You may be surprised to learn that there are very specific and different rules for using hashtags on each social platform. This red, yellow, and green guide will explain how lenient and indulgent one should be when including hashtags in a post.

  • Red = Steer clear of using hashtags
  • Yellow = Use hashtags sparingly
  • Green = Go hashtag crazy.

Red. Stop. Move away from “shift” and “3” keys. Hashtags should not be a priority on Facebook. When applicable, tag a partner page instead of using a hashtag. Hashtags should only be implemented when it complements a call to action as part of a larger, cross-platform campaign.

Twitter logo Twitter
Yellow. Twitter is the birthplace of hashtags and still their most natural home. Tweets with hashtags get two times more engagement than tweets without, and 55% more retweets. However, using MORE than two hashtags in a tweet actually decreases engagement by 17%, so use them wisely.

Green. Feel free to go hashtag crazy. Hashtags (in the tagging section) on videos are important for search and discoverability. Use at least 3 tags on videos to increase the likelihood that users will find your content.

GPlus logo Google+
Yellow. Like YouTube, Google+ is a platform that is important for search. Google will automatically tag certain posts with relevant and popular hashtags. Hashtags can also be added to comments on a post. It is often good practice to tag or add search terms used for paid SEO and webpage strategies on Google+ posts as well. Use one or two hashtags that will help users discover content.

Instagram logo Instagram
Green. Instagram is home to #ThrowbackThursday, #TransformationTuesday, and other alliterations that allow users to post baby pictures. #There #seems #to #be #a #hashtag #epidemic #on #Instagram, but believe it or not, these people have the right idea. Hashtags are the primary way to find and browse new content on Instagram, and data has shown that interactions are highest on posts with 11+ hashtags. While over-hashtagging is distracting and considered poor etiquette, do not hesitate to include as many hashtags as are relevant to the post to increase discoverability.

Green. Like YouTube, hashtags are hidden on the back-end on Tumblr. This allows users to post more hashtags that cover all the aspects of the content. Use 9-12 terms that are both specific and general to completely represent the post content and the interests of the audience. Just remember that only the hashtags that are entered into the tag section will be clickable and searchable.

Pinterest logo Pinterest
Red. Believe it or not, hashtags may harm the reach of content on Pinterest. Clicking a hashtag will actually take you away from the content on the page, and to a list of all posts using that hashtag. This means that you will end up driving users to a list of other similar brands and competing content. Keywords, without a hashtag attached, are a better way to label content and help users discover it.

Vine logo Vine
Yellow. Like Instagram, hashtags are really the main way to find content, and like Twitter, Vine features trending hashtags and topics. It is best to include any and all relevant hashtags, but over-hashtagging isn’t proper etiquette. #DoItForTheVine

LinkedIn logo LinkedIn
Red. LinkedIn is unique in that the platform does not support hashtags at all. They are not clickable or searchable. A hashtagged word will just show up as normal text, and what good is a pound sign if doesn’t automatically hyperlink? Steer clear.
