Is Google Ads Worth It for a Small Business in Adelaide?

The short answer

Google Ads is not a growth strategy. It is a way to buy attention from people who are already looking for what you sell, at a price set by whoever else wants that same attention. That makes it one of the most measurable channels available to a small business, and also one of the easiest to lose money on, because you pay for the click whether or not anything comes of it.

So the question is never really “does Google Ads work”. It works. The question is whether it works at a price your business can absorb, and that answer is specific to your margins, your close rate and your market. It is arithmetic, not opinion, and you can do most of it before you spend a dollar.

Work out whether the maths works for your business

Start at the end, with a job you have already won, and work backwards. There are only 4 numbers involved and you probably know 3 of them already.

1. What is an average job worth to you in gross profit? Not revenue. Profit, after materials and labour. If a job invoices at $1,800 and costs you $1,200 to deliver, the number you are working with is $600.

2. What share of enquiries do you actually win? Be honest here, and use your real close rate rather than the one you would like. If 1 in 3 enquiries turns into a job, then an enquiry is worth roughly $200 to you ($600 profit multiplied by a 33% close rate).

3. What does a click cost in your category? This is the one number you cannot guess, because it is set live by your competitors and varies enormously between industries. We quote it per account from real data rather than publishing a figure that flatters the pitch, and the Adelaide Google Ads cost guide breaks down how the fee and the spend sit alongside each other.

4. How many clicks does it take to produce 1 enquiry? A purpose-built landing page that matches the search converts far better than a homepage. On a South Australian roofing account we manage, a roof-replacement page converts at 31.13% and a gutter-replacement page at 30.00%. Those are unusually strong. Plan on something more conservative until you have your own data.

Now put it together. If clicks cost $6 and 1 in 20 becomes an enquiry, each enquiry costs you $120. Against an enquiry worth $200, you are ahead, and the channel is worth running. Change the close rate to 1 in 6 and the same enquiry is worth $100 against a $120 cost, and you are paying to lose money slowly. That single line of arithmetic settles the question faster than any agency proposal will.

When Google Ads is not worth it

This is the part most agencies skip, because every one of these is a sale they would rather not talk themselves out of. There are 4 situations where we will tell you not to advertise, and we would rather say it at the free review than 3 months into an invoice.

You do not have the margin to pay for a click. If you sell a $40 product with $12 of profit in it, and a click costs $4, you need better than 1 conversion in every 3 clicks just to break even. Almost nothing converts at that rate. Low-margin, low-ticket businesses are usually better served by organic search, repeat customers and referral than by paid clicks, and a Shopping campaign only rescues that if volume and average order value are both higher than they look.

Nobody is searching for what you sell. Google Ads captures demand, it does not create it. If your product is genuinely new, or solves a problem people do not yet know has a name, the search volume simply is not there. You will end up bidding on vague adjacent terms, paying for curious clicks and calling it a failed campaign when it was really the wrong channel. A quick look at actual search volume for your terms answers this in 10 minutes.

You cannot answer the phone. This is the most common and most expensive one. Paid search enquiries are perishable. Someone with a burst pipe who fills in a form at 9am and hears nothing by 11am has already called someone else, and you paid for that click. If you are on the tools all day with no one covering the phone, and no system for responding fast, fix that before you spend anything on ads. It is the cheapest conversion rate improvement available to you.

Your budget is under about $1,000 a month.Below that, the problem is not just reach, it is data. At $6 a click, $1,000 buys around 166 clicks a month, or about 5 a day. That is not enough for Google’s bidding to learn, not enough for search-term pruning to be based on anything but noise, and not enough for you to tell a good month from a lucky one. Add a management fee on top and the fee is a large share of total investment. If a small budget is all that is available right now, it is usually better spent on one tight campaign you run yourself, or on Google Business Profile and organic search, until there is more to work with.

What a realistic starting budget looks like

Most businesses we work with start from around $1,500 a month in ad spend. That is not a minimum we impose to protect a fee, it is the point at which an account collects enough conversions to be improved rather than guessed at. The spend goes directly to Google in an account you own, separate from any management fee, so you keep the account and its history whatever happens next.

What matters more than the number is how narrow you are willing to be with it. A budget concentrated on 1 or 2 profitable services, in the suburbs you actually want to work in, beats the same money spread thinly across everything you offer across the whole state. The temptation is always to advertise the full list. Resist it until one service is provably working, then widen.

How long before you can judge it

Give it 30 days before you read anything into the numbers and 90 days before you decide. The first month is largely about collecting conversion data: which search terms actually produce enquiries, which produce clicks and nothing else, and where the landing page loses people. Months 2 and 3 are where cost per enquiry usually improves, because by then there is enough evidence to cut waste with confidence rather than on a hunch.

Anyone promising results in week 1 is either bidding on your own brand name, which is cheap and would have found you anyway, or is about to show you a report full of impressions. On an Adelaide plumbing client who came to us after 5 agencies in 10 years, new Google-sourced enquiries went from 13 to 41 a month, and the 41 arrived in month 4. That is a normal shape for a campaign that ends up working.

If it is already running and not working

Doubt about Google Ads is often really doubt about how a specific account is being run. Before you conclude the channel is wrong for you, check 4 things. Is conversion tracking actually recording calls, form submissions and phone-link taps, or is it counting page views as conversions? Is the traffic landing on a page built for that search, or on a homepage? Is the targeting set to your real service area or to the whole state? And is the search-terms report full of terms you would never have chosen?

Those 4 faults account for most of the accounts we are asked to look at, and all of them are fixable without increasing your budget. If the tracking is broken, the account is flying blind and every performance conclusion drawn from it, good or bad, is unreliable. Fix the measurement first, then judge the channel.

Where an agency actually earns its keep

Honestly, not every business needs one. If you are advertising a single service in a couple of suburbs on a small budget, a simple campaign you manage yourself is a reasonable choice, and a management fee would swallow too much of the money. Where a specialist starts to pay for itself is when the spend is large enough that a percentage of waste costs more than the fee, when there are several services with different economics, or when tracking and landing pages need to be built properly rather than approximated.

If you do want a second opinion on an account that is not performing, we will read the account and tell you what we see, including the answer that you do not need us. You can see how our Google Ads management works or the numbers from real accounts we run.
