1. Exposure
The person has an opportunity to encounter the content.
Engagement exchange is the multi-signal layer of a social exchange system. It covers different public actions, but a like, view, follow, comment, save, and profile visit describe different moments in the audience journey.

| Signal | What it can describe | What it does not prove |
|---|---|---|
| Like | A lightweight visible response | Deep attention or future loyalty |
| View | Exposure to video content | Completion, satisfaction, or recall |
| Comment | A visible conversation action | Positive sentiment or relevance by itself |
| Follow or subscription | Interest at profile or channel level | Permanent retention or future reach |
| Share or save | Possible utility, relevance, or intent to revisit | Why the user acted or what happened later |
| Profile or link action | Interest beyond one item | A conversion without downstream evidence |
The person has an opportunity to encounter the content.
The person pauses, watches, reads, or otherwise consumes enough to respond.
A visible action such as a like, comment, save, or share occurs.
The person returns, follows, visits a destination, inquires, or converts.
For likes specifically, continue to how a like exchange works. For the complete credit and platform model, return to Social Media Exchange.
Did the requested public action appear during the observation period?
Did the visible total remain, and did people return?
Did response match the topic, audience, language, or creator goal?
Do not use it to disguise weak content, promise a client guaranteed organic growth, replace advertising attribution, or infer sentiment from a raw count. Never use a service that asks for passwords, session cookies, recovery codes, or automation access.
No. Its usefulness depends on the content goal, audience fit, timing, and what happens after the visible action.
No. Networks control distribution using many signals and conditions that an exchange service cannot control.
Only when there is a clear reason and baseline. Testing one main variable first usually produces easier-to-interpret evidence.
