Tik Tok has rapidly become a popular choice for many people and businesses have been quick to create a presence on the short-form video app. If you currently use it or are thinking of doing so, keep in mind the importance of the caption.
Whilst hashtags are important, Tik Tok’s algorithm looks through your caption for keywords. Whilst many choose to put a caption of few words followed by an emoji and a bunch of hashtags, look to use up the 300 available.
Much like with Tik Tok’s short videos, you can use the space to tell the story. With a longer caption containing relevant keywords, your video can connect further, reaching a bigger audience.
