I think a lot of people are using facebook, twitter, and instagram. Whatsapp is famous in my country, and snapchat is also gaining some popularity.
Instagram is definitely the most social media be used. Instagram is so versatile and can be used to not only express oneself, but it can also be used as to make money, advertise/sponsor, spread awareness on current events, and to create an identity for oneself.
#1 Facebook. #2 Depends on what your industry is, some are better for certain demographics, again however Facebook is a clear #1.
depends on what are your goals, but most powerful for businesses are Facebook and Instagram, if you are in corporate life than LinkdIn, if you are a video creator than TikTok, quite easy there to gain a lot of views and grow organically.
Everyone knows that Facebook, Twitter, and Instagram are the most common and popular social networks. What stupid question you have posted.
Tik tok is not such a professional social network. Facebook Twitter and Instagram are very popular and common.
