If you’re weighing up Google Ads against SEO, you’re really answering one question: do you pay for leads this week, or invest in a ranking that keeps working for years? There’s no single right answer — but there is a reliable way to decide, and it comes down to three things: how fast you need results, what it costs, and what you keep when you stop paying. It’s a decision that’s getting more pressing as ad costs climb, and getting it right can save you thousands over the next year.
The short answer
Both Google Ads and SEO put your business in front of people searching for exactly what you sell. The difference is how they get you there, and when the results show up.
- Google Ads buys visibility now. You pay for each click and can be in front of customers within days. The traffic stops the day you stop paying.
- SEO earns visibility over time. You build a ranking that sends ongoing organic traffic — and you keep the asset long after the heavy lifting is done.
Most Melbourne businesses don’t need to choose one forever. They need to know which one fits the stage they’re at right now — and in practice, the two often work best side by side.
How fast do you need results?
This is usually the deciding factor, so it’s worth being honest about both sides.
Google Ads is fast. A well-set-up campaign can start sending clicks to your site within days, which makes it the natural choice when you need enquiries this month — a new service launch, a quiet season to fill, or a gap you can’t afford to sit through. Speed buys you cash flow and confidence while everything else catches up.
SEO is a longer game. Research by Ahrefs across roughly a million pages found that only 1.74% of newly published pages reach Google’s top 10 within a year. The encouraging side of the same study: of the pages that do break into the top 10, 40.82% get there within the first month. In other words, SEO can move quickly when it works — but most new pages never get there at all.
That’s not an argument against SEO. It’s an argument for entering it with honest expectations: treat it as a six-to-twelve-month investment, not a switch you flip for instant traffic.
What does it cost — and what do you keep?
Here’s where the two part ways on money, and the difference matters more than the sticker price.
Google Ads charges per click, and Melbourne commercial keywords don’t come cheap. As a point-in-time snapshot of the market, competitive terms run roughly $15–31 AUD per click. That’s a marketplace average, not a quote — but it tells you the scale: a thousand clicks can cost well over $15,000 before a single one turns into a customer.
It’s also getting more expensive to convert those clicks. WordStream’s benchmark data shows cost per lead rose for 91% of industries year-on-year — up 19% on average — while conversion rates fell 14%, with a typical cost per lead around $40 US. None of that makes ads a bad idea; it makes them a cost worth watching closely, and it raises the value of every enquiry that does come through.
The bigger question is what happens when you stop. With Google Ads, stop paying and the traffic stops. With SEO, the ranking you’ve built usually keeps working for you — not forever, and not without ongoing upkeep, but you’re not feeding a per-click meter the whole way.
That’s the real difference in “cost”: ads are a recurring expense, while SEO is closer to an asset you build. Both need a budget. One keeps billing you; the other keeps working for you.
The middle path: run both, and phase the balance
You don’t have to pick one. Plenty of Melbourne businesses run Google Ads and SEO at the same time, and the smart ones shift the balance as the results come in.
Start ads-heavy. While you’re new to search and have no rankings to speak of, ads buy you the visibility and the leads you can’t afford to wait for. At the same time, start the SEO work — because it takes months to compound, every month you delay is a month longer before it pays.
Then, as your rankings strengthen and organic traffic grows, dial the ads back on the terms you now rank for. You stop paying for clicks you’re earning for free, and you reinvest that budget into the next set of keywords. Over time, the mix shifts from mostly paid to mostly owned.
The aim isn’t to eliminate one or the other. It’s to make sure every dollar of ad spend is doing a job SEO can’t do yet — and to retire it the moment SEO can.
How to decide for your business
Strip it back to two questions:
- Do you need enquiries this month? Start with Google Ads and let it carry you while something slower builds.
- Can you wait six to twelve months for an asset you own? Invest in SEO and let it compound.
A concrete example: a plumber who needs urgent jobs this week should start with ads, because those searches are immediate and local. A mortgage broker building a reputation over two years gets more from SEO, where ranking for a term like “mortgage broker Melbourne” pays off month after month without a per-click bill.
For a lot of Melbourne businesses, the honest answer is both — run ads now to keep cash flowing while SEO builds in the background. Ads give you the speed; SEO gives you the staying power.
