TikTok no longer allows direct calls to action in captions, video text, or comments, such as "link in bio," "website in our profile," or "go check it out at yourwebsite.com." Here are some tips for getting around this limitation:
Use special characters, like "L!nk in b!0," but this can seem scammy.
You should make Double letters, such as "Weebsite in BI00," but this doesn't look professional.
Use indirect calls to action. Show the website in your video or write a caption urging people to check it out. Encourage comments asking where to get the product and then pin a response with the information. Pin a comment with a special offer or discount code. Note that a video with "link in bio" in the caption will not reach the "For You" page, and comments with these words will be hidden from other users (although you will still be able to see them).
