The short answer
- There are two costs: ad spend (paid to Google) and management (paid to whoever runs the account).
- Most small businesses running effective campaigns spend $1,000 to $10,000+ a month on ads.
- Most service businesses pay $1 to $10 per click; competitive industries and emergency searches cost more.
- Management is usually a flat monthly fee or a percentage of spend, commonly from around $500 to $2,000+ a month.
- The number that matters is cost per booked job, not cost per click.
How Google Ads pricing actually works
Google Ads runs an auction every time someone searches. You never pay a fixed price per ad. On search campaigns you pay when someone clicks, and what you pay depends on how many other advertisers want that search, what they are willing to bid, and how good Google judges your ad to be.
That last part is Quality Score, built from three things: your expected click-through rate, how relevant your ad is to the search, and your landing page experience. A strong Quality Score can let you win the same position for less than a competitor with a weaker ad - which is why a well-built account often pays less per click than a neglected one in the same market.
You control spend with a daily budget. On busy days Google can spend up to twice your average daily budget, but across a month it will not charge more than your average daily budget multiplied by 30.4. So a $50 daily budget works out to a maximum of about $1,520 a month.
What drives your cost per click
- Industry. Legal, finance, insurance and emergency trades sit among the most expensive searches, because each customer is worth a lot.
- Location. Sydney and Melbourne are generally more competitive than smaller cities, so the same keyword often costs more there.
- Urgency. "Emergency plumber" costs more than "bathroom renovation ideas" because the searcher is ready to pay now.
- Match types and negatives. Broad keywords without negative keywords pull in irrelevant searches you still pay for.
- Time and device. Competition shifts across the day and between mobile and desktop.
How much ad spend do you need?
Most effective campaigns start at around $1,000 a month. Below that, it is hard to gather enough data to learn what works. The maths is simple: at an average of $5 per click, $1,000 buys about 200 clicks. If one in ten of those clicks becomes an enquiry, that is roughly 20 leads - enough to see which keywords and ads are producing work and cut the rest.
Spend scales with the work you can handle. There is no point buying 60 leads a month if you can only take on 20 jobs.
What management costs - and what to watch for
Management fees in Australia are usually structured one of three ways:
- Flat monthly fee - predictable, and not tied to how much you spend.
- Percentage of ad spend - scales with the account, commonly used at larger budgets.
- Hybrid - a base fee plus a percentage above a spend threshold.
Whichever model you choose, check three things before you sign anything:
- Is ad spend marked up? Every dollar of ad spend should go to Google. Caleb Marketing does not mark up ad spend.
- Is there a lock-in contract? If results are poor you should be free to leave.
- Who owns the account? The Google Ads account and its history should belong to your business, not the agency.
The calculation that matters: what can you afford per lead?
Work backwards from a real job, not from a click price:
Average job value × your close rate = what each lead is worth in revenue.
A $2,000 job with a 25% close rate means each lead is worth $500 in revenue. At a 40% margin, you break even paying $200 per lead - and anything below that is profit.
For a real reference point, a recent Google Ads campaign for a Queensland business ran at a $16 cost per lead with a 19.02% conversion rate, generating $30,000+ in revenue in 90 days. Your numbers will differ by industry, but that is the kind of gap between cost and value a well-built account should create.
Where Google Ads budgets get wasted
High costs are often not a bidding problem at all. The most common leaks are location targeting that includes people merely interested in your area, Search campaigns quietly running on the Display Network, broad keywords with no negatives, and no conversion tracking at all.

Frequently asked questions
What is the minimum budget for Google Ads in Australia?
Google has no minimum spend, but most effective campaigns start at around $1,000 a month in ad spend. Below that it is difficult to gather enough clicks and conversions to learn what works and cut what does not.
Does Google charge more than my daily budget?
On busy days Google can spend up to twice your average daily budget, but over a month it will not charge more than your average daily budget multiplied by 30.4.
How much does a Google Ads manager cost in Australia?
Management is usually a flat monthly fee, a percentage of ad spend, or a combination, commonly from around $500 to $2,000+ a month depending on budget and complexity. Check that ad spend is not marked up, that there is no lock-in contract, and that the account is in your business's name.
