1. Which typical social media channels are there?
In 2025, the following platforms are particularly relevant:
Instagram is an image and video-based platform that belongs to Meta (formerly Facebook Inc.). Users can post photos, videos, stories (content that disappears after 24 hours) and Reels (short videos). The platform is particularly suitable for visual marketing, lifestyle themes, e-commerce and influencer campaigns. Instagram has a very active user population aged about 16 to 40 years.
Tiktok
TikTok is a platform for short videos (usually 15 seconds to 3 minutes), which is mainly used by Generation Z, but is increasingly popular with older target groups. Content is highly algorithm-controlled, which means that even new accounts can quickly gain reach. Particularly relevant for viral campaigns, music, comedy, lifestyle and educative short formats.
Youtube
YouTube is the largest video platform in the world and belongs to Google. It allows you to upload, comment and share videos of different lengths. The platform is suitable for long form content (e.g. tutorials, documentation, reviews), but also for advertising via YouTube ads. YouTube is popular across platforms and offers monetization options.
LinkedIn is a job-related network with a focus on business, career, B2B communication and employer branding. It is often used to share specialist articles, publish company news, recruit employees or position yourself as a specialist expert.
Facebook was one of the first major social media platforms and is now primarily used by older target groups (30+). The platform offers features such as groups, events, marketplace, corporate sites and advertising. Facebook can still be very relevant for local networks, clubs or medium-sized companies.
X (early Twitter)
X is a microblogging service where short messages (up to 280 characters) can be posted. The platform is particularly used in areas such as journalism, politics, technology and activism. Messages and discussions can be followed in real time. The tone is often controversial and content spreads quickly.
Snapchat
Snapchat is particularly popular with younger users. The platform allows you to send images and videos that will automatically delete after viewing. It also offers augmented reality filter and a story function. Snapchat is used more for private communication, but some brands also use it for creative advertising campaigns.
Pinterest is a visual search engine that is used especially for topics such as decorating, recipes, fashion, DIY, wedding and travel. Users store content on so-called “pinboards”. Pinterest has a strong influence on the purchase decision and is often used in the idea generation.

3. Which platforms involve legal risks?
Social media are subject to various legal requirements – especially in German-speaking countries with the GDPR, copyright law, competition law and the Telemedia Act. Here is an overview of the most common risks by platform:
Tiktok
- Privacy: TikTok is repeatedly criticized for its data storage and possible data transfer to Chinese authorities.
- Copyright: Many TikTok videos contain music whose license status is unclear.
- Protection of minors: TikTok is heavily used by children and young people, so strict rules for advertising and data collection apply.
- Advertising marking: Influencers must clearly identify advertising, even for product placements without payment.
- Copyright: The publication of foreign images, quotes or music without consent can lead to cease-and-desist letters.
- Privacy: Integration of Instagram on websites (e.g. through plugins) can be problematic under data protection law.
Youtube
- Copyright: Particularly relevant through the use of protected music, video clips or movie clips.
- Imprint obligation: Channels with a commercial background require an imprint.
- Privacy in comments: YouTube also collects user data via embedded videos on third-party sites.
- Privacy Policy (GDPR): Facebook processes a lot of personal data. The operators of Facebook pages must be jointly responsible for this.
- Imprint obligation: A company page without a correct imprint violates the Telemedia Act.
- Tracking and Analysis: The use of Facebook Pixel on websites is only permitted with the consent of the user.
X (formerly Twitter)
- Hate speech and insults: Users are liable for their statements – criminal content can lead to reports.
- Slander and false statements: Quickly shared content can be legally problematic.
- Privacy: Content will be saved in the long term even if it appears deleted.
- Competition law: Advertising statements on company profiles or employees must be clearly recognizable as such.
- Confidentiality obligations: Professional internals or trade secrets may not be posted publicly.
- Copyright: Specialist articles and shared content should not be accepted without a source or permission.
Snapchat
- Youth protection: The platform harbors risks through short-lived content that can still be stored. Criminal legal consequences are particularly likely with nude pictures or illegal content.
- Privacy: Location releases and face recognition can be problematic in terms of data protection law.
4. General legal pitfalls on social media
Regardless of the platform, the following basic rules apply:
- Observe copyright: Do not use foreign images, music or lyrics without having clarified the rights.
- Protect privacy: Do not publish personal data without consent. A valid data protection declaration must be available on websites.
- Mark advertising clearly: As soon as there is an economic interest (e.g. for product recommendations with affiliate links), this must be declared as advertising.
- Imprint obligation: All commercial profiles or pages require a legally valid imprint.
- Liability for Content: The operator(s) in a profile is liable for all posted content – even for third-party comments if they are not moderated.
- Rules sweepstakes: Sweepstakes must have transparent conditions of participation and be GDPR compliant.
