TikTok videos can be embedded on a website using the TikTok Embedded Player feature. One method is to manually input links from TikTok videos and create TikTok feed widgets. Another method to embed tiktok is to use a social media aggregator like Idukki, which simplifies the process of integrating TikTok feeds into any website. The steps involve signing into the Idukki account, selecting the desired collection, adding TikTok feeds, previewing the collection, copying the HTML code, logging into the website's backend, pasting the embed code, and publishing the changes.
