That, according to social media analytics firm Locowise, is the optimum number of hashtags an Instagram post should have to earn the most engagement.
Locowise derived that figure by examining over 1,500 active Instagram accounts that posted 135,000+ posts in the 3-month period and had 300+ million followers combined. Of those, nearly 14 percent of all posts had no hashtags, while those with three had the highest level of engagement. However, those with no hashtags had just a slightly lower engagement rate than those with three.
Indeed, Locowise finds engagement rates decline as you tack on additional hashtags above three.
On Twitter, the firm found that tweets with no hashtags outperformed those with hashtags. This despite the fact that we have Twitter to thank for hash-tagging in the first place.
The moral of the story? A hashtag or three will help you attract eyeballs on Instagram, but not Twitter.
