If there is one thing everyone can agree on, it's the fact that people enjoy images. Probably more so than videos, images naturally grab our attention. They're instantly recognizable and it takes just a second to share them with our friends — which is why it's crucial brands use them as often as possible.
Did you know that tweets containing images get 2x the engagement than tweets without images? It's a fascinating stat that should not go unnoticed.
Doubling your engagement rate not only increases the probably of receiving more retweets and favorites, but your followers count will begin to build quicker than it normally would.
Now you have to ask yourself, why not use an image in every tweet? There's really no reason not to, especially considering Twitter displays images inline via the traditional web view. The same can be said for the majority of mobile Twitter apps.
Use images! You're guaranteed to see positive results.
