Definition: Logos simply explained

A logo is a graphic symbol, text, or a combination of both. It represents a company, an organization, a brand, a person, or a product. It embodies the brand’s entire visual identity and makes it recognizable at a glance.

Important: A good logo is distinctive. It’s easy to remember. It works in every situation—whether on a business card, in an app, at a trade show booth, or on social media.

Logo, Signet, Brand, Corporate Identity?

Logo: A graphic or typographic symbol that represents the brand or company.

Signet: The graphic element of the logo, often a symbol without text.

Brand: The overall image of a company or product. It encompasses not only the logo, but also values, promises, and the customer experience.

Claim: A short, concise phrase accompanying the logo that succinctly captures the brand promise or corporate philosophy. It is often permanently associated with the logo.

Slogan: A catchy advertising message typically used in connection with a specific campaign. A slogan is more flexible and, unlike a claim, is changed more frequently.

Corporate Design (CD): Corporate design is a company’s comprehensive design system. It includes the logo, colors, typography, and other design elements.

Corporate Identity (CI): The identity (in the sense of personality) of the company. It encompasses the company’s values, self-image, and communication.

What types of logos are there?

There are various types of logos. A logo typically consists of a wordmark or a combination of a wordmark and a figurative mark.

1. Logotype: The logo consists of lettering.

2. Signet/Symbol: The logo is a graphic symbol.

3. Wordmark/Figurative Mark: A combination of an image and lettering.

Word Marks (Company Logos)

Here, the company name or a product name is presented typographically.

Examples: Visa, Coca-Cola

Advantages:

• Memorable, especially for short, distinctive names
• Immediately understandable, since it’s easy to read

Disadvantages:

• Less flexible than an icon or favicon
• Doesn’t work well if the name is too long or complicated

Figurative Marks (Logo Symbols)

Minimal, memorable graphic forms make up the main component of the logo. These symbols alone represent the entire brand.

Examples: Apple, Twitter

Advantages:

• Very versatile (e.g., as an app icon or social media profile)
• Often particularly memorable and universally understood

Disadvantages:

• Difficult to remember without accompanying text at the beginning
• Risk of confusion if the design is too abstract

Figurative marks/logos can be further classified according to the following criteria:

Illustrative figurative marks

Here, the design elements or graphic symbols can be clearly associated with a specific offering. They symbolically represent certain products or services.

Examples: Burger King, Tchibo

Advantages:

• You can highlight the company’s activities

Abstract figurative marks

The logo’s shape does not directly indicate what the brand offers. This type of logo works well when the product or service is difficult to represent because it cannot be touched or seen. Even if the product or service range is very broad and cannot be easily represented by a single shape, this type of logo is a good fit.

Examples: LEGO, Nestlé

Mascot

Mascots are illustrative, often highly stylized depictions of characters (people, animals, etc.).

Examples: KFC, Haribo (bear)

Advantages:

• Very emotional, creates a sense of closeness and personality
• Particularly well-suited for family or children’s products

Disadvantages:

• May come across as unprofessional in the B2B sector
• Often difficult to implement as a favicon or small icon

Abstract Logos

These designs use abstract, graphic shapes that are easy to grasp. They often convey a certain feeling rather than a specific image.

Examples: BP, Pepsi

Advantages:

• High degree of creative freedom, very modern
• Well-suited for companies with a wide range of offerings

Disadvantages:

• Little association with products/services
• Rarely self-explanatory

A logo acts like a beacon: Amid the visual clutter created by your competitors, it draws attention to your company. Often, a single glance is enough to understand what your brand stands for – provided the logo is clear, distinctive, and strategically designed.

The logo is an essential part of a company’s visual identity. It shapes the first impression of a company or brand. A good logo is essential for a professional image. A logo establishes the first connection between a company and its target audience.

Logos Attract Attention

A logo makes a company, an organization, or a product or service recognizable and memorable. Through consistent and systematic use, it builds trust and fosters a sense of identification among customers, partners, and employees.

Your company will be found quickly and will stick in people’s minds.

Logos Convey Uniqueness

A logo shapes the first impression of a company. It is a key component of corporate design and leaves a unique impression.

In a competitive market, a unique logo makes all the difference.

Logos evoke emotions

A successful company logo represents a company’s values, goals, and philosophy. It conveys abstract messages at a glance and visualizes what defines the company. It appeals to the target audience and creates a connection between the company and its target audience.

Logos Provide Orientation

A well-designed logo provides orientation and clearly sets your brand apart from the competition. A professional logo ensures high brand recognition.

It offers your target audience a clear point of reference—and also helps employees identify with the brand.

• Trust & Professionalism: A good logo conveys competence and reliability.
• Orientation: It provides your target audience with a clear point of reference and helps employees identify with the brand.
• Conveying a Message: The logo serves as a platform for your brand’s core values.

A well-designed logo contributes to your overall brand design and is often the starting point for a successful corporate identity.

Platform solutions or generic do-it-yourself logos are inexpensive. But a truly effective logo can only be created through collaboration with experts—and will pay off for many years to come.

Does your logo meet all the basic requirements? If not, it’s time for a logo redesign.

What Does the Future Hold?

The Logo in the Digital Age – Trends and the Future

Today, we see logos everywhere—on smartphones, websites, in apps, and on social media. They are often animated or adapt to different sizes.

Especially on websites – which are now the most important communication channel for companies—the logo must be easy to use without losing its impact and message across different resolutions (on different devices).

In the past, it was very important for colors to look exactly the same in print. Today, that’s less important. That’s because we don’t know what color settings users have on their computers or cell phones. On the other hand, logo animations can be created and optimized for all environments or channels (responsive logos).

When it comes to the future of logo design, scalability and animation are more important than color accuracy and pixel-perfect dimensions.

Good logo design is simple and meets the requirements for scalability, simplicity, and versatility. Today, this is more important than color accuracy or elaborate details.

A professionally designed logo remains the cornerstone of your visual identity – across every channel, at all times.

Conclusion

A logo is the most important visual element of your brand. Choosing a professional approach means investing in brand recognition, trust, and long-term business success.
