How much do Google Ads cost? What sets the price and how to budget
How much Google Ads costs: how the auction prices a click, why costs vary so much by industry, how to look up your own costs and set a starting budget.

Google Ads has no fixed price. You pay for each click, the cost of a click is set by an auction every time someone searches, and the result can be pennies for some searches and tens of pounds for others. Your total cost is the budget you choose, so the real question is how much budget your searches need to produce a readable result, and that comes from your cost per click and how many clicks it takes to win a customer.
What decides the cost of a click
- Competition: how many advertisers want the same search and what a customer is worth to them.
- Quality Score: Google's 1 to 10 rating of your expected click-through rate, ad relevance and landing page experience. Higher quality can win the same position for less.
- Position: appearing at the very top costs more than appearing lower down.
- Location, device and time: the same search can cost more in a city centre, on mobile, or at peak hours.
- Bidding strategy: automated bidding sets bids per auction within the target or budget you give it.
You never pay more than your maximum bid, and usually less: the price depends on what is needed to beat the advertiser below you, given both your quality.
Why costs vary so much between industries
Advertisers bid roughly what a click is worth to them. Where one customer is worth thousands, such as legal, financial and B2B services, clicks are expensive. Where a customer is worth a few pounds, they are cheap. For example, in Google's Keyword Planner for the UK, the top-of-page bid range for "ppc agency bristol" was about €18 to €96 per click in our own research for this site, because agencies compete for clients worth a great deal. A search for a low-cost consumer product would typically be a small fraction of that.
Keyword Planner showed our figures in euros because of the account's currency setting. The ranges are a guide to what advertisers bid for the top of the page, not a promise of what you will pay.
How to look up your own costs
- 01Open Keyword PlannerInside Google Ads, under Tools. It is free to use with an account.
- 02Enter your searchesThe services or products you sell, as customers would type them, with your town if you are local.
- 03Set the locationThe area you serve, not the whole country, because prices differ by place.
- 04Read the bid rangesThe low and high top-of-page bid columns give a realistic range for appearing at the top.
Setting a starting budget
Work backwards from the result you need. If a typical click costs about £3, around 1 in 20 clicks becomes an enquiry, and 1 in 3 enquiries becomes a customer, then each customer takes about 60 clicks, or £180 of ad spend. If a customer is worth more than that, the campaign can be profitable; if not, the numbers need to change before the budget does. Our PPC calculator runs this sum for your own figures.
A useful rule for a first test is a budget large enough to buy a few hundred clicks on your main searches over the first month or two. Fewer than that and the results are too thin to tell a good campaign from a lucky week.
The other costs
- Management: the time to run the account, whether yours or an agency's. See how our fees work.
- Landing pages: a page that converts well lowers every other cost, and may need building.
- Tracking: setting up conversion tracking properly is a one-off job that makes every later decision possible.
Ways to pay less for the same result
Improve Quality Score through relevant ads and better landing pages, block search terms that never convert, set location and schedule to when and where customers actually buy, and move budget to the campaigns producing the cheapest qualified results. Most of the savings in a typical account come from removing waste rather than bidding cleverly.
What a monthly budget buys: three worked examples
These are illustrations of the arithmetic, not figures from any account. Swap in your own cost per click and conversion rate from Keyword Planner and your website.
| Business type | Assumed cost per click | Monthly budget | Clicks | Enquiries at 5% |
|---|---|---|---|---|
| Local trade | £2.50 | £1,000 | 400 | 20 |
| Professional service | £6.00 | £1,500 | 250 | 12 or 13 |
| Online shop | £0.60 | £1,000 | about 1,670 | about 83 orders |
The table shows why cost per click alone tells you little. The professional service gets far fewer enquiries for more money, and can still be the most profitable of the three if each client is worth thousands.

Questions on this topic
Is there a minimum spend for Google Ads?
Google sets no minimum budget. In practice, a budget too small to buy a few hundred clicks over a month or two gives too little data to judge whether the campaign works.
Do I pay Google or the agency for clicks?
With most agencies, including us, you pay Google directly for the clicks and the agency separately for management, so you always see what was spent on ads.
Why is my cost per click so high?
Usually high competition for your searches, a low Quality Score, or bidding for the very top position. Better landing pages and tighter keyword targeting are the most reliable fixes.
How much should a small business spend on Google Ads?
Enough for a readable number of clicks on its main searches each month. Multiply the typical cost per click from Keyword Planner by the clicks you need to win a few customers.
Can I set a daily limit?
Yes. Each campaign has an average daily budget. Google can spend up to twice that on a busy day and less on quiet ones, but it will not charge more in a month than the daily average multiplied by 30.4, the average number of days in a month.
