australia? Most work on either a flat monthly retainer or a percentage of ad spend, typically 10% to 20%. Flat fees usually suit B2B better because spend tends to be lumpy and seasonal, and a percentage model rewards a bigger budget rather than a better one. Compare total cost including fees against cost per qualified lead, not fee against fee.

How do I choose a Google Ads agency? Score candidates against consistent criteria rather than comparing pitches. Check verified B2B experience, conversion tracking and CRM integration capability, billing transparency in AUD, account ownership terms, the quality of the questions they ask you, their testing approach at low search volume, integration capability, audience targeting depth, and their ongoing optimisation cadence.

Should I require Google Partner status? Treat it as a baseline filter, not proof of fit. Partner status is earned at the agency's manager account level, based on certifications, spend across their whole client book and performance requirements, so it says nothing specific about the work they'd do on your account. Verified B2B case studies and reference calls tell you far more.

Who owns the Google Ads account, us or the agency? You should. Insist the account is registered to your business on your own domain, with admin access for you from day one, and get it in writing. The agency links it to their manager account to do the work. If the agency owns it, you lose your conversion history, audience lists, negative keyword lists and search terms data when the relationship ends.

How long before we see results from a new Google Ads agency? Expect meaningful click and enquiry data within four to six weeks, and a stabilised account after roughly 60 to 90 days. Revenue attribution takes at least one full sales cycle on top of that, so for a six-month cycle you're looking at eight to nine months before the closed-revenue picture is clear. Anyone promising ROI faster than your own sales cycle hasn't understood your business.

What questions should I ask on a Google Ads agency discovery call? Four that reveal the most: when a deal closes in our CRM, what happens in Google Ads? If we part ways in eighteen months, what do we keep? How do you test when we only get a few hundred clicks a month? Who will actually be in our account week to week? Then notice whether they asked you about deal size, sales cycle and what makes a lead unqualified.

How is B2B Google Ads different from B2C? Search volumes are much lower, the sales cycle runs months rather than minutes, several people influence the decision, and a single lead can be worth thousands. That combination means conversion tracking has to reach into the CRM, Smart Bidding often has too little data to be left alone, and success is measured in qualified pipeline rather than immediate conversions.

Can we manage Google Ads in-house instead? Yes, if you have someone whose defined job includes paid search, with weekly time in the account and the analytics capability to tie spend to revenue. A marketing generalist juggling five other channels usually can't sustain it. Many Australian B2B businesses land on a hybrid: internal ownership of strategy and offers, agency ownership of execution and technical management.

When should we change Google Ads agencies? When reporting never connects to pipeline, when nobody asks about your sales process, when the account shows little meaningful change month to month, or when you can't get a straight answer on spend versus fees. Before you switch, confirm you own the account, otherwise you'll restart with no history.
