Short answer: use Google Ads for high-intent, local or B2B services where people are already searching for a solution; use Meta Ads for visual, new-to-market or e-commerce products that need to create demand; and for most Australian SMBs, run both - typically 70% Google Ads / 30% Meta for service businesses, or 40% Google Ads / 60% Meta for e-commerce.
The most common question Australian business owners ask their Google Ads or Facebook advertising agency is: "Which platform should I be on?" The honest answer is that it depends on your business model, sales cycle, and budget - but the smartest answer is usually both, deployed strategically.
The Fundamental Difference
Google Ads captures existing demand. When someone searches "emergency plumber near me," they need a plumber right now. Google Ads puts you in front of people actively looking for what you sell.
Meta Ads creates new demand. When someone scrolls Instagram and sees a compelling ad for a product they didn't know existed, Meta has generated interest where none existed before. For offers that benefit from demonstration or longer-form explanation, YouTube advertising can add video discovery and remarketing to the same media plan.
This distinction is critical for choosing the right platform - or the right budget split between them.
When Google Ads Wins
- High-intent services: Plumbing, legal, medical, emergency services - anything people search for when they need it now
- Local businesses: "Near me" searches drive immediate foot traffic and calls
- Known solutions: When people already know what they want and are comparing providers
- B2B with defined buying cycles: Decision-makers actively researching solutions
When Meta Ads Wins
- Visual products: Fashion, food, home decor - anything that sells through imagery
- New-to-market products: Innovations people do not know to search for yet
- Brand building: Awareness campaigns that create future demand
- E-commerce: Especially with Meta's shopping and retargeting capabilities
- Younger demographics: Instagram and Facebook reach audiences where they spend time
Cost Comparison: Australia 2026
Google Ads average CPC in Australia: $2.50 - $8 (general), $15, $80 (competitive verticals). Meta Ads average CPM: $8 - $25 (depending on targeting and creative quality - see our Facebook Ads cost guide for a full breakdown). Meta typically delivers a lower cost per impression but Google often delivers a lower cost per conversion for high-intent services.
The Smartest Approach: Full-Funnel Integration
The highest-performing Australian businesses do not choose one platform - they use both strategically:
- Meta Ads for awareness: Video and carousel ads introduce your brand to cold audiences
- Google Ads for capture: Search ads capture the demand Meta created when prospects search for solutions
- Meta retargeting: Re-engage website visitors who did not convert on their first visit
- Google remarketing: Stay visible across the Google Display Network and YouTube
This full-funnel approach, which our social media advertising team builds for clients, typically delivers 30 - 50% higher ROAS than single-platform campaigns.
Budget Split Recommendations
For most Australian SMBs, we recommend starting with:
- Service businesses: 70% Google Ads, 30% Meta Ads
- E-commerce: 40% Google Ads, 60% Meta Ads
- Brand-new businesses: 50/50 split for first 90 days, then optimise based on data
The Bottom Line
Google Ads and Meta Ads are not competitors - they are complementary channels that serve different stages of the buyer journey. The businesses winning in 2026 are those that partner with a PPC agency to orchestrate both platforms as a unified paid media strategy rather than running them in silos - and pair that with the sequencing advice in our PPC vs SEO guide.

How the two auctions actually work
Google Ads and Meta Ads both run auctions, but they are solving different problems. Google's Search auction ranks advertisers primarily on a combination of bid and Quality Score, which itself reflects expected click-through rate, ad relevance and landing page experience, as Google explains in its own Google Ads management documentation on Quality Score.
Because the ad only appears when someone types a relevant query, the platform is matching supply to a demand signal that already exists. Meta's auction instead optimises for the outcome you tell it to chase - clicks, leads, purchases, and so on - by predicting who in a given audience is most likely to take that action, based on the account's pixel or Conversions API data and the ad's historical performance.
This is why a Meta account with little conversion history often performs poorly at first: the algorithm has not yet learned who converts, whereas a new Google Ads account for a well-defined search term can perform reasonably from day one because the intent signal is already explicit in the query itself.
Creative and targeting: different skills, different failure points
A Google Search ad succeeds or fails mostly on relevance between the keyword, the ad copy and the landing page - get those three aligned and the rest is largely about bid strategy and budget. A Meta ad succeeds or fails mostly on the creative itself, because it is interrupting someone's feed rather than answering a question they just asked. This means the two channels demand different internal skills and different review processes.
A business that is strong at writing precise, benefit-led search ad copy is not automatically equipped to produce the volume of fresh video and image creative that Meta campaigns need to avoid audience fatigue.
Creative fatigue is a genuine, recurring cost on Meta - the same ad shown repeatedly to the same audience loses effectiveness over time, so a Meta program needs an ongoing supply of new creative variations, whereas a mature Google Search campaign can often run largely unchanged for long stretches once the account structure and keywords are settled.
What to ask before committing budget to either platform
- What does the account structure look like, and is it organised around your actual services or product categories rather than generic themes
- How is conversion tracking configured, and has it been checked against actual leads or sales rather than just platform-reported numbers - our guide to setting up Google Ads conversion tracking covers what correct tracking looks like
- What creative refresh cadence is planned for Meta campaigns, and who is responsible for producing new assets
- How will results be reported, and does that reporting distinguish between platform-attributed conversions and verified leads or sales in your own systems
- What is the plan for the first 60 to 90 days, when a new account - particularly on Meta - is still in a learning phase and performance is likely to be less stable
Prices for managing either platform are quoted per scope, since the right level of hands-on management depends on budget size, number of campaigns and how much creative production is involved.
Common mistakes when comparing the two platforms
The most common mistake is comparing raw cost metrics - CPC against CPM - as though they measure the same thing, when they describe different stages of the funnel. A second common mistake is judging a new Meta campaign on its first week of data, before the algorithm has had a chance to learn from enough conversion events.
A third is running both platforms with completely separate, disconnected messaging, so a prospect who saw a Meta awareness ad and later searches on Google encounters an entirely different offer or tone, which undermines the consistency that makes full-funnel advertising effective.
A fourth is neglecting the landing page: both platforms can drive qualified traffic, but if the landing page is slow or unclear, neither channel will convert well, which is why landing page best practices and basic technical SEO fundamentals matter regardless of which ad platform sends the visitor there.
How to sanity-check an agency's platform recommendation
If an agency recommends one platform over the other, ask them to explain the recommendation in terms of your buying cycle and existing search demand, not just a general rule of thumb. A business with a long, considered purchase - a family lawyer or a mortgage broker, for example - usually has real, if lower-volume, active search demand worth capturing with Google Ads, alongside longer-term brand-building on Meta.
A business selling an impulse or visually driven product usually needs Meta to do more of the early-funnel work. Ask to see how the agency plans to measure success on each platform separately before it recommends a specific budget split, and be wary of a proposal that quotes a single blended return figure without breaking down how each channel is tracked.

Reporting and what "working" actually looks like
Whichever platform or mix you choose, the reporting should tie back to real business outcomes rather than platform vanity metrics. For a service business, that means matching platform-reported leads against calls, form submissions and, ideally, jobs actually booked. For an e-commerce business, that means checking platform-reported purchases against actual order data, since attribution models on both Google and Meta can overstate their own contribution when a customer was influenced by more than one channel.
Agreeing on this reporting method before the campaigns launch - rather than after the first month of results - makes it far easier to judge honestly whether the budget split between Google Ads and Meta Ads management is actually working, and to adjust it based on evidence rather than platform preference.
