How much does Google Ads cost for a small business?

In the US a search-ad click cost a median $5.42 (€4.65) in the year to March 2026, across 13,474 campaigns. The UK average for 2025 was £2.01 (€2.34), and Bulgarian agencies put a local-service click at €0.50 to €2.50 from their own accounts. What a small business pays is that price times the clicks it takes to win customers, plus any management fee.

Google has no price list. You set an average daily budget, and a Search campaign charges only when somebody clicks (Google Ads Help). Google counts a month as 30.4 days, so €30 a day is a monthly ceiling of €912 (budget help).

Published starting budgets land between €500 and about €2,500 a month of media: €500 to €1,000 from a German agency and a Bulgarian one, £750 to £1,500 (€870 to €1,750) from a UK agency for a local business with little competition, and $1,000 to $2,500 (€860 to €2,150) for an American small business, or up to $3,000 (€2,570) at one US agency.

The fee comes on top.

Every search is an auction. Google ranks the competing ads by Ad Rank, which combines your bid with its judgement of how useful your ad and landing page are, the expected effect of extras such as a phone number, and the context of the search (how the auction works). Each advertiser then pays just enough to clear Google's minimum and beat the ad ranked below (actual cost per click).

With nobody beneath you, you pay a reserve price. Places above the results demand a higher minimum Ad Rank, so the same keyword costs more at the top of the page.

Quality Score, the 1-to-10 grade next to each keyword, is easy to misread. It rates expected click-through rate, ad relevance and landing page experience against advertisers on the same search over the last 90 days, and Google calls it a diagnostic tool, not an input in the ad auction. The auction makes its own quality estimate, and a relevant ad can take a higher position at a lower price than a rival bidding more. A landing page rated “Below average” is the cheapest fix in the account.

A 2026 benchmark of US search campaigns runs from a median $1.63 (€1.40) a click for arts and entertainment to $9.87 (€8.47) for lawyers. UK clicks cost less: hundreds of UK campaigns averaged £2.01 in 2025, up 17% on £1.72 a year earlier, with prices rising in 71% of industries. Bulgarian clicks cost less again.

A UK agency's 2026 price guide puts plumbers and other local trades at £0.50 to £3 a click (€0.58 to €3.49), dentists and solicitors at £4 to £15 (€4.66 to €17.46), and personal injury law and finance at £15 to £50 or more.

In Bulgaria, one agency's own campaigns over the past year put repairs and salons at €0.50 to €2.50 a click, and a second agency, from its work with clients, gives €0.50 to €1.50 for repairs and €1.80 to €3.50 for lawyers. Fewer businesses bid on each Bulgarian search, and none can bid more than a customer is worth to it, in a country whose consumer prices were the lowest in the EU in 2025: 63% of the average (Eurostat).

The US benchmark's first edition, in 2016, put the average click at $2.32 and the average lead at $59.18. Ten years on, the click costs more than twice as much and the lead about 13% more, while the average conversion rate has gone from 2.70% to 8.18%. More clicks now turn into enquiries, and the landing page is the part of that you control.

Your own price will differ.

It comes from Keyword Planner inside a Google Ads account, which asks for billing details before it shows keyword ideas (Use Keyword Planner). Enter your searches and the towns you serve, and read “Top of page bid (low range)” and “Top of page bid (high range)”: roughly the 20th and 80th percentiles of what advertisers paid for the top of the page over the last 30 days (Keyword Planner forecasts).

Start from the enquiries you want. Divide them by your expected conversion rate to get the clicks you need, then multiply by the cost per click Keyword Planner shows for your searches and area. At US benchmark rates, 20 enquiries a month cost from about $560 (€480) for a car repair shop to $3,560 (€3,050) for a law firm.

Swap in your own numbers when you have them. For the cost per click I use the high end of Keyword Planner's range in the first month, because Google's notes on its forecasts give two reasons for caution: a new advertiser's forecast is built from the average of all advertisers, and a small area makes any forecast less accurate. Health and finance searches often show no figures at all (Use Keyword Planner), and there the table above is all you have. The conversion rate is harder. Use your site's own rate if you know it, or the benchmark for your category until 30 days of real traffic replace it.

Then test it against what a customer is worth. If one enquiry in three becomes a customer who leaves €600 of margin, an enquiry can cost up to €200 before the campaign loses money. The dental row, at about $75 (€64) an enquiry, passes easily; the legal row, at $178 (€153), needs a client worth more than about €460.

If the answer is more than you want to spend, shrink the campaign rather than the bids: one service, the postcodes you cover, the hours somebody answers the phone. Twenty clicks a week spread across ten services teaches you nothing about any of them.

For a small business I start with a Search campaign: text ads on searches you choose, a report of the searches you paid for, and keywords you can exclude. Performance Max spends one budget across YouTube, Display, Search, Discover, Gmail and Maps, and Google presents it as a complement to keyword-based Search campaigns (About Performance Max).

