Google Ads in Europe: costs, consent rules and multi-country campaigns

Running Google Ads in Europe works like anywhere else, with three differences that change your results and your bill. First, costs vary widely by country, and Google adds surcharges of 2% to 5% for ads shown in some countries, such as Austria, France, Italy, Spain and the UK. Second, for visitors in the EEA, the UK and Switzerland you need valid consent before ad cookies are used, passed to Google through consent mode, or your conversion tracking and remarketing shrink. Third, multi-country campaigns need a deliberate structure by country and language, because Google's language targeting is changing and a single "Europe" campaign rarely spends well. Here is how each part works.

What Google Ads costs in Europe

Cost per click varies by country and industry

There is no reliable public table of average cost per click by European country. Published figures are usually limited to one industry, one month or a vendor's own clients. The only dependable number is the one for your own keywords, in your own markets.

Use Keyword Planner in Google Ads for that. For each keyword it shows a low and high range for top-of-page bids: roughly the 20th and 80th percentiles of what advertisers paid recently for that position, based on your location and network settings. Run it separately for each country and language you plan to target. You will typically find that the same commercial keyword costs much more in the UK, Germany or the Netherlands than in Greece, Portugal or Poland, but there are exceptions, especially in niches with few local competitors.

Surcharges by country

Google adds a percentage to the cost of ads served in some countries to cover digital services taxes and other regulatory costs. They are charged on top of your budget, appear as separate lines on your invoice, and VAT applies on top of them. Current rates for Europe, according to Google's help page:

The surcharge depends on where the ad is shown, not where your business is. With location targeting set to "presence or interest", ads can reach people in countries you didn't select directly, and those impressions can carry a surcharge too.

VAT on Google Ads

Advertisers in the EU are billed by Google Ireland. Businesses in Ireland are charged Irish VAT. Businesses registered for VAT in another EU country don't have VAT added by Google and account for it themselves at their own country's rate, so make sure your VAT number is entered in the billing settings. The "purpose of use" you choose at sign-up (business or non-business) is permanent and decides how VAT is applied.

Currency and time zone are permanent

An account's currency and time zone can't be changed after set-up. If you want to be billed in euros, Swiss francs and pounds separately, you need separate accounts under a manager account. Decide before you create the account.

Consent rules for advertisers

What Google requires

Google's EU user consent policy applies to users in the EEA, the UK and Switzerland. If you use Google's advertising products, you must obtain valid consent for cookies or local storage where the law requires it, and for the use of personal data for ad personalisation. You also have to keep records of consent and tell users how to withdraw it. Google can limit or suspend accounts that don't comply.

The European Union's Digital Markets Act adds pressure from the other side. Alphabet was designated a gatekeeper in September 2023, with its search and online advertising services among the covered platforms, and gatekeepers may not track users across services for targeted advertising without effective consent.

Consent mode in plain terms

Consent mode is how your website tells Google tags what the visitor agreed to. It doesn't create the cookie banner; you still need a consent management platform (CMP) for that. In November 2023 Google added two signals to it:

• aduserdata: whether the visitor agreed to their data being sent to Google for advertising;
• ad_personalization: whether they agreed to personalised advertising, such as remarketing.

Both must be granted for personalised advertising. If adpersonalization is denied, remarketing lists don't receive that visitor. If aduser_data is denied, conversion data tied to that visitor is limited.

Basic or advanced consent mode

• Basic: Google tags don't load until the visitor makes a choice. If they refuse, nothing at all is sent. Google estimates missing conversions with a general model.
• Advanced: tags load straight away with consent set to "denied" by default, and send cookieless signals while consent is denied. Google can then estimate missing conversions with a model specific to your account.

Advanced mode gives better conversion estimates. Basic mode sends less data. Which one fits depends on your legal advice and your country's regulator; some regulators take a stricter view of any data sent before consent. Whichever you choose, consent mode results show only after at least seven full days.

Do you need a Google-certified CMP?

Publishers who earn money from AdSense, Ad Manager or AdMob must use a Google-certified CMP to serve personalised ads in the EEA, the UK and Switzerland. Advertisers are not required to. Google's CMP partner programme states that nothing prevents advertisers from using a non-partner CMP. A certified CMP does make the consent mode integration easier, so it's often the practical choice.

Political ads

If your business touches politics, note that Google announced in November 2024 that it would stop serving political advertising in the EU before the EU's regulation on political advertising took effect in October 2025.

Structuring multi-country campaigns

One campaign per country, at least

Separate campaigns per country let you set a budget, bids and ad schedule that fit each market's costs and time zone. A single campaign targeting ten countries tends to spend most of its budget in the cheapest or busiest one, which may not be where your customers are.

Language: what's changing

Google decides language based on signals such as the language of the search and the user's language settings. Starting in September 2026, Google is removing the campaign-level language setting for Search campaigns: search ads now match based on the language of the ads themselves. In Performance Max, the language setting no longer applies to ads on the Search Network. Google says no action is needed, but it means the language you write in decides who sees your ads, so:

• write keywords and ads in the language people actually search in;
• in multilingual countries such as Belgium or Switzerland, consider separate campaigns per language with the same location;
• send each ad to a landing page in the same language.

Translation

Google offers an AI tool, in beta, that creates a localised copy of an English (US) Search campaign in languages including French, German, Dutch, Italian, Polish, Portuguese and Spanish, translating ads, targeting and even landing pages. It's useful as a starting point. Have a native speaker review the result before launch: literal translations often miss the words people actually type, and a keyword that's cheap in one language may be expensive in another.

Location settings

"Presence or interest" is Google's default and recommended setting. For a local service business, "presence" (people in or regularly in the area) is usually the safer choice, because it keeps clicks from people who only showed interest in your area from elsewhere.

Landing pages and tracking per country

Each country version should have local contact details, prices in the right currency, and the legal pages that country expects. Set up conversion tracking with consent mode before you spend. Compare countries on cost per lead or cost per sale, not cost per click.

A short launch checklist

1. Research keywords and bids per country in Keyword Planner.
2. Budget for country surcharges and VAT.
3. Install a CMP and consent mode v2, then test refusing and accepting.
4. Build one campaign per country (or per country and language).
5. Write ads and landing pages natively in each language.
6. Set location targeting deliberately, not by default.
7. Review results per country after four to six weeks.
