Platform-by-Platform: Where Australian Brands Are Actually Seeing Social Media ROI Now

No single platform gives every Australian brand the best social media return. In our reading of the evidence, Meta (Facebook and Instagram) is the most common starting point for retail, consumer and local-service lead generation, and it is where advertisers concentrate.

In Metricool’s 2026 Social Ads Report, which covers 628,969 Meta and TikTok campaigns, 91% of advertisers ran on Meta only. That shows where money goes, not where returns are highest. LinkedIn shows the strongest measured returns for B2B in Dreamdata’s 2026 LinkedIn Ads Benchmarks Report, but that data is vendor-sourced and not Australian, and the returns arrive slowly.

TikTok and YouTube depend heavily on creative, and the evidence behind them is thinner. What decides it for your business is your margin, how long customers take to buy, whether the platform can reach them, and whether you can measure what happens after the click.

One caution on the word “actually”. We found no public Australian study that ranks platforms by return and shows its method, so this guide does not claim to name the Australian winner. Most figures you will see are global, vendor-sourced or unexplained.

Instead, it separates measured data from opinion, shows why the numbers contradict each other, adds the Australian context that changes the picture in 2026, and gives you a way to work out your own break-even.

The short answer, by business type

Evidence grades used in this guide
A: primary or independent measurement, method stated, Australian scope. Rare on this topic.
B: measured data with a stated method, but vendor-sourced or outside Australia.
C: survey opinion or platform-commissioned research.
D: reasoned guidance from how the platforms work, not measured returns.

If your business is not in the table, three questions usually place it:

1. How long between first contact and a sale? Days point to Meta and search. Months point to LinkedIn and video that builds trust.
2. Are people already searching for what you sell? If yes, search captures that demand and social supports it. If no, social has to create it.
3. Can you produce native video every week? If not, TikTok and YouTube will probably disappoint.

This is reasoned guidance (D). How much of your overall budget should go to social at all is a separate decision, and our guide to allocating digital marketing budgets in 2026 is the place to start. The rest of this guide explains the table.

Why the ROI numbers you have seen contradict each other

Three terms first:

• ROAS (return on ad spend): revenue attributed to ads divided by ad spend. A ROAS of 3.0 (300%) means $3 of revenue per $1 spent. It is revenue, not profit.
• ROI: the gain after costs as a share of costs. It needs a profit figure.
• CPL (cost per lead): ad spend divided by leads. A cost metric, not a return.

Marketer surveys show how unstable “the best platform” is. HubSpot’s 2024 social report named YouTube as delivering the highest ROI.

A September 2025 survey of marketers, charted by Statista from HubSpot data, put Facebook first (54%), then Instagram (43%), YouTube (33%), X (24%) and TikTok (19%). Both are opinions.

The measured ROAS figures disagree for a different reason. Metricool’s report puts Meta Sales campaigns at $4.57 of revenue per dollar in 2026, down from $5.48 in 2025. That figure covers January to June 2026 and is reported by the ad platform.

Dreamdata’s benchmark is built on closed B2B deals and puts Meta at 51%. That is roughly a ninefold gap, and both can be accurate because they measure different things.

The rule that follows: never compare a number from one row with a number from another. A 51% closed-deal ROAS and a 4.57x platform-reported purchase ROAS are different measurements of different businesses, not a ranking. Our guide to why last-click attribution fails service businesses explains why platform-reported figures run generous.

What is different about Australia in 2026

• Money and competition are rising. IAB Australia’s FY26 Internet Advertising Revenue Report shows the market grew 14.0% to $19.8 billion. Social video reached $2.4 billion, up 29.5%. IAB’s CEO said a lot of the new spend is coming from outside the usual base. Our reading: more advertisers competing for the same audiences.
• Reach is not the constraint. DataReportal counted 21.0 million social media user identities in Australia in October 2025, about 77.7% of the population.
• TikTok Shop is not available to local sellers. As of early October 2026 it had not launched, and no date was announced. TikTok’s ANZ lead has said she knew of no launch plans. Purchases happen outside TikTok, so your website and tracking carry the conversion.
• Under-16s are mostly off the major platforms, but not entirely. The rule took effect on 10 December 2025.
  
  • eSafety’s list of age-restricted platforms covers Facebook, Instagram, Snapchat, Threads, TikTok, X, YouTube, Kick and Reddit. LinkedIn is not on it.
  • Platforms face penalties of up to $49.5 million. Preliminary government data says about 4.7 million under-16 accounts were removed or restricted within days.
  • The government does not expect every under-16 to be gone, and eSafety has put five platforms on notice over remaining accounts.
  • Meta says it expects minimal ad impact for most customers. That is Meta’s own claim, and we found no independent measurement.
• Regulators are enforcing advertising rules on social media. See the compliance section below.

