We all know that some videos and images get shared and go viral while others only catch a few eyeballs. Some sites like buzzfeed provide trending content which I find to be a good indicator. Where do you find viral content to share on social media?
This is a bit of a silly question. Content goes viral on social media sites. Sites like YouTube/Reddit would be a good starting point.
You can check big site similar to viralnova and buzzfeed. Rewrite their viral content, and post it. Find old posts, there are chances that it could get viral again.
