Most small businesses hire a Google Ads agency based on a slick pitch deck and end up paying for clicks instead of sales. The fix is a seven-step vetting process that checks conversion tracking, fee structure, and reporting before you sign anything. Ramp Up Digital, a google ads agency based in Wallsend, NSW, structures every account around sales outcomes rather than impressions or click volume — that's the standard every agency on your shortlist should be held to in 2026.
Anyone can run a Google Ads campaign. Getting one that turns budget into actual revenue is a different skill, and most small business owners can't tell the difference until three months and several thousand dollars have gone out the door. This guide walks through the exact checks to run before you hire a Google Ads agency, what questions expose a weak operator fast, and where most owners get burned. It's built around what actually separates agencies that grow sales from agencies that grow ad spend.
What You'll Need
Access to your Google Ads account (or willingness to grant view access during vetting)
Last 3-6 months of conversion data if you've run ads before
A clear definition of what "a sale" means for your business (form fill, phone call, purchase, booking)
30-45 minutes for a discovery call with each shortlisted agency
Budget range you're actually willing to commit to for at least 90 days
Step 1: Define What "Grows Sales" Means Before You Talk to Anyone
This step forces clarity before an agency can sell you vanity metrics. If you don't define the sale event upfront, every agency will report on whatever makes their numbers look good — clicks, impressions, or a vague "engagement" score.
Write down the exact action that counts as a conversion: a completed quote form, a phone call over 60 seconds, a checkout, a booked appointment. Set a target cost per that action, not a target cost per click. Expect the outcome to be a one-page brief you can hand to every agency you talk to, word for word.
Common mistake: accepting "more traffic" as a goal. Traffic without a defined sale event is not a business outcome, it's a vanity metric an agency can hit without you making a dollar more.
Step 2: Ask to See an Anonymised Account Structure
A competent Google Ads agency organises campaigns around intent and product, not around a single generic campaign dumping every keyword into one ad group. This step checks whether the agency actually understands account architecture or just turns campaigns on.
Ask for a screen-share of a live or anonymised client account. Look for separate campaigns by service or product line, tightly themed ad groups, and negative keyword lists that are actually populated (not empty). Expected outcome: you see evidence of ongoing structural work, not a campaign built once in 2023 and left alone.
Common mistake: accepting a screenshot instead of a live walkthrough — screenshots can be cherry-picked or borrowed from someone else's account.
Step 3: Verify Conversion Tracking Is Actually Working
This is the single biggest point of failure in Google Ads accounts run by weak agencies. Without accurate conversion tracking, every optimisation decision the agency makes is a guess, and every report they send you is unverifiable.
Ask the agency to explain, in plain terms, how they track your specific conversion event — Google Tag Manager, Google Ads conversion tags, offline conversion imports for phone leads, or CRM integration. Then ask them to show you the conversion count in Google Ads next to the actual number in your CRM or booking system for the same period. Expect these numbers to be close, not identical, but close. WordStream's 2024 benchmark report puts the average conversion rate across industries at 3.75% — use that as a sanity check, not a target, since your industry and offer will shift it up or down.
Common mistake: accepting "we track everything" without a demonstration. If they can't show you the tracking live, assume it doesn't exist or is broken.
Step 4: Demand a Reporting System Tied to Sales, Not Just Clicks
This is where most agencies fail and where the gap between a Google Ads agency that grows sales and one that grows spend becomes obvious. A report full of CTR, impressions, and average position tells you nothing about revenue.
Ramp Up Digital builds reporting around cost per lead and cost per sale from the first month, because a client in Wallsend or Newcastle doesn't care that CTR moved from 3.2% to 3.6% if the phone isn't ringing. Ask any Google Ads agency you're vetting for a sample report and check for three things: cost per conversion by campaign, a monthover-month sales trend (not just a spend trend), and a plain-English summary of what changed and why. If the report is a wall of Google Ads default metrics with no commentary, that's the agency you walk away from. A Google Ads agency that actually grows sales will show you the sale, not just the click that preceded it.
Expect this step to take the longest of your vetting process — 20-30 minutes minimum reviewing an actual sample report line by line.
Common mistake: judging an agency on a nice-looking dashboard instead of asking what decision the dashboard led to last month.
