TikTok is the best place to find short-form mobile videos that are exciting, spontaneous, and real. As one of the most popular apps in the world, TikTok gives businesses the chance to reach a large group of people who value entertainment and authenticity.
According to the official TikTok business blog, the ads should be longer. They say 24 seconds.
Videos with a duration of 21 to 34 seconds convert 2.8 times better than those under 21 seconds. Videos with a runtime of 10 to 20 seconds are good at generating impressions. But, for conversions, according to TikTok, the recommended time range is 21 to 32 seconds.
