There is no single right number for a Google Ads budget, because it depends on what a click costs in your industry and how many customers you need. That sounds vague, but it is not: you can work out a sensible budget from a few simple pieces. Here is how to set a Google Ads budget that actually produces leads, instead of guessing.
How Google Ads billing actually works
Before you pick a number, understand what you are buying. Google Ads runs on a pay per click auction: you set the maximum you are willing to pay for a click, you only pay when someone actually clicks, and Google confirms you control a daily budget you can change at any time. Your bid is not the only factor either, because a more relevant ad can win a better spot at a lower cost. This matters for budgeting, because a well built campaign stretches the same dollars further.
The math behind a budget
Work backwards from a customer. Say a click in your industry costs $4, and one in twenty clicks becomes an enquiry, and one in three enquiries becomes a customer. That is sixty clicks, or about $240, per customer. If a customer is worth far more than that to you, the campaign makes sense, and your monthly budget is simply how many customers you want times that cost. The numbers vary by industry, but the method is always the same: cost per click, then clicks to leads, then leads to customers.
What moves your cost per click
Industry and competition
Competitive fields like legal or trades cost more per click than niche services. More bidders means higher prices.
Keywords
Broad, high demand terms cost more than specific ones. Choosing the right keywords is one of the biggest levers on cost.
Quality and relevance
Google rewards relevant ads and landing pages with lower costs and better positions. A sloppy campaign literally pays more.
Location and timing
Targeting the right areas and hours keeps you from paying for clicks that will never convert.
A realistic starting budget
For most small Montreal businesses, a meaningful Google Ads test starts in the range of a few hundred to a couple of thousand dollars a month, enough to gather real data without being wasted on too little. Spending too little is the classic mistake, because a tiny budget never collects enough clicks to learn what works. If you are also weighing the organic side, our guide on SEO versus Google Ads covers how the two fit together.
Frequently asked questions
Can I start small and scale?
Yes, and you should. Start with enough to gather data, learn what converts, then scale the winners. Just avoid starting so small that you never get a clear signal.
Why is my cost per click so high?
Usually competition, broad keywords or low ad relevance. Tightening your keywords and improving your ads and landing page often brings the cost down.
How fast will I see leads?
Ads can bring clicks the same day. Turning those clicks into a reliable flow of leads usually takes a few weeks of tuning.
Should I do SEO at the same time?
Often yes. Ads deliver leads now while SEO builds free traffic that lowers your reliance on paid clicks over time.
