SEO vs Google Ads: Which Should You Invest In?

When it comes to growing your business online, two heavyweights dominate the conversation: Search Engine Optimisation (SEO) and Google Ads (Pay-Per-Click). Both can drive traffic, leads, and revenue – but they work in fundamentally different ways, and choosing the right one (or the right mix) depends on your goals, budget, and timeline.

At Salt Agency, we’ve helped dozens of Brisbane businesses navigate this exact decision. We build high‑end websites, create performance‑focused content, and execute both organic and paid strategies under one roof. So we know: there’s no one‑size‑fits‑all answer. But by the end of this article, you’ll have a clear framework to decide where to invest your marketing dollars.

What’s the Difference Between SEO and Google Ads?

Before we compare them head‑to‑head, let’s quickly define each channel.

SEO (Search Engine Optimisation)

SEO is the long‑term process of improving your website’s visibility in organic (non‑paid) search results. It involves technical optimisation, on‑page content, backlink building, and user experience improvements. Done right, SEO delivers sustainable, compounding traffic that keeps coming month after month without direct ad spend.

Google Ads (Pay‑Per‑Click)

Google Ads places your business at the top of search results (or across the Display Network) for specific keywords. You pay only when someone clicks your ad. It’s fast, highly targeted, and gives you immediate visibility – but the moment you stop paying, the traffic stops.

When Should You Invest in SEO?

SEO is the foundation of any strong digital presence. If you’re building a brand that you plan to own for years, SEO is non‑negotiable.

You’re Playing the Long Game

Businesses that invest in SEO are building an asset. Every piece of content, every backlink, every technical improvement compounds over time. Once you rank on page one for a high‑value keyword, you’ll keep getting traffic without paying per click. For a Brisbane-based agency like ours, that means clients see their organic traffic grow month‑on‑month, ultimately reducing their reliance on paid ads.

You Want Cost‑Effective, Scalable Growth

Yes, SEO requires an upfront investment. But the cost per acquisition (CPA) of organic traffic is often far lower than paid traffic – especially for competitive keywords. As your authority grows, you can capture more keywords without increasing your budget.

You’re Building Trust and Authority

Organic rankings signal to users that Google trusts your site. That trust translates into higher conversion rates. If you’re in a space where credibility matters (legal, medical, finance, or high‑ticket services), SEO is essential.

When SEO alone might not be enough: If you need customers today – for a new product launch, a limited‑time offer, or a seasonal spike – SEO’s slow ramp‑up can be a problem.

When Should You Invest in Google Ads?

Google Ads is the ultimate accelerator. It gets you in front of people searching for your product or service right now.

You Need Immediate Results

If you’re launching a new business, a new location, or a time‑sensitive promotion, Google Ads is your friend. You can set up a campaign in hours and start seeing clicks within minutes. For a local tradie or a new restaurant in Brisbane, that speed can make or break a launch.

Your Keywords Have Strong Commercial Intent

Some search queries are pure gold. “Plumber near me”, “buy running shoes online”, or “Brisbane wedding photographer” – these searches show clear intent to purchase or book. Google Ads lets you bid on exactly those terms and appear above the organic results.

You Want to Test, Measure, and Scale Quickly

Paid ads give you precise data: cost per click, conversion rate, return on ad spend. You can test different headlines, landing pages, and audiences, then scale what works. If you’re a data‑driven marketer, Google Ads feeds your need for measurable ROI.

When Google Ads alone might be a trap: Relying solely on paid traffic means you’re renting your visibility. The moment you pause your campaigns, your traffic flatlines. It can also become expensive in competitive industries if your landing page experience isn’t optimised.

The Sweet Spot: Combining SEO and Google Ads

At Salt Agency, we often tell clients: “Don’t choose – combine.” A balanced digital marketing strategy uses both channels to complement each other.

• Use Google Ads to capture immediate demand while your SEO efforts gain traction. This is especially powerful for a new website that hasn’t yet built authority.
• Use SEO to dominate lower‑funnel keywords over time, reducing your paid spend on high‑cost terms.
• Retarget organic visitors with paid ads to bring them back and convert. If someone visits your blog via organic search, a well‑timed Google Display ad can seal the deal.
• Leverage SEO data to improve your Google Ads. The keywords that drive the best organic performance often make excellent paid keywords, and vice versa.

For example, one of our clients – a Brisbane‑based service business – started with Google Ads to generate leads within two weeks, while we simultaneously built out their site’s SEO foundation. After six months, organic traffic had grown 300%, and they halved their paid ad budget without losing leads. That’s the power of a combined approach.

Which One Is Right for Your Business?

Ask yourself these three questions:

1. How quickly do you need results?

– Immediate → Lean into Google Ads.

– Within 6–12 months → Invest in SEO.

– Mix of both → Do both.

2. What’s your budget?

– Limited budget → Start with SEO (if you have time) or Google Ads (if you need fast ROI on a small, targeted campaign).

– Healthy budget → Allocate 60–70% to SEO and 30–40% to Google Ads, adjusting based on performance.

3. What’s the lifetime value of your customers?

– High LTV (e.g., professional services, membership sites) → SEO is critical – you want that long‑term traffic.

– Low LTV (e.g., one‑off purchases) → Google Ads can work well if you can manage CPA.

Frequently Asked Questions

Can I do SEO myself?

You can learn the basics, but competitive SEO is complex – technical audits, content strategy, link building, and ongoing monitoring. Most businesses get better ROI by partnering with an agency like Salt Agency that has the expertise and tools to deliver results.

How much does SEO cost in Australia?

SEO pricing varies widely depending on scope. Typical monthly retainers for a comprehensive SEO program range from $2,000 to $10,000+. At Salt Agency, we offer custom packages tailored to your business goals.

Is Google Ads a waste of money for small businesses?

Not at all – provided you have a tight budget, well‑targeted keywords, and a compelling landing page. Smaller budgets can still drive high‑intent traffic. The key is constant optimisation.

Should I stop Google Ads once my SEO is working?

Not necessarily. Many businesses keep a small paid campaign running for high‑value keywords to ensure they capture traffic even if organic rankings fluctuate. A balanced approach is usually best.
