Google Ads agency costs: Which pricing model is fair?

Google Ads agencies usually charge in one of three ways: a fixed monthly fee, a percentage of your ad spend, or a mix that includes a performance-based share. Percentages of roughly 10 to 20 percent of ad spend are common in the market, often with a minimum fee. The fair model is the one where the agency benefits from you getting more enquiries, not from you spending more.

The three pricing models compared

Fixed fee. A set amount per month for a defined scope of work. Advantage: predictable, and the agency has no incentive to inflate your budget. Disadvantage: if the account grows significantly, the scope has to be renegotiated.

Percentage of ad spend. The fee rises with your budget. Advantage: it reflects the extra work that large accounts require. Disadvantage: the agency earns more when you spend more, even if the extra spend delivers nothing. Make sure there is a clear cap.

Performance-based. Part of the fee depends on enquiries or revenue. It sounds ideal, but it requires reliable tracking and a clear definition of “success”. Otherwise you end up arguing about the numbers.

Costs on top of the fee

• Setup: account analysis, tracking, campaign build. Often charged once.
• Landing pages: usually not included in ongoing management.
• Creative assets: images and videos for Display, YouTube or Performance Max.
• Tools: some agencies pass on software costs.

You pay the ad spend itself directly to Google. Do not agree to the agency running your budget through its own invoices without you seeing the Google invoices.

What to look for in the contract

1. The Google Ads account is registered to your company. The agency has access, not ownership.
2. The term and notice period are short, around three months.
3. The scope is specific: how often is the account optimised, how often do you get a report, who is your contact?
4. Reporting shows cost per enquiry or revenue, not just clicks.
5. If you cancel, campaigns, data and tracking stay with you.

How to compare offers

Do not compare the fee, compare the total cost per enquiry. An agency that costs 300 euros more per month but eliminates 800 euros of wasted spend is the cheaper one. So before signing, ask for a short analysis of your existing account.

FAQ

Is a Google Ads agency worth it with a small ad budget?

It depends on how large the fee is relative to the budget. If management eats up a large share of your total spend, too little is left for clicks and the agency cannot achieve much. In that case, a one-off setup with occasional check-ins can make more sense than ongoing management.

How much does Google Ads itself cost, apart from the agency?

With Search campaigns you usually pay per click, and the price is set in an auction against other advertisers. Google does not require a minimum budget; you set your daily budget yourself. How expensive a click is depends heavily on your industry, region and competition.

Is a certified Google Partner agency more expensive?

Not necessarily. Google Partner status is free for agencies and tied to requirements such as ad spend, account performance and staff certifications. It shows that the agency has proven experience with Google Ads, but it says nothing about its pricing model.

When to hand this over

• You pay an agency but do not know what you get for it.
• The fee rises with the budget, but the enquiries do not.
• You manage the account yourself and are losing track.