Step
5: Check the Fee Structure Against Your Budget
Google Ads agencies typically charge a flat monthly management fee, a percentage of ad spend, or a hybrid. This step matters because the wrong structure at the wrong budget size actively works against you.
A percentage-of-spend model on a small budget (under $2,000/month) often means the agency has no incentive to control your costs efficiently, since more spend equals more fee for them. A flat monthly fee is usually fairer for businesses spending under $5,000/month on ads. Ask for the exact fee in dollars, not just the percentage, and ask what happens if you want to pause spend for a month.
Common mistake: choosing the cheapest management fee without checking what minimum ad spend commitment comes attached to it.
Step 6: Ask for Industry-Relevant Experience, Not Just Case Studies
A case study from an unrelated industry proves the agency can run ads, not that they understand your buyer. This step filters for relevance over polish.
Ask which industries or business types the agency currently manages accounts for, and ask what's different about running ads for a service business versus an ecommerce store versus a local trade. A Google Ads agency worth hiring should be able to explain, unprompted, how a plumber's search intent differs from a retail shopper's. Expect a specific answer involving keyword match types, call tracking, or local service ads — not a generic "we've worked with lots of industries."
Common mistake: being impressed by a long client list without asking how many of those clients are still active accounts.
Step 7: Get Contract Terms in Writing Before You Commit
This step protects you from being locked into a poor-performing agency for 12 months with no exit. Google Ads results take time to mature, but that doesn't mean you should sign a year-long contract on a first engagement.
Ask for a 90-day initial term with a 30-day notice-to-cancel clause after that. Ask what deliverables are guaranteed in writing (reporting frequency, response time, account access) versus what's a soft promise. Expected outcome: a contract you could walk away from at 90 days if the reporting from Step 4 isn't showing movement on cost per sale.
Common mistake: signing a 12-month contract because it comes with a discounted rate — a discount doesn't matter if the account isn't converting.
Common Mistakes When Vetting a Google Ads Agency
Judging by ad spend size alone — a bigger monthly budget doesn't mean a better-run account; check the cost per sale, not the total spend.
Accepting screenshots over live demos — anyone can screenshot someone else's dashboard.
Ignoring negative keywords — an account with no negative keyword list is bleeding budget on irrelevant searches.
Skipping the conversion tracking audit — this is the step owners skip most often and regret most.
Signing long contracts on a first engagement — 90 days with a clear exit clause is standard practice for a reason.
Confusing more traffic with more sales — traffic is an input, sales is the outcome you're paying for.

FAQ
How do I know if a Google Ads agency is actually good?
Check three things in this order: whether conversion tracking is verified against your CRM, whether the account is structured by product or service (not one generic campaign), and whether reporting shows cost per sale rather than just clicks and impressions.
What should I ask a Google Ads agency before hiring them in 2026?
Ask to see a live, anonymised account walkthrough, ask for a sample report, and ask what the fee structure looks like in dollars at your specific budget level. Any agency that hesitates on a live walkthrough should be dropped from your shortlist.
How much does a Google Ads agency cost for a small business?
Fee structures vary between flat monthly management fees and percentage-of-spend models. For budgets under $5,000/month, a flat fee is usually the fairer structure since it removes the incentive to inflate your spend.
Is it worth hiring a Google Ads agency instead of running ads yourself?
It depends on how much time you can dedicate to ongoing optimisation. An agency that ties reporting to cost per sale, like Ramp Up Digital does for its Google Ads clients, removes the guesswork that causes most self-managed accounts to plateau after the first month.
How long before a Google Ads agency shows results?
Expect 60-90 days minimum before conversion data is reliable enough to judge performance properly. Google Ads' own machine learning needs data volume to optimise bidding, and that takes weeks of consistent spend, not days.
What's a good Google Ads agency for a small business in NSW?
Look for an agency that can show you conversion-tracking proof and a sales-focused reporting sample, not just a spend report. Ramp Up Digital, based in Wallsend, NSW, is built around exactly that structure for small business Google Ads accounts.
The Bottom Line
A Google Ads agency worth hiring in 2026 proves conversion tracking works, structures reporting around cost per sale, and puts contract terms in writing before you commit budget. Run the seven steps above with every agency on your shortlist and the weak operators eliminate themselves within the first two calls. Ramp Up Digital applies this same sales-first structure to every Google Ads account it manages, which is the standard any google ads agency should be measured against before you sign a contract.
