Will Google Ads work for your business? Three tests

Say you run a small removals business in Adelaide. You have set aside AUD 2,000 to try Google Ads, the account is half built, and the only thing left is to switch it on. Before you do, spend twenty minutes checking whether that money has a realistic chance of coming back.

Google Ads does not create customers. It puts your business in front of people already searching for what you sell. That is a narrower job than many owners expect, and it explains nearly every account that succeeds or fails. If demand for your service already exists in search, you can buy your way to the front of it. If it does not, no budget or bidding strategy will manufacture it.

So the first AUD 2,000 should wait until your business passes three tests. Each one below is something you can check yourself this week.

What you are buying

Intent. Every other advertising channel interrupts someone doing something else and hopes the message lands. Search works the other way round. Someone types “emergency electrician Parramatta” at 7pm, and the only question left is which business appears first. The wanting has already happened.

This is why Google Ads feels expensive per click and cheap per customer when it works. You are paying a premium to skip the persuasion stage entirely, and that premium is usually worth it.

It is also why it fails so predictably for new products nobody is looking for yet. You cannot bid on a search that nobody types, and you cannot teach people to want something through a text ad they will never see.

Condition one: people are already searching for what you sell

Open Google and type what a customer would type. If the results are full of competitors paying for ads, that is your proof of demand. Advertisers do not keep paying for searches that produce nothing.

The reverse is equally informative. If nobody is bidding on your category, you are usually looking at a market where buyers do not search, not a bargain nobody noticed.

Then put numbers on it. Google’s Keyword Planner sits inside every Google Ads account and shows estimated monthly searches for a keyword, along with the average cost for an ad to show on those searches. Look up the ten or so phrases your customers would use and note both figures.

Check the wording as well as the volume. Customers rarely search in your industry’s language, so if you sell “integrated facilities management” and they type “office cleaning Melbourne”, the demand is there but you will not find it looking for your own words.

For Australian service businesses this test usually passes easily. Trades, legal, dental, accounting, removals, real estate and home services all have people typing suburb-level searches every day, and a business that opened last month competes on the same terms as one that has traded for twenty years. For a brand-new product category it tends to fail, and the honest answer is that social media marketing creates that demand first and search captures it later.

Condition two: your numbers survive the click maths

This is where you stop guessing and calculate. The maths is simple, and it is the most useful thing you can do before spending anything.

Start with the price of a click. Keyword Planner gives a range for each keyword, and once campaigns are live the top of page bid estimate shows roughly what it takes to appear above the organic results. Prices vary a lot by industry and suburb, with legal, insurance and finance terms sitting well above trades and home services. The table runs that AUD 2,000 through at an illustrative AUD 4 a click.

Step	Illustrative figure	How it is worked out
Budget	AUD 2,000	Your first test spend
Average cost per click	AUD 4	Assumed, check your own keywords
Clicks	500	2,000 ÷ 4
Landing page conversion rate	3%	Assumed
Enquiries	15	500 × 3%
Cost per enquiry	About AUD 133	2,000 ÷ 15
Close rate	25% (one in four)	Assumed
Customers	About 3.75	15 × 25%
Cost per customer	About AUD 533	2,000 ÷ 3.75
Gross profit needed per customer to break even	More than AUD 533	Profit, not revenue

Now swap in your own figures. If your average customer is worth AUD 300 in gross profit, that example loses around AUD 233 on every customer it wins, and no amount of optimisation closes a gap that wide. If your average customer is worth AUD 5,000, you have enormous room to be imperfect and still make money.

This is also why the same industry can be profitable for one business and ruinous for another. The bidding is identical. The margins are not.

One thing the table cannot show is time. Enquiries can arrive on day one, but an account usually needs a month or two of conversion data before bidding settles. Judge the first AUD 2,000 on the trend across the whole period, not on week two.

Condition three: someone answers the phone

The unglamorous condition, and the one that sinks more accounts than bad keywords.

Search intent is immediate. Someone looking for an emergency plumber at 7pm is calling three businesses and hiring whoever picks up. An enquiry that sits in an inbox until Tuesday morning has already been spent.

Before your ads go live, be honest about what happens after the click. Who answers, how fast, and what they say. A business that responds within five minutes will usually beat a better-funded competitor that responds the next day, on the same keywords.

Where Google Ads does not work

It is a poor fit in four situations, and recognising yours early saves a lot of money.

Nobody searches for your category yet, because the product is new. Your margins cannot absorb Australian click prices. Your website has no page matching what people search for, which is a web design problem before it is an advertising one.

The fourth is budget. Below about AUD 1,000 a month in most Australian markets, an account never gathers enough data to improve, so you pay beginner prices indefinitely. In our view, a local service business is better placed somewhere between AUD 1,500 and AUD 3,000 a month, which is why AUD 2,000 works as a first test.

None of these are fixed by a better agency. They are fixed by changing the underlying business condition, or by choosing a different channel. Where demand exists but clicks are unaffordable, search engine optimisation reaches the same people more slowly at no cost per click.

What to have ready before you start

If the three tests pass, the result now depends on your tracking, your website and your account discipline. Plenty of owners run their own account competently; the usual failure is maintenance, because accounts drift within weeks without someone reviewing search terms. If you would rather hand that over, here is what PPC management costs and what the fee should cover. Either way, have these ready first, in this order.

1. Conversion tracking that records real enquiries. Page views do not count. Google’s conversion measurement lets you record the calls, forms and bookings that matter, and without it you are buying traffic blind and every later decision is guesswork.
2. A landing page that matches the search. Sending every keyword to your homepage is the most common reason accounts underperform, and it also raises what you pay, because relevance is part of how Google prices your clicks.
3. A tight, deliberate keyword list. More keywords is not more reach, it is the same budget spread thinner, and the right number is smaller than most people expect.
4. A plan for the phone and inbox. Decide who answers enquiries during the hours your ads run, and how quickly.
5. Your break-even number. The cost per customer you can afford, worked out from the table above with your own margin, so you know within a month or two whether the test is on track.
