Communication agency – all you need to know

A communication agency is a company that plans and coordinates internal and/or external communication on behalf of its clients.

Internal communication aims to unite employees around the company’s objectives. Examples include websites, intranets, corporate wikis, etc.

External communication aims to promote the company’s image to the target audience. Examples include websites, social networks, promotional pamphlets, web advertising, etc.

In this article, we will answer why, how, who, and when to use a communication agency, as well as explore the different types of communication agencies.

Types of Communication Agencies

There are essentially two main types of communication agencies:

  1. Full-Service Communication Agencies or 360° Communication Agencies:

These agencies advise their clients on both internal and external communication. They also handle advertising and direct marketing for the companies they work with.

The Roles of a Communication Agency:

A communication agency assists and advises its clients in promoting their image to the target audience (customers, prospects, partners, suppliers). Its main tasks include:

  • Assisting the client in developing their communication strategy.
  • Enhancing the client’s image and increasing its visibility.
  • Implementing communication actions targeting the intended audience.
  • Offering effective communication mediums and techniques in minimal time.

Why Use a Communication Agency?

To attract a new audience, retain customers, develop relationships between the company and employees, and more, strategic communication consulting is essential!

Using a communication agency allows you to:

  • Benefit from expert advice with a guarantee of results.
  • Enjoy guidance and follow-up for your communication activities.
  • Save time and money.

How to Choose a Communication Agency?

Before selecting a communication agency, it is essential to determine your needs (SEO, print communication, AdWords advertising, communication campaigns, etc.) and create a project brief.

Based on your project brief, you can choose an agency by considering the following factors:


Price is an important criterion but should not be the sole consideration. Opting for the lowest price may lead to ineffective results, resulting in a waste of time and money. The ideal choice is an agency that offers the most relevant solution to your problem.


Depending on your needs, expertise may also be essential. To assess this, engage with the agencies you are considering and evaluate how relevant their advice and solutions are for your business.

A good tip is to compare the offerings of a generalist agency with those of a specialized agency to determine if you need a high level of expertise.

A social media marketing agency may help businesses by providing case studies that demonstrate the effectiveness of their marketing campaign. Because if the agency can help other customers effectively, it surely can help you too.


Quotes and services offered do not always provide a complete picture of the quality of service. It is recommended to visit the websites and social media profiles of agencies to analyze their references and view past work.
