Quick answer: You can run Google Ads on $500 a month if you focus on one service, a few high-intent keywords and a tight area, and track every lead.
Google Ads can work on a small budget, but only if you’re realistic and very focused. Here’s how to give $500 a month (about $16 a day) the best chance.
Do the maths first
At $4 per click, $500 buys about 125 clicks a month. If 1 in 10 visitors enquires, that’s around 12 enquiries. If clicks in your industry cost $10, it’s 50 clicks and maybe 5 enquiries. That’s still workable if each customer is valuable, but there isn’t much room for waste.
Use Keyword Planner to check typical bids for your keywords and area before you start. Remember Google adds 10% GST for Australian accounts.
Rules for a small budget
- One Search campaign. Skip Display, YouTube and Performance Max for now.
- Your one or two most profitable services only.
- Tight keywords: exact and phrase match on high-intent searches such as “emergency electrician Wollongong” rather than broad terms like “electrician”.
- A strong negative keyword list from day one. Read negative keywords.
- Tight location and schedule. Read location settings that waste money.
- A focused landing page for that service. Read landing page checklist.
- Conversion tracking working before you spend a dollar.
Bidding on a small budget
With few conversions, Smart Bidding has little data. Many small accounts start with Maximise clicks with a maximum CPC limit, or Manual CPC, then move to Maximise conversions once conversions build up. If you use Maximise conversions from the start, keep your keywords tight so it can’t wander.
What results to expect
Expect a slower start. With fewer clicks, it takes longer to see patterns, so judge over at least four to eight weeks. Measure cost per enquiry and jobs won, not clicks.
When $500 isn’t enough
If your cost per click is high (legal, finance, some trades) or you need lots of leads, $500 may only buy a handful of clicks. In that case consider Local Services Ads if eligible, a narrower service area, a higher budget for a short test, or Meta ads alongside. Read how much should a small business spend on Facebook ads?
