Social Media Trends in South Holland

Short-form video remains the dominant format across platforms. Brands that create authentic, entertaining and informative videos consistently outperform those relying on static images. Behind-the-scenes content, tutorials and employee stories are particularly effective.

Influencer and creator marketing continues to grow, with micro-influencers delivering strong engagement within local communities. Rotterdam and The Hague have vibrant creator scenes covering food, fashion, lifestyle and sustainability.

LinkedIn is increasingly important for business-to-business companies in South Holland, particularly in sectors such as logistics, maritime, energy, technology and government services. Thought leadership content and employer branding campaigns help attract clients and talent.

Social commerce is also rising, with shoppable posts and in-app purchasing making it easier for consumers to buy directly from social platforms. Meanwhile, privacy regulations and changes to tracking have made first-party data and creative quality more important than ever.

How to Choose a Social Media Agency

Begin by defining your objectives. Are you seeking brand awareness, community engagement, lead generation or direct sales? Different agencies specialise in different areas, from creative content to performance advertising or influencer management.

Review case studies and ask about results achieved for similar businesses. Consider whether the agency understands Dutch audiences and local culture, including language nuances and regional differences. Transparent reporting, clear pricing and regular communication are essential for a successful partnership.

Building an In-House and Agency Partnership

Many South Holland businesses now use a hybrid model, keeping day-to-day posting and community management in-house while relying on agencies for strategy, paid campaigns, video production and influencer partnerships. This approach keeps the brand voice authentic and responsive while giving access to specialist expertise and advanced tools. Clear brand guidelines, a shared content calendar and regular performance reviews help both sides work together effectively and ensure every post supports wider business goals.

Final Thoughts

Social media offers enormous opportunities for businesses in South Holland, but success requires expertise, creativity and consistent effort. Whether you partner with a full-service agency like DEPT, a video specialist like Dutch Rose Media, an influencer expert like IMA or use insight tools like Coosto and Buzzcapture, the right support can help your brand stand out and build lasting relationships with customers.
