The advantages of a good agency briefing

Clear communication & target definition

A good agency briefing ensures clear communication and prevents misunderstandings, as all project goals, expectations and requirements (e.g. budget) are clearly set out.

Efficient collaboration & resource planning

It enables structured and efficient collaboration, saves time and resources and facilitates the planning of processes, budgets and deadlines.

Understanding of brand & target group

The agency gains a deep understanding of the company, its target group and brand values, which promotes the development of tailor-made, creative solutions.

Get to know us - personally, reliably and fairly.

Why is it worth investing time in a good agency briefing?

Yes, creating a comprehensive briefing can be time-consuming. However, good preparation not only ensures that misunderstandings are avoided and everyone involved shares the same expectations, but also gives you as a company a much clearer idea of the desired collaboration, the relevant marketing channels and the most important KPIs. During the briefing process, internal questions are clarified and goals are specified - this not only helps the agency, but also your own team to make strategic decisions with confidence and make the success of the project measurable. A well thought-out briefing is therefore a win-win situation for both sides and forms the basis for efficient, creative and targeted collaboration.

What are the most common internal problems in companies?

Unclear or missing target definitions

Strategic goals, target groups and expectations are not clearly defined.

Lack of internal coordination

Important departments and stakeholders are not sufficiently involved.

Time pressure & insufficient preparation

The briefing is prepared hastily and superficially and too late.

Too vague or unstructured information

Requirements are imprecise or contain too many irrelevant details.

Incomplete background information

Important data on the company, market and previous measures are missing.

Lack of written documentation

Briefings are often only communicated verbally, which makes traceability difficult.

When does it make sense to rebrief an agency?

Especially if you have already had bad experiences with agencies, feel overwhelmed in the briefing process or see opportunities to increase efficiency, a rebriefing can be decisive for the success of the project. A rebriefing always makes sense if requirements have changed or the previous results do not meet your expectations.

In these situations, a new agency briefing makes sense:

  • Unclear requirements: If you have the feeling that the agency has not understood your request correctly or misunderstandings arise, a rebriefing helps to create clarity and bring everyone involved up to the same level.
  • Changed goals or framework conditions: If your goals, priorities or the market environment change during the course of the project, a rebriefing is necessary to adjust the strategy and measures.
  • Feedback &

Frequently asked questions about the agency briefing

What information do I need to provide the agency so that they understand my project?

Provide a clear project description, background information about your company, your target audience, the desired outcomes, your budget and the timeframe. If there is any information you are unsure about, please state this exactly as it stands. Agencies often find it helpful to have rough estimates to get a sense of the project’s scope. However, a good agency will always offer advice during a meeting to address your questions and concerns. After all, it is not solely your responsibility to develop a coherent marketing concept from the information provided.

How do I clearly articulate my goals and expectations?

Use the SMART criteria (Specific, Measurable, Achievable, Relevant, Time-bound) to define your goals precisely and transparently. An agency can assist you in specifying these criteria, as they often bring experience and benchmark data from similar projects and are trained in interpreting target audiences, data anomalies and trends.

Who exactly is my target audience and how do I best describe them?

Describe your target audience based on demographic characteristics, interests, needs and, where applicable, behaviours. In e-commerce, purchasing power and device type are also particularly relevant. Your agency will always ask for further information if anything is missing.

How much budget and time should I set aside?

Please provide a realistic budget range and a rough timeline so that the agency can plan accordingly. Here too, a range (e.g. from–to) is helpful if you don’t yet have specific figures.

Which channels, media or measures make the most sense for my objective?

Don’t worry – you don’t have to decide this on your own. It helps if you give some thought in advance to which marketing channels are best for reaching your target audience – though this isn’t a must. You can look forward to the advice and recommendations of your advertising agency here.

How do I deal with missing or uncertain information?

The key here is transparency. Be open about where uncertainties lie and ask the agency for help in clarifying or researching them. If, for example, you are unable to estimate the ad spend at all, it can also be helpful to deliberately seek recommendations from the Google Ads agency rather than ruling out options from the outset.

How do I prevent misunderstandings and ensure that the agency implements my requirements correctly?

Formulate your requirements as specifically as possible and necessary, set out all key points in writing, and schedule regular meetings. However, remain open to your agency’s input – after all, they are just as interested in the project’s success and achieving the communication goals as you are.
