Google Ads agency in Melbourne: how to choose one, and when not to

What a Google Ads agency in Melbourne actually does

A Google Ads agency runs the auction on your behalf: what you bid on, what you say, where people land, and what counts as a win. That is the whole job. Everything else on the pitch deck is decoration.

In practice the work splits into four things. Account structure, so the budget goes where the intent is. Ad copy and assets, tested rather than guessed. Landing pages, because the click is only half the transaction. And measurement, so you can tell which enquiries were worth paying for.

Melbourne changes the competitive picture more than it changes the work. Clicks in a dense metro market cost more, competitors bid harder, and the margin for a sloppy account is thinner. Google's own explainer covers how the auction works; what it does not tell you is that in a market this crowded, the account with the tighter intent beats the account with the bigger budget more often than anyone selling budget would like to admit.

What Google Ads management costs in Melbourne

Two numbers, and people constantly confuse them: the ad spend that goes to Google, and the management fee that goes to the agency. Melbourne agencies typically charge either a percentage of spend (commonly 10–20%), a flat monthly retainer, or a hybrid. None of these is inherently honest or dishonest, but they create different incentives, and you should know which one you are buying.

• Percentage of spend. Simple, scales with the account, and quietly rewards the agency for spending more of your money. Fine, as long as they are willing to tell you to spend less.
• Flat retainer. Predictable. The risk is the opposite: a small account gets the attention its fee justifies, which may not be much.
• Hybrid. A base fee plus a performance component. Only works if the performance metric is a real business outcome and not a proxy anyone can inflate.

The question worth asking is not "what is your fee". It is "what happens to your fee if you tell me to cut spend in half". The answer tells you everything about whose side the advice is on.

Five questions to ask before you sign

Every agency in Melbourne will show you a dashboard with the numbers going up. These five questions are harder to fake.

1. 1"Who owns the account?" You should. If the agency runs your campaigns inside their own manager account and you cannot take it with you, you are renting your own data. Walk.
2. 2"Show me the search terms report, not the keyword list." Keywords are what you bid on. Search terms are what people actually typed. The gap between them is where the money leaks, and an agency that lives in that report is an agency that is paying attention.
3. 3"What will you tell me not to do?" If they have never talked a client out of spending, they are order-takers.
4. 4"How will we know a lead was any good?" If the answer stops at "form submissions", the reporting stops before the part that matters.
5. 5"What happens in the first 30 days?" The honest answer usually involves fixing tracking and cleaning out waste, not launching six new campaigns.

On that second point, the search terms report is where our strongest opinion lives. Search campaigns should be built around intent, not vanity keyword lists. One keyword can look excellent right up until the search terms reveal it is catching three completely different kinds of buyer. Splitting the commercial searches from the research searches makes the budget easier to control and the ad copy easier to write, and it usually costs nothing but an afternoon.

It also feeds Quality Score, which Google calculates from expected click-through rate, ad relevance and landing page experience. Tighter intent means more relevant ads, which means you pay less for the same position. The lazy version of this job is expensive in a way that never shows up as a line item.

When not to hire a Google Ads agency at all

Here is the part the pitch deck leaves out. Sometimes the right answer is to not spend the money yet.

• Your tracking is broken. If conversions are not firing properly, nobody, agency or not, can tell a good campaign from a bad one. You will be paying someone to have opinions about noise.
• Your landing page cannot explain the offer. Traffic exposes a weak page faster than it fixes one. More clicks into a page that does not convert is just a faster way to spend money.
• Nobody follows up the leads. Cheaper leads will not fix a revenue problem caused by nobody calling anyone back.
• Your margin cannot survive Melbourne click prices. Some businesses genuinely cannot make the numbers work in a metro auction. A good agency runs that math with you before taking the retainer, not after.

If two or more of those are true, spend the first month on tracking and analytics instead. It is cheaper, it lands faster, and it makes every dollar you spend afterwards measurable. We would rather start you smaller and be able to prove it worked.

What good looks like in the first 90 days

Month one is unglamorous: fix measurement, cut the obvious waste, restructure around intent, get one clean landing page live. Month two is where testing starts, ad variants, offers, audiences. Month three is where you should be able to say, with a straight face, which searches make you money and which ones only make you busy.

If by day 90 the reporting still cannot tell you which enquiries were worth paying for, the campaign is not the problem. The measurement is, and you should be asking why nobody fixed it in month one.

That is how our Google Ads management runs, and it is why we do the service business version differently from the e-commerce version, a plumber and a store are not playing the same game, whatever the platform says.
