There's no universal number — the right budget depends on how much competition you're bidding against and how much a single customer is worth to your business.
What drives your Google Ads budget
- Cost per click in your industry. Legal, finance and emergency trades can see clicks cost $10–$50+, while lower-competition local services often pay $1–$5 per click.
- Customer lifetime value. A business where one customer is worth thousands can justify a higher cost per lead than a low-margin, one-off service.
- Geographic targeting. Targeting all of Sydney costs more than targeting a handful of suburbs, simply due to search volume and competition.
- How fast you want results. Larger budgets generate data faster, which shortens the time it takes to find what converts.
Typical monthly budgets by business type
| Business type | Typical monthly ad spend |
|---|---|
| Local trade or home service | $1,000–$3,000 |
| Professional services (accounting, consulting) | $2,000–$5,000 |
| Legal, finance or medical | $4,000–$10,000+ |
| eCommerce | $2,000–$15,000+ |
Ad spend vs. management fees — what's the difference
Your ad spend goes directly to Google as a bidding budget — it's separate from what you pay an agency or freelancer to build, manage and optimise the campaigns. A $2,000/month plan might mean $1,500 in ad spend and $500 in management, or the two might be quoted separately. Always ask a provider to break this down clearly before signing on.
Signs your budget is too low
- Your ads rarely show for your main keywords, even during business hours
- You're spending most of the budget on broad, low-intent searches instead of high-intent ones
- You get clicks but too few conversions to draw any real conclusions each month
Bottom line
Start with at least $1,500–$2,000/month in ad spend if you're in a competitive Sydney market — enough to gather meaningful data within 4–6 weeks. Below that, campaigns often move too slowly to optimise properly. The best next step is a strategist reviewing your specific keywords and competition, since the right number for a plumber in Parramatta looks nothing like the right number for a CBD law firm.
