Google Ads pricing: how much a campaign costs

A click on Google Ads costs €4.70 on average, but in some industries it exceeds €9 and in others it stays below €2. Anyone considering investing in online advertising almost always faces the same question: what are Google Ads prices really like for a business like mine?

There’s no single answer, because the cost depends on the industry, the competition and the goal of the campaign. People asking how much it costs to advertise on Google often think only about the individual click, but the sums need doing on the whole monthly investment. In this guide we look at how Google Ads prices are formed, how much businesses invest on average by goal (lead generation, e-commerce, brand awareness) and how to keep cost per click down without giving up results.

How Google Ads costs work

Google Ads has no fixed price list. It works through a real-time auction between the businesses that want to appear for the same keywords: every time someone searches on Google, that auction decides which ad appears and how much the click will cost.

The cost per click (CPC) you pay depends on three factors:

• the maximum bid you set for that keyword
• the Quality Score Google assigns based on ad relevance, landing page quality and the likelihood of a click
• the level of competition for the same search, meaning how many businesses are targeting the same keywords

For the same bid, a relevant ad linked to a well-crafted landing page can cost less than a poorly built one: Google rewards the quality of the campaign, not just the budget on the table. That’s why Google Ads prices vary even between two businesses in the same industry, depending on how the campaign is set up. The cost of a Google Ads campaign worked out at the end of the month depends on this too: it isn’t enough to look at the starting CPC; what counts is how the campaign is managed over time. The technical details of the auction and billing system are explained in Google Ads’ official guide to costs and payments.

Average cost by industry: Google Ads prices compared

Google Ads prices vary considerably from one industry to another, because they reflect the value of a customer and the intensity of advertising competition. A lawyer or financial adviser can afford a higher CPC because a single new client is worth thousands of euros. Businesses selling low-margin products, on the other hand, need to keep cost per click lower and go for volume.

The following table shows average CPCs by broad industry and an indicative monthly budget for launching a campaign with enough data to optimise it (around 300 clicks a month as a baseline).

Industry	Indicative average CPC	Indicative monthly budget to get started
Law firms and professional services	€7 – 10	€2,000 – 3,000
Financial and insurance services	€5 – 8	€1,500 – 2,400
Dentists and medical clinics	€6 – 9	€1,800 – 2,700
Renovations and home services	€6 – 9	€1,800 – 2,700
Personal services and wellbeing	€4 – 7	€1,200 – 2,100
B2B and business services	€4 – 6	€1,200 – 1,800
Fashion and retail e-commerce	€3 – 5	€900 – 1,500
Restaurants and food	€1.50 – 3	€450 – 900

Recommended minimum budget to get started

There’s no budget threshold that applies to everyone. The useful minimum depends on the campaign’s goal, the CPC in your industry and the time you’re willing to devote to optimisation. As a rule of thumb, to get out of the learning phase of automated bidding algorithms you need at least 15-20 conversions a month per campaign: below that threshold the system struggles to learn and results remain erratic.

Before setting a figure, it’s worth understanding how Google Ads prices change depending on what you want to achieve.

Lead generation (professional practices, tradespeople, local B2B)

Goal: contact forms, quote requests, phone calls. For a local business with an average industry CPC of around €6-7, a budget of €800-1,500 a month is a realistic starting point.

Example: a dental practice with an average CPC of €7 aiming for 20 quote requests a month, with a landing page conversion rate of 10-15%, needs to plan for around 150-200 clicks a month. The corresponding budget is roughly €1,000 to €1,400.

E-commerce

Goal: direct sales through Shopping or Performance Max. Here the useful minimum budget is higher, indicatively €1,500-3,000 a month, because these formats need more conversions for the bidding algorithm to work well. Here too, Google Ads prices on their own don’t say much unless you read them alongside your product margin.

Budget alone isn’t enough: a fashion e-commerce business with an average CPC of €4 and a ROAS target of 400% must first check its margin per product, or it risks generating traffic that’s never truly profitable.

Brand awareness

Goal: visibility and recognition, not immediate conversions. On Display and YouTube, cost is more often measured in CPM (cost per thousand impressions) than CPC, with indicative budgets of €1,000 to €2,500 a month.

Brand awareness shouldn’t be judged by the same metrics as lead generation: the reference metrics are reach, frequency and brand recall, not the number of forms completed. If the goal is multichannel awareness, it’s worth comparing Google Ads prices with those of other platforms: our dedicated pages explain the costs and formats of Facebook Ads, Instagram Ads, LinkedIn Ads and TikTok Ads.

Checklist: what to check about Google Ads prices before you start

• A clearly defined campaign goal: leads, sales or awareness
• The average CPC in your industry checked, not estimated by eye
• Conversion tracking switched on and tested before launch
• A landing page that’s ready to convert, not merely published online
• A budget large enough to get through the algorithm’s learning phase
• Optimisation time planned in: at least 2-3 months before judging the results

How to lower your CPC without losing results

Lowering cost per click doesn’t mean cutting the budget, but spending what you’ve already allocated more effectively.

Quality Score remains the most effective lever: relevant ads and fast landing pages consistent with the user’s search can reduce the CPC you pay for the same ad rank. It’s also worth reviewing keyword match types, preferring more targeted matches to broad match left unchecked, and adding negative keywords to exclude searches that will never lead to a conversion.

Geotargeting and ad scheduling matter as much as keywords: concentrating budget where and when the campaign converts best avoids paying for clicks that will never become a real lead. Remarketing also helps keep average spend down: reaching people who have already visited the site generally costs less than reaching a completely cold audience, as we explain in our guide to remarketing on Google Ads.

Finally, testing several ad variants within the same ad lets the algorithm identify the most efficient combination over time. Google explains the different bidding strategies available in its official guide to choosing your bid and budget, which is useful for understanding which approach best suits your goal.

In short

Google Ads prices aren’t a fixed number: they depend on the industry, the quality of the campaign and the goal you want to achieve, whether that’s generating leads, selling online or building awareness. The table and budget examples in this guide are a starting point to help you get your bearings, not a promise of results.

FAQ

What do Google Ads prices really look like for an SME?

It depends on the industry: from €1.50-3 per click for restaurants and food to €7-10 for law firms. The table in this guide shows average ranges and an indicative monthly budget to get started.

What do Google Ads prices depend on?

Three factors: the bid you set, the Quality Score of the ad and landing page, and the level of competition for the chosen keyword.

Is it worth starting with a small budget?

Yes, but with realistic expectations: with a budget that’s too small compared with the industry CPC, the campaign collects little data and struggles to optimise. It’s better to start with a budget in line with the table in this guide, even if it’s lower than the average.

Can I set a maximum spending cap?

Yes, you can set a daily budget that Google won’t exceed on a monthly average. This lets you keep control of your Google Ads costs with no surprises on the invoice.

Are Google Ads prices the same in every industry?

No. As the table shows, the average CPC can vary by 5-6 times between a low-competition industry and a highly competitive one such as legal or financial services.

How long does it take to see results?

Generally 2-3 months, the time it takes for the algorithm to collect enough conversion data and for the campaign to settle.

Why do two similar businesses pay different Google Ads prices?

Because the Quality Score of the ad and landing page affects CPC as much as the bid you set. Within the same industry, whoever looks after campaign relevance better often pays less for the same result.
