How Much Should a Wollongong Business Spend on Google Ads?

Written by Ryan Dalle-Nogare, Founder and Managing Director at Adcraft Studio.

It is the first question almost every business owner asks before they run a single ad. How much should you actually spend on Google Ads? The honest answer is that there is no fixed price, because Google Ads works like an auction. You set the budget, and what you get back depends on your industry, your goals, and how well your campaigns are built. A plumber in Wollongong and a law firm in the Illawarra can both run successful campaigns, but they will spend very different amounts to do it.

The good news is that you can work out a sensible starting number with a bit of simple maths. This guide breaks down what your money pays for, what a realistic budget looks like for a local business, and how to tell whether your spend is turning into real revenue. The goal is to help you spend with confidence instead of guessing, so every dollar has a job to do.

What you actually pay for with Google Ads

Google Ads runs on a cost per click model. You only pay when someone clicks your ad, not when it simply shows up in the results. The price of each click is set by an auction that happens every time a person searches. Your competitors bid, Google looks at the quality of everyone's ads, and the winner gets the top spot. This means your cost per click moves up and down based on how many other businesses want the same customers you do.

In Australia the average cost per click sits somewhere around two to four dollars for most local service businesses. Some industries are far more expensive. Legal, finance, and trades can push well past ten dollars a click because each new customer is worth so much. Quality matters too. Google rewards ads that are relevant and useful with a higher Quality Score, and a strong score can cut your cost per click dramatically. A poorly built campaign can pay several times more for the exact same click, which is why setup and management make such a difference to the final bill.

A realistic starting budget for a Wollongong business

For most small and medium businesses in Wollongong, a starting budget of around fifteen hundred to three thousand dollars a month is a sensible range. That figure is not pulled from thin air. At average local click costs, this gives you enough clicks each day to gather real data within the first month, which is what Google needs before its system can optimise properly. Spend much less than this and your campaign can starve. It never collects enough information to learn what is working, so it keeps guessing.

Think of your first month or two as buying information, not just clicks. You are paying to find out which keywords bring buyers, which ads get the most response, and which times of day convert best. Once you have that data, you can scale up the parts that work and switch off the parts that waste money. Our Google Ads management team in Wollongong usually starts clients at a level that is high enough to learn quickly but controlled enough to limit risk while the campaign finds its feet.

How your industry changes the number

The single biggest factor in your budget is the kind of business you run. A cafe selling a fifteen dollar lunch cannot afford the same cost per click as a builder quoting on a two hundred thousand dollar renovation. The maths is simple. The more a single customer is worth to you, the more you can afford to pay to win one.

This is where lifetime value matters. If a new client spends five hundred dollars with you once and never returns, your budget needs to be tight. If that same client stays with you for years and refers their friends, you can afford to bid harder and outspend competitors who only think about the first sale. Before you set a number, work out what an average customer is really worth over the whole time they deal with you. That figure tells you how aggressive your Google Ads spend can safely be, and it stops you from setting a budget that feels cheap but actually leaves money on the table.

The hidden costs most people forget

Your ad spend is only part of the picture. The money you pay Google is the media cost, but there are two other costs that decide whether the whole thing works. The first is management. Whether you do it yourself or hire an agency, someone has to build the campaigns, write the ads, watch the numbers, and make changes every week. A campaign left alone will drift and waste money fast.

The second cost is where the clicks land. You can run perfect ads and still lose money if your website lets you down. A slow, confusing, or dated page will turn away the very people you paid to attract. Sending paid traffic to a weak page is like filling a bucket with a hole in it. This is why a sharp landing page or a well built custom website often does more for your return than simply adding to the ad budget. When you plan your spend, set aside thought and money for the page people see after they click, not just the click itself.

How AI is changing what your budget buys in 2026

Search has changed a lot in the last year, and it affects your budget directly. Google now shows AI Overviews at the top of many results, where the system answers the question itself before any normal links appear. For a lot of businesses this has pushed organic clicks down, because people read the AI answer and never scroll. The result is that paid ads, which sit above and around these AI answers, are getting more of the attention that used to go to free listings.

