TikTok Is Now a Search Engine — And Most Captions Aren't Written for It
Gen Z uses TikTok to search for product recommendations, tutorials, and local businesses more than they use Google. A TikTok SEO optimizer helps you write captions and hashtags that surface in those searches without sacrificing FYP reach.
TikTok SEO and FYP use different signals
TikTok's search algorithm prioritizes keyword relevance in the caption and spoken words. The FYP algorithm prioritizes completion rate and early engagement. A caption optimized for both serves both discovery paths simultaneously.
Tiered hashtag mix for reach and relevance
A single trending hashtag alone doesn't explain to TikTok what your content is about. A tiered mix — trending for reach, mid-size for context, niche for specificity — gives the algorithm multiple classification signals.
