Though hashtags are not required by any means, if you choose to use them for regular posts about your chapter, please use the standard #SUCity. For example, #SUSingapore, #SULagos, #SUTokyo, etc.
For cities with longer names, you may choose to use a commonly known abbreviation. For example, #SUSF (San Francisco), #SURio (Rio de Janeiro), #SUNola (New Orleans)
Best Hashtag Practices
Try not to stuff your social media posts with hashtags. This typically does more harm than good in terms of engagement. A good rule of thumb is that a Facebook post should never have more than 1 or 2 hashtags, a tweet no more than 3. Instagram posts may contain many hashtags if they're all added to the end of the post after a few paragraph breaks (i.e., hitting Return).
