Plot audience members on a two-by-two matrix. The horizontal axis measures regularity of engagement, from little or none to repeated interaction. The vertical axis measures adoption of the brand or community’s relevant beliefs, using belief as a proxy for affinity, selection, and advocacy. People who both engage regularly and substantially share the beliefs occupy the upper-right quadrant and constitute the core community. Subscribers who never interact or active critics may be audience members without meeting that definition. Because belief is difficult to observe directly, teams use proxies such as sharing, advocacy, product behavior, and periodic surveys. The remaining quadrants become movement opportunities rather than automatically counting as community.
Origin
Extracted from Marketing Against The Grain as the hosts tried to distinguish community from subscriptions and chat-channel membership.
Core principles
- 01Subscription alone does not prove community membership.
- 02Engagement indicates an active relationship.
- 03Belief adoption indicates affinity and likelihood to choose or advocate.
- 04The highest-engagement, highest-belief quadrant is the core community.
- 05Behavioral proxies and surveys can estimate belief when it is not directly observable.
How to run it
- 1
Define the purpose
Specify what the community is intended to create, such as affinity, advocacy, learning, contribution, or product success.
Pro tip Use the purpose to choose meaningful engagement signals.
Watch out Without a purpose, any audience activity can be mislabeled as community.
- 2
Measure engagement
Choose behaviors demonstrating an active relationship, including opening, replying, sharing, attending, contributing, or interacting with peers.
Pro tip Weight repeated meaningful behavior above passive account creation.
Watch out Membership in a channel does not guarantee engagement.
- 3
Define belief adoption
State the few beliefs or approaches members would need to share to prefer and credibly advocate for the community.
Pro tip Phrase beliefs as testable positions rather than generic values.
Watch out Do not equate brand awareness with belief adoption.
- 4
Estimate the quadrants
Combine behavior, advocacy proxies, and sampled surveys to place or estimate audience groups on both axes.
Pro tip Report estimates honestly when individual belief data is unavailable.
Watch out Survey responses and actual behavior may diverge.
- 5
Move adjacent groups
Design paths that deepen belief among engaged people and increase engagement among aligned but passive people.
Pro tip Use different interventions for each quadrant.
Watch out Do not treat every subscriber as if they already belong to the core.
In the wild
A company measures repeat opens, replies, sharing, and event attendance. It surveys a sample of active readers about three distinctive beliefs and learns that roughly 40% of repeat openers share them. Rather than calling the entire subscriber list a community, it estimates the core from high-engagement readers who also demonstrate belief alignment.
→ The company gains a more defensible community size and clearer paths for deepening affinity.
Common mistakes
Counting every subscriber
A subscription records access or interest but does not prove engagement or shared belief.
Counting only chat accounts
Restricting community to Slack or Discord misses highly engaged, aligned people on other media.
Pretending belief is directly measurable
Belief usually requires proxies, sampling, and transparent estimation rather than false precision.
Is it for you?
Best for
It is best for marketers measuring communities spread across newsletters, social channels, products, Slack, or Discord.
Not ideal for
It is not ideal when the organization cannot define shared beliefs or observe any meaningful engagement behavior.
From the transcript
“what you're kind of saying is regularity of engagement, right? Do they on one end they don't engage with you at all?”
“The vertical axis there, I would say, is how much they adopt your beliefs.”
“that upper right hand quadrant of that two by two is community.”
