Many TikTok influencers post a couple of times each day. However, being video-based, it is harder to make an excellent TikTok post than a text post on something like Facebook, or even an image-based post on a platform like Instagram. Quality is far more critical than quantity on TikTok. The videos may be short, but they must be worth watching and able to interest their target audience. If you want to build an enthusiastic following, you should post at once most days, however.
