Chances are you've likely seen a word or phrase preceded by a # (pound/hash) symbol used on social media. When done correctly, using a #hashtag allows everyone to find this keyword or topic more easily.
Ideally, #hashtags should be simple, easy to understand, and used sparingly.
As we've shared before, #skylake18 (Sky + Lake + Current Year) is our preferred #hashtag. Using each word individually (#sky #lake #18) would result in having to sort through countless posts containing any one of those words. Using just #skylake would bring up posts for other nouns also named Sky Lake. Using #skylakecampandretreatcenterinwindsornewyork is just way too long and hard to read.
Depending on which social media platform you're using, you may get either more or less engagement depending on the number of #hashtags used. For instance, on Facebook and Twitter less usage equals greater engagement. Whereas on Instagram, more usage of #hashtags leads to greater engagement (although engagement tanks when more than ten are used.) There are some minor exceptions to these rules (such as using a funny #hashtag on occasion), but we recommend beginners stick to the basics.
