TikTok claims that it makes content searchable and uses the description text to determine which videos it recommends to users.
A social media analyst, Matt Navarra, shares a screenshot of his message about the change.
Woah…! TikTok has increased the limit of video description characters to 2,200 characters
This is huge for creators and massive in terms of TikTok’s plans for becoming a search engine
