How to Choose a Marketing Agency in Germany: Questions, Pricing Models and Warning Signs

How do you choose a marketing agency?

Define your goal first, shortlist three to five agencies and ask every one the same written questions. Then compare the answers on goals, measurement, account access, reporting, contract terms and the person who will do the work. The price comes last, because it only means something once the scope is equal.

1. Write down the goal in business terms, such as enquiries, bookings or orders, and the period you have in mind.
2. Shortlist agencies from referrals, directories and search, and read their own websites critically.
3. Send each the same brief and the same questions.
4. Speak to the person who would work on your account, as well as to the sales contact.
5. Check references and live work that you can open yourself.
6. Compare written offers by scope, reporting and exit terms, then by fee.

The sections below cover the questions, the pricing models, ownership, reporting and the warning signs.

Which questions should you ask a marketing agency?

Ask questions that have answers you can check later. The table lists eight topics, a question for each and what a useful answer contains.

How do marketing agencies charge?

Agencies charge in four main ways: a monthly retainer, a project fee, a performance-based fee or an hourly rate. Advertising spend is usually a separate cost, because it is paid to the advertising platform. Each model has strengths and weaknesses, and the right choice depends on how clear your scope is.

What a marketing agency costs in Germany depends on the scope, the channels and how much senior time you need. A single average figure says little, because the scopes behind it differ. Ask for written offers for the same brief and compare them line by line.

The offer should show the fee and the ad budget as two separate lines. We work that way at Digital030, and our usual recommendation for performance marketing is an ad budget of at least €500 to €1,000 a month, and more in competitive sectors such as solar or property. We do not publish fixed prices for our own work. A quote follows a free 30-minute call, once we know your goals.

Who should own the accounts and the data?

Your business should own every account the agency works in, and the agency should be given access to them. Then you keep your campaigns, their history and your data if the work ends.

• Advertising accounts such as Google Ads and Meta Ads.
• Analytics and Google Search Console for your website.
• Your domain name and hosting.
• Social media profiles and business listings, including your Google Business Profile.
• E-mail marketing and CRM tools that hold customer data.

The Google Ads help pages show how this works for advertising accounts. An agency can link its manager account to your account, and users on your side with administrative access can end that link at any time. A manager account can also be made the owner of a client account, so check in the account settings who is listed as owner before you approve the set-up (Google Ads Help, about manager accounts).

Give each person their own login with the access level the task needs, and do not send a shared password by e-mail. Ask for a written handover plan that says which logins, files and documents you receive at the end and how quickly.

What should a marketing agency report to you?

A report should show results in your terms: enquiries, bookings or orders, where they came from and what they cost. Clicks, impressions and follower counts are only useful when they connect to those results.

• Enquiries and, where known, customers won, split by source.
• Cost per enquiry and cost per customer, with fee and ad spend shown separately.
• What the agency did this month and what it plans for the next.
• Problems and open decisions, such as a page that loses visitors or a keyword that wastes budget.
• Data you can export, so that the report does not stay locked in the agency’s own portal.

Ask for a sample report before you sign, and ask for a monthly call to discuss it. A report that you cannot explain to a colleague is not doing its job.

Which warning signs should make you pause?

Pause when an agency promises results it cannot control, hides how it works or makes it hard for you to leave. Google lists several of these in its own advice on hiring an SEO, and they apply to marketing agencies in general (Google Search Central, hiring an SEO).

• Promises of a top ranking, or a claim of a special relationship with Google. Google states that no one can promise a first-place ranking.
• A firm that will not explain clearly what it will do. Google lists secretive companies among its warning signs.
• Unsolicited e-mails that offer services. Google advises treating unsolicited SEO offers with the same scepticism as other scams.
• No access for you to your own accounts, or an agency that holds the only login.
• Reports full of impressions, reach and clicks with no enquiries or sales.
• Fee and ad budget mixed into one figure, so that you cannot see what is spent where.
• A long minimum term with no stated way out, or pressure to sign this week.
• Case studies with no named client, no time frame and no description of how the result was measured.
• Nobody named as responsible for your account.

How do you check references and case studies?

Open the live work, talk to a former client and ask how each result was measured. A case study is a claim until you can verify the basics.

1. Visit the client’s website on a phone and on a computer. Does it load quickly, and is it clear what to do next?
2. Ask for a contact at a client whom you can call, in a similar sector or with a similar goal. Google suggests asking past clients whether the SEO was useful, easy to work with and delivered good results, and the same questions suit any agency.
3. Ask what the result measured, over which period and what else changed in that time, such as a new price, a season or a new product.
4. Ask who did the work. The person in the case study should be the person on your account, or a clearly described team.
5. Check the agency’s own website and Google profile. An agency that sells websites should have a site that loads well on a phone.

Results do not transfer automatically. A good result in one sector shows how the agency works and does not predict your numbers. A careful agency will say so itself.

Agency, freelancer or in-house hire?

An agency fits when you need several skills and a team that can cover absence. A freelancer fits a defined task in one channel. An in-house hire fits when there is enough continuous work for a full role. Many companies combine the options.

Do language and time zone matter?

Language matters most for German-language copy and for how well you can follow what the agency does. Time zone matters less. Germany follows Central European Time, so check when the team is available and plan calls around it.

• Who writes the German copy? Ask whether a native German speaker writes or reviews it.
• In which language are calls, reports and contracts? An agency that speaks English may still send contracts and invoices in German, so ask for an English summary if you need one.
• Does the team know German search habits and local platforms? Ask for examples from German-language projects.
• How quickly does the team reply, and on which days is it reachable?

How useful are agency directories?

Directories help you build a shortlist, and they should not make the decision for you. They collect profiles, service lists and reviews in one place, which saves time at the start.

Before you rely on one, check three things. Who writes the profile? How are reviews verified? Does the listing order depend on payment? Each directory explains this differently, so read its own description. Treat what you find as a starting point and verify it with the agency’s references and your own conversation.

Platform badges and partner levels also have their own criteria. Ask what the criteria are and whether they say anything about results in a client’s account.

Is it worth hiring a marketing agency?

It is worth it when the extra customers or revenue are larger than the agency fee plus the ad budget, and when you can measure that. It is not worth it when you cannot say what a new customer is worth, when you have no capacity to answer enquiries or when the offer or the website is not ready.

A simple test is to divide the monthly fee by the profit from one new customer. The result is the number of extra customers per month that the agency must bring to cover its fee. The numbers in this example are invented to show the arithmetic. They are not typical figures and not prices.
