Hashtags are used to categorize content on social media so that anyone interested in a topic can find posts with that hashtag regardless of whether they follow the poster. While hashtags originated on Twitter, they have now spread to other platforms like Facebook, Instagram, and Google. The appropriate number of hashtags to use varies by platform, with 1-3 generally being best across most platforms.

1. To or not to hashttag
…that is the
question

2. They’re used for categorization on
social media.
A hashtag will make your content
viewable by anyone with an interest in
your hashtag, regardless of whether
they’re part of your clan or not.

Hubspot
In the case of advertisements, Twitter
found that tweets without a # or @-
mention generate 23 percent more clicks.
The reason? Hashtags and @-mentions
give people more places to click inside a
tweet instead of focusing solely on a call-
to-action.

8. A rule of thumb could be: Don’t sweat your
amount of Instagram hashtags.

9. Facebook
Facebook posts without a
hashtag fare better than
those with a hashtag.

10. Find and manage your hashtags
With everything collected under one hashtag banner, you can
see at-­a-­glance the reach of your campaign and the discussions
happening around the topic.

The worst thing that can happen when
using a hashtag is to realize after it’s
tweeted that the same hashtag is used for
an entirely different topic.

11. Consclusion
Rule of thumb: 1 – 3 tags is best over all platforms.
