Emerging and niche platforms

• Threads (Meta): A fast-growing microblogging alternative to X (formerly Twitter) with strong integration with Instagram.
• WhatsApp: Primarily a direct messaging app, but WhatsApp Business can be used for automated customer service, updates, and promotions with very high open rates.
• Pinterest: Functions as a visual search and discovery engine, making it ideal for e-commerce, especially for home décor, fashion, and DIY niches.
• Reddit: Niche, topic-based communities ("subreddits") allow for authentic, hyper-targeted engagement and market research if approached with a community-first mindset.
• X (formerly Twitter): Best for real-time updates, news, and brand awareness in trending topics. 

Top marketing trends influencing all platforms

• Video is everything: Short-form vertical video (Reels, TikToks, Shorts) generates the highest engagement. Ensure your content is mobile-first, authentic, and includes captions for accessibility.
• AI-powered personalization: Artificial intelligence is being used for hyper-personalization, from ad targeting to automated content creation and chatbot customer service.
• Social commerce: Platforms are becoming full-fledged marketplaces with in-app shopping features, shoppable posts, and live shopping events.
• Rise of micro-influencers: Brands are shifting from mega-influencers to micro- and nano-influencers who have smaller but more engaged and trustworthy communities.
• Authenticity and community: In an age of AI-generated content, consumers crave authentic, human stories and a sense of belonging. Invest in community building and user-generated content.
