In brief: with Google Ads, you decide on your own budget. For search ads, you usually pay only when someone clicks. The price of a click depends on competition for the search term, the quality of your ad and your bid. There is no fixed minimum budget. On individual days Google can spend up to twice your daily budget, but over a month no more than 30.4 times that amount.
How does Google Ads charge you?
For search ads, Google Ads mostly works on a pay-per-click basis, or PPC for short. Showing your ad costs nothing. Costs only arise once someone clicks on it. The price of one click is called the cost per click, or CPC.
Other billing models exist as well, depending on the campaign type and bidding strategy. With some display and video campaigns, for example, you pay per thousand impressions or for videos that were watched. If you are starting out with search ads, the cost per click is the figure that matters most.
How much does a click cost on Google Ads?
There is no fixed price. Every time someone searches, an auction takes place. Google compares all ads that qualify for that search term and calculates an Ad Rank for each one. Ad Rank decides whether your ad appears and in which position.
Ad Rank takes several things into account, including:
- Your bid: the maximum amount you are willing to pay for a click
- Ad quality: how well the ad and the landing page match the search
- The context of the search: for example location, device and time of day
The actual cost per click is often lower than your maximum bid, because you only pay what is needed to keep your position. To get a rough idea of click prices in your industry, look at the free Keyword Planner inside Google Ads. Its figures are estimates and vary by region and time period.
What drives the cost?
Competition
The more businesses bid on the same search term, the more expensive the click becomes. Terms linked to high revenue, such as insurance, legal advice or finance, tend to be especially pricey.
Quality Score
Google rates your keywords with a Quality Score on a scale from 1 to 10. It is made up of three parts: expected click-through rate, ad relevance and landing page experience. A high Quality Score can help you reach better positions at lower cost.
Region and timing
Competition in large cities is often stiffer than in rural areas. Time of day and season play a part too, for instance in retail in the run-up to Christmas.
Keyword match types
Match types let you set how closely a search has to match your keyword. Broad options bring more clicks, along with more irrelevant ones. Exact options are more targeted. Negative keywords stop your ad from showing for searches that do not fit your business, such as "free" or "job".
How does the daily budget work?
For each campaign you set an average daily budget. Google is allowed to spend more on some days to take advantage of good opportunities. According to Google Ads Help (as of October 2026), two limits apply:
- On any single day, at most twice the average daily budget.
- Over a month, at most 30.4 times the average daily budget.
An example: with a daily budget of 20 euros, Google can spend up to 40 euros on one day. Over the month, though, you will not pay more than 608 euros (20 × 30.4). If Google delivers more clicks than that, the amount above this limit is not charged.
How do I work out a sensible budget?
Work backwards from your goal. You need three figures:
- Estimated cost per click: from the Keyword Planner
- Expected conversion rate: how many visitors send an enquiry or buy. If you do not know this yet, measure it during the first few weeks.
- Value of an enquiry or sale: what a new customer brings you on average
A worked example with assumed figures: a click costs 2 euros, and one in every fifty visitors gets in touch. That puts the cost of an enquiry at around 100 euros. Whether this pays off depends on how many enquiries turn into orders and what an order is worth. Always plug your own numbers into this calculation.
What costs come on top of the clicks?
- Time for management: campaigns need regular attention. If you run them yourself, count your own time.
- Agency or freelancer: many charge a fixed monthly fee or a share of the ad budget.
- Landing page: a good landing page can noticeably lower the cost per enquiry, but someone has to build it first.
The Google Ads account itself is free of charge. You only pay for the advertising.
How do I lower the cost per enquiry?
- Use negative keywords and check the search terms report regularly.
- Write ads that match the search closely.
- Send clicks to the subpage that fits the search, and keep them away from your home page.
- Set up conversion tracking so you can see which keywords bring in enquiries.
- Limit your ads to the regions and times in which you can actually serve customers.
Common mistakes
- Launching a campaign without conversion tracking
- Relying on broad keywords only and never maintaining negative keywords
- Accepting automatic recommendations without checking them
- Judging the budget after a few days, before enough data has come in
Google Ads or SEO?
Google Ads gives you visibility straight away, and that visibility stops as soon as you stop paying. SEO takes longer, and its effect lasts. Many businesses combine the two: ads for quick results and for testing keywords, SEO for building up reach over the long term. You can read more on our PPC Management topic page.
