# Instapect

> Instapect audits any public Instagram profile and returns a chart-rich report: engagement rate by followers measured against peer percentiles, median engagement, comment-to-like ratio, posting cadence, a content leaderboard and a transparent 0-100 Instapect Score. Every report is built only from lawfully visible public signals — no reach, impressions, demographics or Story insights.

Reports are free to read without an account. Each report states its sample size and retrieval date: `Public-profile audit · N posts sampled · retrieved <date>`.

## Methodology

- Engagement rate by followers = (avg likes + avg comments) / followers x 100.
- Median is always reported alongside the average so viral posts cannot distort the read.
- Sub-scores are shown with the formula that produced them; unmeasurable inputs are excluded, never zero-filled.
- Grading is tier-relative: an account is scored against percentile anchors for its own follower tier.
