These days, being a social media expert takes more than just knowing how to write eye-catching captions and building a brand. No, you also need to know how to connect with your audience on an almost daily basis. Looking good and/or professional isn’t enough. You also need to be socially aware of what is happening in different communities. One crucial step in this process is to know when and how to celebrate national social media holidays that raise awareness about a certain cause. Which is why I am sharing the most complete list with over 220+ national and international social media holidays in October with you!
