Meta + Google Ads Together: How Australian SMEs Should Think About the Mix

What each channel actually does

The fundamental difference: Google Ads is intent-based. Someone searches "emergency plumber Perth" because they have a burst pipe. Meta is interruption-based. Someone is scrolling Instagram and sees an ad for a service they didn't know they wanted yet.

Practical consequences:

• •Google converts faster - the buying intent is already there
• •Meta builds demand and brand recognition over time
• •Google CPCs scale linearly with competition; Meta scales with creative quality
• •Google rewards account structure and bid management; Meta rewards creative volume
• •Google attribution is cleaner (gclid, last click); Meta attribution is murkier (longer view-through windows)

How to figure out where to start

Three diagnostic questions:

1. Is there existing search demand for what you sell?

Use Google Keyword Planner to check. If "[your service] [your city]" has hundreds of monthly searches, start with Google - the demand is already there to capture. If almost no one is searching for what you sell, Google can't help you yet. You need Meta to create the demand first.

2. Is your product visual or considered?

Furniture, fashion, fitness, food, beauty, weddings, anything visual - Meta excels because the creative does the selling. Legal services, finance, plumbing emergencies, B2B SaaS - Google excels because the user knows what they want and is searching for it.

3. Is your sales cycle short or long?

Short cycle (immediate purchase or enquiry) suits Google. Long cycle with multiple touchpoints suits Meta supporting Google - Meta builds familiarity over weeks, Google catches the eventual searcher.

When both channels compound

The case for running both is when they reinforce each other. We see this clearly in branded search lift - when a Meta campaign runs hard, brand searches on Google rise 30-60% within 2-3 weeks. The Meta ad introduced the brand; the Google search closed the deal.

The mirror is also true: customers searching commercial queries on Google often retarget through Meta in the following days, leading to the actual conversion on a Meta click. Last-click attribution makes Meta look uninvolved when it was crucial.

How to split budget

There's no universal split. Working rules for Australian SMEs:

• •New brand, no search demand yet - 80% Meta, 20% Google (brand defence + non-brand commercial)
• •Established brand with search demand - 60% Google, 40% Meta (Google captures, Meta amplifies)
• •Local service business with steady search demand - 80% Google, 20% Meta (test creative for awareness)
• •eCommerce with strong product imagery - 50/50 or 40/60 toward Meta if creative is strong

Below $3,000/month total paid budget, picking one channel and doing it well usually outperforms splitting. The attention tax of running both isn't trivial - separate creative, separate measurement, separate optimisation cycles.

The attribution trap

Both platforms report conversions through their own lens. Meta sees the conversion that touched a Meta ad. Google sees the one that touched a Google ad. Counted together, you'll see roughly 130-160% of your actual conversions - both platforms taking credit for shared journeys.

The fix is to anchor decisions in your CRM or backend revenue, not platform reports. If total paid spend is $X and closed revenue from paid is $Y, that's the only ROAS that matters. Use platform reports for relative comparison, not absolute truth.

When NOT to add a second channel

• •Your first channel isn't profitable yet - fix that before splitting attention
• •You don't have the creative capacity for Meta - one new video every 6 weeks won't cut it
• •Your total budget is under $3,000/month - sub-scale on both channels is worse than scale on one
• •You can't answer "what is the current job-to-be-done for this channel?" for each one
