What does it actually cost to advertise on Google?

If you've ever looked into Google Ads and quietly decided it was probably too expensive, you're not alone. It's one of the most common reasons small businesses rule it out before they've looked into it properly. The assumption is that it's something bigger businesses do, with bigger budgets, and that there's no point even considering it unless you're prepared to spend serious money.

That assumption is worth questioning.

You control what you spend

The first thing worth knowing is that you set the budget. Google doesn't decide how much you spend — you do. You choose a daily limit, and once that limit is reached, your ads stop showing for the day. You're not going to log in one morning to find you've accidentally spent thousands overnight.

You can also pause your campaigns at any time. If things go quiet in your business and you want to stop spending for a while, you can. There's no contract, no minimum term, no penalty for pressing pause.

That makes it more controllable than most people expect.

You only pay when someone clicks

Google Ads works on a pay-per-click basis. That means if your ad appears in search results but nobody clicks on it, you don't pay anything. You pay when someone actually visits your website as a result of the ad.

What you pay per click depends on what you're advertising and how many other businesses are bidding for the same searches. Some industries are more competitive than others. A solicitor in central London is going to pay more per click than a dog groomer in a small market town. But for most local service businesses, the cost per click is more reasonable than people assume.

What a realistic budget actually looks like

There's no single right answer here, because it depends on your industry, your location, and what you're trying to achieve. But the principle is this: a modest monthly budget, spent well on the right searches, can generate real enquiries. A larger budget spent poorly will generate very little.

The budget is one variable. How the account is set up — which searches trigger your ads, which don't, what the ads say, where they send people — has just as much influence on whether you get results.

This is why two businesses can spend the same amount and have very different outcomes.

The question worth asking

The real cost question isn't "how much does it cost to advertise on Google?" It's "what would one new client be worth to my business?"

If a new client is worth £500, and a well-run campaign brings in two or three new enquiries a month on a modest budget, the numbers start to look quite different. It stops being a question of whether you can afford to advertise, and becomes a question of whether you can afford not to.

That's not a case for spending money you don't have. It's a prompt to think about it as an investment rather than a cost.

Getting it right matters

Google Ads can work well for local service businesses. It can also burn through a budget quickly if the setup isn't right — wrong targeting, the wrong settings left switched on, no way of tracking whether any of it is actually generating enquiries.

The cost of advertising on Google is one thing. The cost of doing it badly is another.

If you're curious whether it could work for your business, it's worth having a proper conversation before you spend anything. That's exactly what I'm here for.