The data gap. No public Australian benchmark was found that compares platforms by return with a stated method. This guide does not fill that gap with invented figures. Use the global data to form hypotheses and your own numbers to decide.

Platform by platform: where the return shows up

Meta (Facebook and Instagram)

Best for: retail and e-commerce, local services and clinics, and retargeting for almost any business.

How return shows up: purchases or enquiries within days to weeks.

What the evidence says:

• Survey (C): marketers rate Facebook and Instagram highly.
• Measured, platform-reported (B): Meta Sales campaigns returned $4.57 per dollar in 2026, down from $5.48. Cost per lead rose 14% to $6.00.
• B2B closed deals (B): Meta’s ROAS is 51%, and its cost per company influenced is €128.70 against €70.11 on LinkedIn. That makes Meta weak for winning B2B accounts directly, not necessarily for consumers.

Where it disappoints:

• Low-volume accounts. Meta’s guidance has long cited about 50 optimisation events in seven days to exit its learning phase. A handful of enquiries a week may leave you “learning limited”. Thresholds change, so check the Help Centre.
• Cheap, poor-fit leads (D). Optimising for the lowest cost per lead tends to find form-fillers who never buy. A weak landing page makes it worse, and our landing page playbook for PPC and paid social covers the fixes. Feeding real outcomes back also helps (see the measurement section).

LinkedIn

Best for: B2B services, software and any business that sells to professionals through considered, multi-person decisions.

What the evidence says (B): the 2026 report, drawn from Dreamdata’s B2B customers, shows LinkedIn as the only platform with a positive ROAS, at 121%, against 67% for Google Search and 51% for Meta. As the report frames it, above 100% means revenue exceeded spend. Dreamdata is a LinkedIn Marketing Partner, so read this as a vendor dataset.

Cost is the catch. Dreamdata puts LinkedIn’s CPC at €5.98 and its cost per company influenced at €70.11. The case for LinkedIn rests on counting companies reached rather than clicks.

The lag matters more than the cost. Dreamdata reports buyer journeys of roughly nine months. Those are larger B2B buyers, and a smaller Australian services firm may see shorter cycles. Even so, judging a LinkedIn campaign at 60 days reads the wrong clock.

Where it disappoints: very small target audiences, short sales cycles where search already captures the demand, and businesses that cannot wait months.

TikTok

Best for: consumer brands whose product or service shows well in short video, often with under-35 audiences.

What the evidence says:

• Lead cost (B): TikTok’s cost per lead fell 33% to $2.69, against $6.00 on Meta. Whether those leads buy is a separate question.
• Sales cost, thin sample (B): TikTok’s cost per sale was $1.14 against $11.14 on Meta. But TikTok’s product-sales campaigns shrank to 297 from 1,093, so treat it with care.
• Perception (C): TikTok ranked fifth of five in the 2025 survey (19%).
• Platform research (C): TikTok’s own Dentsu study reports strong returns. It is platform-commissioned.

Australia-specific: with no TikTok Shop, send traffic to your website and plan tracking and landing pages accordingly. Our guide to short-form video and creator content covers formats and creator partnerships.

Where it disappoints: B2B decision-maker targeting is unproven here, so test small. Brands that cannot produce steady native video also tend to struggle (D).

YouTube

Best for: products and services that need explaining, and considered purchases where buyers research before enquiring.

How return shows up: late and indirectly. Viewers often return through search or a direct visit, so last-click reporting undercounts YouTube (D).

What the evidence says (C): YouTube topped HubSpot’s 2024 perceived-ROI ranking and sat third in the 2025 survey. That swing is the lesson: opinion moves, and neither result is a measured return.

Our comparison of short-form and long-form content for Australian service firms helps if you are deciding how much video to make.

Pinterest, Reddit, X and others

We found no Australian return evidence for these that is worth citing. Treat them as small experiments, and only after your core platform works.

Paid versus organic: where organic earns its keep

Paid social buys reach you can measure and control. Organic builds the credibility people check before they enquire. Organic rarely wins on last-click reporting, which is not evidence that it does nothing.

B2B data shows why. In Dreamdata’s 2026 report, LinkedIn company page impressions appeared in 9.4% of marketing qualified leads and 17.9% of closed deals, so organic presence mattered more later in the buying journey. That is one vendor’s B2B data, but it supports treating your profile as a shop window buyers inspect before they get in touch.

Organic is worth funding when:

• Buyers research you before enquiring.
• You have real proof to show: jobs, outcomes and people.
• You want a warm audience to retarget.

