Google Ads management in Australia typically costs $800-$3,000+/month in agency fees. On top of that, you'll need an ad spend budget - most Australian SMEs run $1,500-$10,000/month in actual spend. The right numbers depend on your industry, how competitive your keywords are, and what you're expecting in return.
Why the price range is so wide
That $800-$3,000+ range exists because Google Ads management isn't one thing. A local tradie running a single service-area campaign is a very different engagement from a national eCommerce brand managing thousands of product ads across multiple campaigns.
Here's what typically drives the price:
- •Account complexity - number of campaigns, ad groups, and keywords being actively managed
- •Industry competition - legal, finance, and real estate keywords can cost $20-$100+ per click
- •Ad spend volume - most agencies charge more when managing higher budgets
- •Service depth - some retainers include landing page work, conversion tracking setup, and monthly strategy; others are just keeping the lights on
- •Reporting and communication - weekly check-ins and detailed reports take real time
What's included in a proper Google Ads retainer?
Pricing varies because what's included varies. A proper retainer should cover:
- •Campaign setup or restructure (if starting fresh)
- •Keyword research and negative keyword management
- •Bid management and budget allocation
- •Ad copy writing and A/B testing
- •Conversion tracking setup and verification
- •Monthly performance reporting with actual insights
- •Strategic recommendations based on your data
What it shouldn't include: vague "optimisations", recycled monthly reports that restate the obvious, or an account manager who has never actually run an ad themselves.
How much should I budget for ad spend?
Your management fee and your ad spend are separate things. Ad spend is what you pay Google - it goes directly to clicks. For Australian SMEs, here's a rough guide by goal:
- •Testing whether Google Ads works for your business: $1,000-$2,000/month for 60-90 days
- •Generating a consistent lead flow for a local service business: $2,000-$5,000/month
- •Scaling a national campaign or eCommerce store: $5,000-$20,000+/month
One thing worth knowing
There's no point spending $5,000/month in ad spend if your landing page converts at 1%. The budget and the strategy need to be calibrated together. Good management includes identifying when this is the problem.
Flat fee vs percentage of spend - which is better?
Some agencies charge a flat monthly retainer. Others charge a percentage of ad spend, usually 10-20%. Both models have trade-offs.
Flat fee: predictable cost, and the agency doesn't benefit from inflating your budget. Percentage of spend: the agency is incentivised to grow your spend, which is sometimes aligned with your goals and sometimes not.
At Buttercup, we charge a flat monthly fee with no percentage component. Your budget decisions should be yours.
How to tell if an agency is worth the cost
The management fee is only good value if the returns exceed it. A few things to look for:
- •They track conversions properly - not just clicks and impressions
- •They can tell you your cost per lead (CPL) or cost per acquisition (CPA) clearly
- •You own the Google Ads account - not them
- •They're transparent about what they're doing and why
- •Their recommendations make commercial sense, not just marketing sense
If an agency can't explain your CPL or CPA in the first conversation, that's a meaningful red flag.
