That analysis showed the shelf life of a Facebook post is short, but how short? How long does it take before a post or photo has received all the engagement it ever will? To find our answer Ryan Solutions tracked 30 resort and hotel Facebook, Instagram, and Twitter accounts that each had at least 200,000 Facebook fans, 75,000 Instagram followers, or 40,000 Twitter followers. For this sample 75% of all engagement was received within 4 hours on Instagram, 7 hours on Twitter, and 12 hours on Facebook. At least 90% of all engagement was received within 10 hours on Instagram, 21 hours on Twitter, and 24 hours on Facebook. Get the full story at Ryan Solutions
