It's the first question almost every business owner asks me about Google Ads, and it's the hardest one to get a straight answer to online. Search it and you'll get a wall of "it depends" with no actual numbers. So here are the real ones, for a Cairns business, in plain English.
The short answer
There's no fixed price. You set the budget. Most small Cairns businesses I work with run somewhere between $1,000 and $3,000 a month in ad spend to get a steady flow of enquiries. Some trades start lower at $500–$800 to test the water. Bigger or more competitive jobs go higher. The point is you're in control of the dial, not Google.
What you're really paying for breaks into two parts: the money that goes to Google for the clicks, and (if you use one) the fee for the person managing it.
Part 1: what you pay Google
Google Ads is an auction. You pay each time someone clicks your ad — that's the cost-per-click, or CPC. What you pay per click depends on how many other businesses want that same search.
In Cairns, the spread is wide. A click for something like "plumber Cairns" or "emergency electrician" can run $4 to $12 because the work is worth a lot and everyone's bidding for it. Softer searches — a service that's less urgent or less contested — can sit under $2. The high-value, ready-to-buy searches cost the most, because they're the ones worth winning.
Quick example. Say your clicks average $5 and you spend $1,500 a month. That's about 300 clicks. If even 1 in 10 of those people calls or fills in your form, that's 30 enquiries. Close a third of those and the budget has paid for itself many times over for most trades. That's the maths that actually matters — not the click price on its own.
Part 2: management fees
You can run Google Ads yourself. Plenty of people do, and plenty of people quietly waste a few thousand dollars learning what doesn't work. A managed account costs more upfront but the job of management is to stop you paying for clicks that were never going to call you.
Management is usually either a flat monthly fee or a percentage of your spend. The honest version of this service earns its fee by making the ad spend work harder — tighter targeting, killing the searches that burn money, and pointing the ads at a page that actually converts.
The bit most people miss
The ad budget isn't the whole cost. Where you send the click matters just as much. If your ad is sharp but it lands on a slow, vague page, you've paid for the click and lost the lead. Half of getting Google Ads right is having a page that does its job once the visitor arrives — which is the same reason your website needs to pull its weight as a lead generator.
So is it worth it?
Google Ads buys you the top of the page tomorrow. SEO earns it over months — cheaper per lead long-term, slower to start. Most Cairns businesses I work with do both: Ads for leads now, SEO building underneath so they're not renting their visibility forever. I've broken that trade-off down in Google Ads vs SEO if you want the full comparison.
The honest bottom line
Budget on $1,000–$3,000 a month in spend for a small Cairns business, expect clicks in the $2–$12 range depending on how competitive your work is, and add a management fee if you'd rather not learn it the expensive way. The number that counts isn't the click price — it's what a new customer is worth to you, and how many of them the budget brings in.
