Decision Framework

SEO vs Google Ads

Where should your next dollar of search budget go? Real cost math, real timing, no agency self-interest.

SEO
Compounds

Slower to start. Pays out for years. Your traffic when you stop paying = the traffic you keep.

Google Ads
Instant velocity

Live the day you launch. Stops the day you pause. Burns budget on every click, high or low intent.

The Fork

The wrong choice can waste a year of budget.

Every Perth business eventually asks: should we run Google Ads, do SEO, or both? And every agency has a self-serving answer, SEO agencies say SEO; ad agencies say Ads.

Here's the honest version. The right answer depends on your margins, sales cycle, urgency, and competitive set, not on which agency you're talking to.

The 3-year math

$108k either way. Only one of them leaves something behind.

A $3,000/month spend over 3 years is $108,000 in both columns. But by month 37, the SEO money has become a ranking website, hundreds of optimised pages, and ongoing organic traffic. The Ads money? Zero ongoing visitors.

SEO leaves you owning a compounding asset. Ads rent visibility, when the budget tap closes, the traffic does too.

The trap: A lot of businesses bail on SEO at month 4 because "it's not working yet", and miss the compounding payoff at month 6-9. SEO is delayed gratification with a high ceiling.

Trust & clicks

Australians click organic. By a wide margin.

Aggregated click-through-rate studies show position 1 organic gets 25-35% of clicks on most queries. The top ad? 3-10%. For research-stage decisions (B2B, healthcare, legal, financial), organic wins by an even wider margin.

For impulse purchases and urgent services, ads convert because intent is high. For everything else, users instinctively trust organic results more.

When each wins

Pick the situation that's most like yours.

Google Ads is right when…
You need leads now.
  • You need leads this week, this month, not in 6 months
  • Your product has urgent demand (emergency trades, time-bound offers)
  • Your unit economics support $20-$200 per click
  • You're testing a new market or product before long-term investment
SEO is right when…
You're playing the long game.
  • You can wait 3-9 months for results to compound
  • Customers research before buying (B2B, considered purchases)
  • Competitors dominate search and you want to take share
  • You're investing for the next 3-5 years, not 3 months
Most Perth businesses

Should do both.

Ads fill the pipeline now. SEO builds a moat that pays compounding dividends. The split depends on your stage and budget, and shifts as SEO kicks in.

Budget split over time

How the mix shifts as SEO compounds.

Rough rules of thumb that consistently work for our Perth clients.

Year 0-1
Get leads flowing.
Ads 70% SEO 30%
Year 1-2
SEO starting to land.
Ads 50% SEO 50%
Year 2+
Organic does the work.
Ads 30% SEO 70%

Your numbers will vary based on margins, competition, and sales cycle. But the trajectory is the same: shift budget from Ads to SEO as SEO compounds.

Decision framework

Which scenario are you?

Scenario 1

"We need leads now, can't wait 6 months."

Recommendation: Start with Google Ads. Layer in SEO in parallel from month 3.

Scenario 2

"We've got demand, we need to defend our rankings."

Recommendation: SEO-heavy with branded Ads for top-of-SERP protection.

Scenario 3

"New business, no budget for both."

Recommendation: Depends on margins. High-margin (>50% gross) + urgent demand: Ads first. Lower margins or long sales cycle: SEO first.

Scenario 4

"We've done Ads for 2 years, CPA keeps creeping up."

Recommendation: Pivot 30-50% of that budget to SEO. Ads CPAs rise with competition; SEO compounds in the opposite direction.

"We've been running both SEO and Google Ads campaigns for Perth businesses since 2007. The cleanest signal we see: the clients who let SEO run for 12 months end up spending less on Ads, and earning more. The two aren't enemies. They're a sequence."
