You've got a marketing budget that needs to work. One agency tells you Google Ads will put you in front of buyers this week. The next tells you SEO is the only way to build something that lasts. A third says you should do both, without being specific about what that mix should look like or what each channel is supposed to carry.
The either/or framing is a big part of the reason this decision feels harder than it should. SEO and Google Ads solve different problems. The question that matters is how to weight them for where your business sits right now.
At CJ Digital, a digital marketing agency in Hawthorn, we run both SEO and Google Ads for Melbourne clients, which means we spend a lot of time walking business owners through the split. Here is how to think about it, what each channel does on its own, and what a sensible starting mix looks like in 2026.
Google Ads places your business at the top of Google's search results in return for a bid on each click. Visibility is immediate. Campaigns can run the day they go live. You pay per click, and the price per click depends on your industry, the competitiveness of the keyword, and the quality of your ads and landing page. When the budget stops, the visibility stops.
Search engine optimisation (SEO) is the work that earns organic (unpaid) rankings on Google. That includes the technical health of the site, the content on it, and the links pointing to it from other websites. SEO is slow to start. A business in a competitive category can expect three to six months before meaningful organic traffic arrives, and twelve months before the compounding becomes obvious. When the work stops, rankings do not fall off a cliff the way paid visibility does. Good SEO continues to deliver months after a campaign pauses.
Treating SEO and Google Ads as rival budgets misses what each channel gives the other. When both run in parallel, four things tend to happen.
There are business stages and conditions where a heavy Google Ads weighting is the right call, sometimes with SEO on the back burner entirely until cash flow allows otherwise.
The three most common mixes map to different business stages. Read the table below as a rough guide. It is not a formula. A tradie competing against established franchise brands in a booked-out market runs a different mix to a five-year-old professional services firm with strong referrals and a weak website.
| Mix (Ads / SEO) | Where it fits | What Ads carries | What SEO carries | Caveat |
|---|---|---|---|---|
| 80 / 20 | New business, no organic base, cash flow needed now | Immediate enquiries and brand exposure | A slow foundation for year two | SEO spend is too light to deliver within 12 months. Treat as a holding pattern. |
| 50 / 50 | Established business with some organic visibility, building long-term share | Short-term lead volume and keyword conversion data | Compounding traffic on core service terms | The most flexible mix. Works for the widest band of businesses, though it is not the default answer for everyone. |
| 20 / 80 | Mature business with strong organic rankings, using Ads only for gaps | Remarketing, brand defence, seasonal pushes | The bulk of lead flow | Only viable once SEO rankings are established. Moving here too early leaves money on the table. |
There is a floor below which neither channel works. Too little on Google Ads produces too few clicks to refine the campaign. Too little on SEO stretches the work over years rather than months, or leaves it unable to move rankings at all.
For the Australian market in 2026, a credible combined program sits somewhere between around $3,200 and $11,000 per month across both channels, depending on industry, competition and how aggressive you want the SEO investment to be. The ranges below are indicative for budgeting. They are not quotes, and they will vary by industry, competition and which agency you work with.
| Channel | Indicative monthly spend (2026) | What it buys |
|---|---|---|
| Google Ads (media plus management) | $2,500 to $5,000 | Enough click volume to refine the campaign, plus a specialist to run bids, landing pages and reporting |
| SEO retainer | $700 to $6,000 | Technical fixes, monthly content, link work, reporting |
Pricing disclaimer: Australian market ranges as at April 2026, for indicative budgeting only. Prices vary by industry, competition and agency.
Below that floor, one channel or the other will underperform. Spreading a smaller budget across both usually produces two underfunded campaigns. The better play is to pick one channel, run it properly, and add the second when the budget allows.
Before you decide on a split, run through the following.
There are businesses where the answers point clearly in one direction, and businesses where they point in both. Plenty of businesses land at 50/50. Plenty do not. The split should reflect where you sit on each of the questions above.
The split between SEO and Google Ads is not a one-time call. The right weighting at launch is rarely the right weighting at year three. A business that sits still on the same mix for too long usually finds itself either overspending on Ads it no longer needs or underinvesting in SEO that is about to pay off. Review the split every six months, and treat any significant change in trading conditions (new competitor, new service line, shift in sales cycle length) as a trigger to look again.
If you want a second opinion on where your business sits in that range, send us a short note about your stage, your category and what you are currently spending. We'll tell you straight which mix fits, whether the numbers you are working with now will get you there, and what the first three months of a combined program should cover.
