Hashtag history and what’s current

We’ve been using hashtags for over a decade to organize information, break news, track campaigns across platforms and even land the punchline to some jokes.

Some practices have become tried and true; for example, using more than one or two hashtags on Twitter is still considered spammy and Facebook still sees comparatively little use of hashtags. Meanwhile on Instagram, hashtags continue to be the key to discovery- now you can even follow them!- and LinkedIn has reinstated the use of hashtags after several years of not supporting them.

It can be a lot to keep up with, so we rounded up resources for deeper reading on the areas most applicable to your brand, industry, and strategy below.