Performance Max bids towards your conversion goals, so until the account records enquiries it has nothing to steer by, and a €900 month spread over six channels leaves little for any one of them to learn from. Google's newer AI Max setting brings broad matching and Google-chosen landing pages into Search campaigns (About AI Max). I leave it off until the account has a month of clean conversion data.

Performance Max offers negative keywords, brand exclusions and channel reports, including a search terms report. Compare it with Search using tracked enquiries, lead quality and acquisition cost for the same business.

Without conversion tracking, Google Ads counts clicks, not customers, and Smart Bidding strategies such as Maximize Conversions have nothing to bid towards (conversion measurement). Add the Google tag or import key events from Google Analytics 4, and watch a test conversion reach the account before the campaign goes live. On the campaigns we run, nothing launches until it has.

Imported key events can take 24 to 48 hours to appear, so start a few days before launch, and mark only the actions you would pay for as primary.

Calls deserve their own line. Google can count calls from the ad through a forwarding number, calls to the number on your site and taps on that number from a phone, and for a plumber or a dental practice an account that counts only forms is steering by a fraction of its enquiries. Forwarding numbers work in 30 countries, the UK, the US, Germany, France, Spain and Poland among them, but not in the Netherlands, Austria or Bulgaria (Google forwarding numbers). There Google counts only the taps, so a number that appears nowhere but the landing page, checked against the phone company's call log, shows how many people rang.

For visitors in the European Economic Area, the UK and Switzerland, Google's EU user consent policy requires their consent to cookies where the law demands it and to the use of their data for ad personalisation. Consent mode passes that choice to the tag and lets Google model the conversions it cannot see (About consent mode), so part of the count in Google Ads is an estimate.

Managing a Google Ads account costs 10% to 20% of the ad spend or a flat monthly fee, and neither includes the clicks. Published flat fees run from £400 to £1,500 (€470 to €1,750) or more a month at UK agencies and from $1,000 to $3,000 (€860 to €2,570) at American ones; one US agency charges a flat $1,000 (€860) a month for accounts spending up to $1,500.

By the hour, an agency directory's PPC pricing page, updated on 10 September 2026, lists $100 to $149 (€86 to €128) for American PPC agencies and $50 to $99 (€43 to €85) for those in the UK, Poland and Spain. In Bulgaria, one agency's price list starts at €205 a month, plus €275 once to set up a single Search campaign.

Below about €2,000 a month of spend I would pay a flat fee. A percentage grows with the spend rather than the work, and 15% of €1,000 is €150, under four hours of work at those UK hourly rates. Whatever the model, ask whose name the ad account is in, whether call tracking is part of the set-up, how often somebody reads the search terms, and who changes the landing page when the numbers point at it. We quote Google Ads management once we have seen the landing page and the goal, and the ad account stays in your company's name.

Budgets leak through defaults nobody changed and things nobody counted: broad match keywords with no negatives, search partner sites, location settings that include people interested in your area, phone calls the account never sees, and ads that send every click to the home page.

Broad match is the default for every new keyword, and Google calls it critical to pair broad match with Smart Bidding (keyword matching). A new account has no conversions to bid on, so I start with phrase and exact match and add negatives such as jobs, salary, course, training and DIY on day one; negatives ignore close variants, so plurals and synonyms go in separately (negative keywords).

Search partners, the other websites and YouTube pages that show Google search ads, are switched on by default, and Google does not tell you which partner site showed your ad (Search Network). I launch without them. Location targeting defaults to “Presence or Interest”, which Google illustrates with a Paris bakery whose ads reach people interested in Paris bakeries (location options): right for a bakery tourists look up, wrong for a plumber. A plumber wants “Presence”.

The home page is the wrong destination for nearly every ad. Someone who searched for dental implants should land on a page about implants, since landing page experience is one of the three parts of Quality Score. The site we rebuilt for Amir Hair Clinic, a dermatology practice for hair loss, has a treatments page that explains each treatment in turn and a short questionnaire to open the conversation: a page that answers the search, and a first step small enough to count as a conversion.

Expect a noisy first month. A new campaign has no history, and Google describes a standard 7 to 14 day learning phase for Smart Bidding that restarts whenever budgets, targets or conversion goals change (conversion measurement). Judge those 30 days by the searches you paid for and whether the tracked enquiries were real people; cost per enquiry comes later.

Full calibration takes longer: Google says a bid strategy can need up to around 50 conversions, or three conversion cycles, to settle (learning period), and at 20 enquiries a month that is two and a half months. In week one I read the search terms report, which leaves out searches too rare to show, and add negatives. At the end of week two the conversions in Google Ads go next to the calls, forms and emails that actually arrived; if they disagree, the tracking is wrong and so is every figure built on it. On day 30 the cost per enquiry meets the ceiling from the worksheet, and that decides whether the budget grows.
