Frequently Asked Questions
What public influencer data can I extract?
Follower count, following count, post/content count, public bio and contact links, engagement signals on public posts (likes, comments, shares), posting frequency, and content category classification.
How do I calculate engagement rate from extracted data?
Engagement rate = (average likes + comments per post) / follower count × 100. Extract recent posts to calculate the average, then normalize by follower tier for benchmarking.
