The TikTok engagement filter lets you search by specific engagement rate.
Heepsy calculates engagement rate using only engagements (interactions with content), and not views. Set the filter's slider and you'll only see TikTok creators whose engagement rate falls within the range you entered.
On the influencer's profile, you'll see their engagement rate in the Views & Engagement tab.
Be cautious of very low engagement rates, as they show a lack of interest or the presence of fake followers. Likewise, a suspiciously high engagement rate could show you that the influencer bought engagements.
