What a burst is

A burst is a sudden jump in follows that stands out from normal growth patterns.

Bursts can be legitimate (a viral post, a press hit) or suspicious (purchased followers, low-quality traffic).

Signals that matter

The key question is whether engagement and audience quality move with the burst.

Look for mismatches: big follower spikes without corresponding engagement, or clusters of thin/suspicious accounts.

Explaining what happened

Heroic Signal™ flags suspicious bursts and pairs them with timelines, engagement totals, and follower quality signals so you can explain what happened.
