The Engagement Rate filter (Creator Filter section) is a min/max range slider from 0 to 20%. Only creators whose average engagement rate lies inside the range are shown; leaving the slider at the full 0–20% range deactivates the filter. Setting only a minimum (e.g. ≥ 3%) or only a maximum works as well.
On Instagram you can choose whether the filter applies to posts or reels — influData indexes the engagement rate separately per content type. On YouTube the toggle switches between videos and shorts. The engagement rate describes the share of viewers who interact with the content through likes and comments; it is averaged over the creator's recent content, so very new or rarely posting accounts can show less stable values. The filter is not available for Twitch.
