“How much do Google Ads cost?” is one of the first questions business owners ask us. The honest answer is “it depends”, which isn’t much use on its own.
So this guide covers what it depends on, what the numbers actually look like, and a simple way to work out a budget that makes sense for your business.
The short answer
• There’s no fixed price. You set a budget and pay each time someone clicks your ad.
• What a click costs depends on your industry, your competitors and how good your ads are. It can be under a dollar or well over $10.
Plan for two costs: your ad spend (paid to Google, plus 10% GST) and the cost of managing it (your time, or an agency’s fee).
How Google Ads pricing works
• For standard search ads, you don’t pay for your ad to be shown. You pay when someone clicks it. That’s your cost per click (CPC).
• Every search triggers a quick auction between the businesses that want to appear for it.
• The winner isn’t simply whoever bids the most. Google also weighs how relevant your ad and landing page are (your Quality Score). A more relevant ad can beat a bigger bid.
• You set a daily budget. Google can spend up to twice that on a busy day, but over a month it won’t charge more than your daily budget × 30.4.
• Australian advertisers pay 10% GST on top of their ad spend. If you’re GST-registered you can generally claim it back like other business expenses (check with your accountant).
The five things that drive your cost per click
1. Your industry. Where one customer is worth a lot (legal, finance, trades doing big jobs), competitors are willing to bid more.
2. How many competitors are bidding. A plumber in Sydney’s inner west faces far more competition than one in a regional town.
3. How ready to buy the searcher is. “Emergency plumber near me” costs more than “how to fix a leaking tap”, because it’s much closer to a sale.
4. Your ad quality. Relevant ads, matching landing pages and fast-loading pages all lower what you pay.
5. When and where you show. Peak hours and big-city targeting usually cost more.
What does a click cost? The benchmarks
Google doesn’t publish Australian cost-per-click figures by industry. The biggest public study comes from WordStream and LocaliQ, which analysed 13,474 US search campaigns between April 2025 and March 2026. Across all industries, the average was US$5.42 per click and US$66.69 per lead.
• The gap between industries is huge. A click in legal costs around six times as much as one in arts and entertainment.
• Industries where one job is worth thousands (legal, dental, home improvement) sit at the top.
• Use these as a guide to which industries are expensive, not as Australian prices. Your own market and keywords matter far more.
So what’s the minimum budget?
Our rule of thumb: your budget should buy at least 100 clicks a month in the campaign that matters most. Below that, it’s hard to tell what’s working, and Google’s automated bidding has too little data to learn from.
Signs you’re paying more than you need to
• No conversion tracking, so Google optimises for clicks instead of enquiries.
• Broad keywords with no negative keywords, so you pay for irrelevant searches (like “plumber jobs” when you’re not hiring).
• Every ad sends people to your homepage instead of a page that matches what they searched for.
• Ads showing across all of Australia when you serve 20 suburbs.
• Ads running 24/7 when nobody answers the phone after 5pm.
• Automated campaigns, like Performance Max, running with no exclusions or checks on where your money goes.
Common questions
Can I run Google Ads for $10 a day?
You can, and Google will happily take it. But at $5 a click that’s only about 60 clicks a month, which makes it hard to learn anything. It can work in a cheap, low-competition niche.
Do I pay if nobody clicks?
Not for standard search ads. Some other campaign types, such as display and video, can be charged differently, so check how each campaign is billed.
How quickly will I see results?
Search ads can bring in enquiries in the first week. But expect four to eight weeks of testing and refining before your costs settle.
