Tweet post lifespan = 15 minutes (Avg.)
Facebook post lifespan = 6 hours
LinkedIn post lifespan = 24 hours
YouTube post lifespan = 20+ days
Make sure you optimize your posts for retweets and shares. You can also try to “boost” a Facebook post with an ad to extend lifespan. With Twitter, “pin” tweets to the top your profile page to guarantee a greater lifespan. For a LinkedIn post, add content to your profile and join groups to share that content there. Add relevant keywords in your YouTube video title, description, & tags.
Lastly, #Hashtags can help extend or “stretch” lifespan for all social media platforms posts.
