You can, but we suggest you don't. Different groups of people are located on different social media platforms and require different approach. Use high-quality visual content for Instagram. It is good to use a mix of everything on Facebook - text posts, photos, videos...  Speak in a business tone and post professional content on LinkedIn. TikTok is great for short and fun videos. For X (former Twitter), write short texts that quickly get the point across. YouTube, on the other hand, requires quality videos that have added value (educate and/or entertain).
