Did you know that tweets with hashtags generate twice as much engagement — which includes clicks, retweets, favorites and replies — as tweets without?
But don’t go crazy — use no more than one to two hashtags in your missives, as anything more than that actually has a negative impact on engagement.
On Instagram, the rules are a little different. Studies have shown that the more hashtags you use, the greater the impact — interactions are highest on Instagram when posts have eleven or more hashtags.
Facebook, meanwhile, is closer to Twitter — aim for just a couple of hashtags in your updates, as anything beyond this has a detrimental effect on results.
