What Google Ads actually costs in Australia
Google charges you per click, and the price of a click is set by what your competitors will pay for the same search and how relevant your ad and page are. There is no fixed rate: competitive commercial terms cost many dollars a click in Australian capitals, while niche and long-tail searches cost a fraction of that. The figure that matters is not cost per click but cost per customer.
What you are actually paying for
- Clicks, not views. Impressions are free; you pay when someone taps through.
- An auction price, not a rate card. You pay roughly what it takes to beat the advertiser below you.
- A discount for relevance. A more useful ad and page can win the same position for less.
- GST, applied to Australian accounts on top of the spend.
What makes a click expensive
| Driver | Effect |
|---|---|
| Value of the customer | High-value trades, legal and finance terms cost the most |
| Number of competitors | Capital cities cost more than regional areas |
| Search intent | "buy" and "near me" cost more than "how to" |
| Ad and page relevance | Better match, lower price for the same position |
| Time and device | Business hours on mobile is often the busiest auction |
Published averages are of limited use because the spread is enormous. The reliable way to find your own number is to check the real cost per click your account reports after a few hundred clicks.
The costs that are not clicks
- Management — agencies typically charge either a monthly retainer or a share of spend. Either way, add it to the cost of a customer before you judge the channel.
- Landing pages — often the highest-return spend in the whole exercise, and a one-off.
- Your own time — an hour a week reading search terms and answering enquiries quickly.
- Tools — anything you use to plan, report or schedule.
The number that matters
Three figures decide whether Google Ads works for you, and only one of them is about Google.
- 01Cost per click — what you pay for a visitor.
- 02Conversion rate — how many of those visitors enquire.
- 03Close rate — how many enquiries become paying work.
Multiply them out and you get cost per customer. A A$12 click is cheap if one in ten enquires and one in two buys. A A$2 click is expensive if nobody ever calls back.
Keeping the bill predictable
- Set a monthly total and a daily target, then watch the pace against it rather than checking the balance at the end.
- Cap where it matters: locations you service, hours you can answer the phone.
- Add negatives weekly — most overspend is wasted searches, not high bids.
- Keep brand searches in their own campaign so they do not disguise the real cost of new customers.
Common questions
- Is there a minimum spend for Google Ads?
- No minimum is imposed. The practical minimum is whatever buys enough clicks on your best terms to learn something in a reasonable time.
- Does Google charge a fee on top of clicks?
- No platform fee. You pay for clicks plus GST. Any management fee comes from an agency or freelancer, not from Google.
- Why did my cost per click go up?
- Usually more competitors in the auction, a seasonal peak, or a drop in your ad relevance. Check whether impressions rose at the same time before assuming it is you.
- Are Google Ads cheaper than Facebook or Instagram ads?
- Clicks are usually dearer on Google, because people are searching with intent rather than scrolling. Compare the two on cost per customer, not cost per click.
