Find the best day and hour to post on TikTok for any creator. Get a 7x24 heatmap of views and engagement, top time slots, posting frequency and consistency.
Analyzes a TikTok creator's recent posts to determine the best day(s) and hour(s) to post by converting publish times to a chosen timezone, grouping posts by weekday and hour, and ranking day/hour slots using median views or average engagement rate; produces a 7×24 heatmap of hourly weekday slots with per-cell post counts, median and average views, and average engagement rate, calculates lift versus the creator's typical post, identifies top day+hour slots (with a minimum-sample requirement), ranks days and hours, computes posting cadence metrics (posts per week, average gap between posts, gap standard deviation, consistency score), and reports the analysis window and follower count along with a plain-language recommendation of the best posting slot.
