What are the best hashtags to use on TikTok? Me and my clients always use hashtag FYP, which stands for for you page. And then from there we change the two other slots depending on what the video is about. For example, if we're making a video about Facebook ads, we'll use hashtag Facebook ads and hashtag Facebook ads tutorial. The key takeaway is to use hashtags that have a lot of views. These hashtags have already found your ideal customer profile for you, so just use them.