For a Wollongong business this matters in plain revenue terms. If fewer people are clicking the free results, the paid spots become more valuable, and showing up there can be the difference between getting the call and losing it to a competitor. Google has also rolled out more automated and AI driven campaign types that can stretch a budget further when they are set up well, but they can also burn money quickly when they are left on default settings. The lesson for 2026 is that smart management matters more than ever. The platform is doing more on its own, so the value now comes from steering it, setting the right goals, and feeding it good data so it chases real customers rather than cheap clicks. Across the search network the average conversion rate now sits around seven and a half per cent, which shows there is still strong revenue to be won when campaigns are built properly, according to WordStream's industry benchmarks.

How to know if your spend is working

A budget only makes sense when you can measure what it brings back. The number that matters most is your return on ad spend, often shortened to ROAS. It tells you how much revenue you earn for every dollar you put in. If you spend two thousand dollars and it brings ten thousand dollars in sales, your campaign is clearly paying for itself. If you cannot answer that question, you are not measuring properly, and that is the real problem to fix before you worry about the size of the budget.

To track this you need conversion tracking set up correctly, so every lead, call, and sale is counted back to the ad that caused it. Without it you are flying blind, and you will not know which keywords make money and which quietly drain it. Once tracking is in place, you can make calm decisions based on facts. You raise the budget on the campaigns that earn and cut the ones that do not. This is the part that separates a campaign that grows a business from one that simply spends money. Good measurement turns Google Ads from a cost into an investment you can size with confidence.

Should you put the money into Google Ads or somewhere else

Google Ads is fast. You can switch it on today and have customers calling tomorrow, which makes it brilliant for businesses that need leads right now. The trade off is that the moment you stop paying, the leads stop too. That is the nature of paid search. It works for as long as you fund it.

This is why many Wollongong businesses run Google Ads alongside search engine optimisation. Ads bring quick wins while your organic rankings build up over months, and once those rankings are strong they keep bringing traffic without a click fee. The smartest budgets often split between the two, using ads for speed and SEO for long term value. If you are not sure how to divide your spend, that is exactly the kind of plan our marketing team maps out before a single dollar goes live, so the budget matches your goals rather than a guess.

Setting a budget you can grow

The best approach is to start at a level you are comfortable testing with, prove that it works, and then scale. Begin with enough to gather real data, usually that fifteen hundred dollar a month floor for a local business. Give it sixty to ninety days with proper management and tracking. Watch your return on ad spend, and once you can see clear profit coming back, increase the budget on the winning campaigns. This way you never gamble a big number on an unproven idea. You grow your spend in step with your results.

Avoid two common traps. The first is spending too little and giving up before the campaign has had a chance to learn. The second is throwing a large budget at a campaign with no tracking, no management, and a weak website to land on. Both waste money for different reasons. A budget that starts sensible, gets measured honestly, and grows with proof behind it is how a Wollongong business turns Google Ads into a steady source of customers rather than a monthly expense it cannot quite explain.

Frequently asked questions

What is the minimum I should spend on Google Ads each month?

For most local businesses, around fifteen hundred dollars a month is a sensible floor. That gives Google enough clicks and data to optimise within the first month. Spending much less can starve the campaign so it never learns what works, which makes the whole effort less efficient and harder to measure.

Does a bigger budget guarantee better results?

No. A bigger budget only helps once the campaign is proven. Money poured into poor targeting, weak ads, or a slow website still gets wasted. It is far better to start smaller, measure your return on ad spend, fix what is not working, and then scale the parts that clearly bring revenue.

How long before Google Ads starts paying off?

Most campaigns need sixty to ninety days of proper management before they settle and the data becomes reliable. You can get leads in the first week, but the early period is about learning and adjusting. The campaigns that win are the ones that get refined over time rather than set and forgotten.
