Which social media is better?
I don't use Facebook (don't have an account now) For promoting a website, Facebook does a good job. As they have huge audience and their promotion service is very efficient.
I use twitter now and i didn't find the effectiveness as Facebook, so for promotion and advertisement Facebook does a great job.
Instagram, without doubts. Also, if you're popular, you can become an influencer. If you're interested, here you can read about who they are and how to become one 🙂
But isn't Instagram just pics and videos with basic commenting? How is this "better" than FB?
