I recently had an account hit 100,000 followers so I decided to take a look into the analytics to see what I've been doing right and what I've been doing wrong. Over the past month the account has reached over 2,500,000 people on Twitter. The average engagement rate for a tweet without an image is 1-3%. The average engagement rate for a tweet WITH an image is 24%+! I've always had the mindset of mixing my content and I've enjoyed posting text status updates because that's what I've always done, but I will definitely be including an image in my 2-3 tweets daily across all of my accounts from this point forward. Anyone else noticed this on their accounts?
