Google Ads vs Meta Ads: Which Delivers Better ROI for Aussie Businesses?

Which paid channel deserves the bulk of your Australian marketing budget in 2025 — Google Ads or Meta Ads?

Google Ads: high-intent capture

People searching "emergency plumber Melbourne" have their credit card ready. Google Ads is perfect for capturing that in-market demand. Average AU CPCs range from $2 (info queries) to $25+ (legal, finance).

Meta Ads: interest-based discovery

Facebook and Instagram excel at introducing your brand to people who don't yet know they want you. AU CPMs are around $8-$20 depending on industry.

Industry benchmarks (Australian data)

  • Trades & home services: Google wins 3:1
  • Ecommerce fashion: Meta wins 2:1
  • B2B services: Google + LinkedIn wins
  • Local hospitality: Meta wins for awareness, Google for bookings
  • Wellness & fitness: Meta wins for lead-gen funnels

The best answer? Both, at the right ratio

Most SiteHarbour clients run a 60/40 or 40/60 split between the two. Google captures demand; Meta creates it.