Organic is probably not worth it when:

• You expect it to generate trackable leads on its own.
• You cannot post consistently.
• Your buyers decide quickly and find you through search.

To credit organic fairly, add “how did you hear about us?” to every enquiry form and call. If you want help running it, our Content & Engagement team handles organic social management.

Do the maths first

A platform average cannot tell you whether a result is good enough for your business. Your margin can.

Break-even ROAS = 1 ÷ gross margin

Below that ROAS you lose money on every sale. Repeat purchases, management fees and creative costs all move the real answer, so include them. This is arithmetic, not a benchmark.

Example 1: the ROAS that looks good and is not (hypothetical)

A retailer has a 40% gross margin, so break-even is 2.5. The ad platform reports a ROAS of 3.0. If only two-thirds of those sales were genuinely caused by the ads, the real figure is 2.0, below break-even.

Platform ROAS can only be trusted as far as it counts sales the ads actually caused, which is why the measurement section covers holdout tests.

Example 2: the cost per lead that hides a loss (hypothetical)

A local services business spends $4,000 on ads and $2,000 on management and creative in a month, $6,000 in total. Cost per lead is $50, which gives 80 leads. Each job earns $400 gross profit.

The advertising and cost per lead are identical in both columns. What differs is what happens after the enquiry: speed of follow-up, lead quality and sales process. CPL alone never answers the ROI question.

Example 3: the clock in B2B

If your first-impression-to-revenue time is anywhere near the roughly nine months in Dreamdata’s data, closed revenue will not appear for most of a year. Judge early performance on leading indicators:

• Engagement from target accounts.
• Sales conversations started.
• Qualified meetings booked.

Measure without fooling yourself

No single source of truth exists. Use several, and know what each over- or under-states.

Minimum useful setup:

• A conversion event for the real outcome (booked call, quote, purchase), not a page view.
• UTM tags on every ad link.
• A source field in your CRM, filled for every lead.
• A “how did you hear about us?” field on forms and a prompt on calls.
• Outcome data sent back to the ad platform where supported, so it optimises for customers, not form-fills.
• Consent and privacy settings that match your obligations. Our website compliance guide covers the basics.

For a simple holdout, pause a campaign for two weeks, or exclude one region, and compare enquiries with the weeks before. It is crude but far better than trusting a dashboard blindly.

Compliance guardrails that affect your return

This is general information, not legal advice.

• Influencers and reviews. In the ACCC’s sweeps of influencer posts and business reviews, 81% of influencers reviewed made posts that raised concerns, and 37% of businesses had concerning review conduct. The regulator later issued its first financial penalty for undisclosed paid influencer reviews, against PhotobookShop.
  
  • Disclose every commercial relationship, including gifted products.
  • Never write or edit reviews. Our guide to social proof and reviews covers more.
• Health services. Under Ahpra’s testimonial requirements:
  
  • Testimonials cannot be used to advertise a regulated health service.
  • A testimonial is a positive statement about clinical aspects: symptoms, diagnosis or treatment, outcome or skill.
  • A clinic’s promotional Facebook page counts as advertising, and the owner may need to disable reviews.
  • Customer-service comments are not testimonials, but selective editing can mislead.
  • Responsibility sits with whoever controls the advertising, including an agency.
  • The page we read was last reviewed in 2021, so check Ahpra’s advertising hub for updates.
• Under-16 rule. Covered above.
• Finance, legal and insurance. These sectors have their own advertising rules, which this guide does not cover.

A 90-day test plan

1. Calculate break-even. Use the margin formula above and include management and creative costs.
2. Choose at most two platforms from the table at the top. Splitting a small budget across four starves all of them.
3. Define the outcome that matters (booked job, qualified meeting, purchase) and confirm it is tracked before you spend. If leads still live in a spreadsheet, our CRM and retention team can help connect them to your ad data.
4. Size the budget so the algorithm can learn. At a $40 target cost per result and about 50 results a week, that is roughly $286 a day (50 × $40 ÷ 7). If that is out of reach, optimise for a higher-volume event (a lead form, not a sale) and use fewer ad sets.
5. Test creative, not endless audience slices. Change the message, offer or format before you touch targeting.
6. Review on a fixed schedule. These are rules of thumb, not benchmarks:
   
   • Day 30: is tracking trustworthy, did the campaign get enough events, and are leads contacted quickly? Do not judge return yet unless your sales cycle is very short.
   • Day 60 (short-cycle businesses): compare cost per qualified lead or customer with break-even. If it is above, fix the offer, creative or landing page. If it is still above after one round of fixes, stop.
   • Day 90: scale gradually, hold, or stop. For B2B, review on leading indicators and set a 6 to 9 month horizon for revenue.
7. Revisit the budget split once you have real cost per customer data.
