Types of Communities: a guide for marketers

A guide to the types of communities and why understanding them matters for effective marketing.

The 5 types of communities and why it matters for marketing

Communities shape every aspect of human behavior, from the products we buy to the brands we trust. They’re the invisible networks that influence our decisions, validate our choices, and define who we are.

Think about your last major purchase. Chances are, you didn’t make that decision in isolation. You probably asked friends, read reviews, checked forums, or sought advice from people who share your interests or circumstances. That’s community influence in action, and it happens millions of times every day across every industry.

The most successful brands don’t just market to communities: they become valued members of them. They understand that authentic engagement creates organic growth as community members naturally share messages they find meaningful. This approach builds deeper, more sustainable relationships than traditional advertising ever could.

1. Communities of Interest

What defines a community of interest

Communities of interest bring together people united by shared passions, hobbies, or enthusiasms. Unlike professional networks or neighborhood groups, these communities form around what people love to do, talk about, and experience together. Members connect to explore, celebrate, and deepen their interest through knowledge-sharing and social interaction.

These communities thrive on collective excitement and identity formation around specific interests. Whether it’s vintage motorcycles, Korean skincare, plant-based cooking, or fantasy football, the shared passion creates a strong sense of belonging that often becomes part of how members see themselves.

Real-world examples

Gaming communities represent some of the most vibrant interest-based groups online. Discord hosts thousands of communities where members discuss strategies, share accomplishments, and build genuine friendships.

Fitness communities have transformed how people approach health and wellness. Peloton created spaces where members share achievements, support each other’s goals, and form identities around their fitness journeys.

Food and cooking communities show how traditional industries can reinvent themselves through community building. King Arthur Flour transformed from a commodity product into a beloved brand by building a community of home bakers who share recipes, troubleshoot problems, and celebrate baking successes together.

Marketing strategies that work

• Create content that celebrates the passion itself, not just your products. REI publishes guides, stories, and resources that enrich people’s connection to nature.
• Listen carefully to community conversations for unfiltered insights into what your audience truly cares about.
• Partner with authentic community voices rather than traditional celebrities.
• Invite community members into your development process through testing programs or idea workshops.

2. Communities of Practice

What defines a community of practice

Communities of practice unite people who share a common profession, craft, or discipline. Unlike casual interest groups, these communities focus on professional development, problem-solving, and advancing skills within a specific domain. Members come together to learn collectively, exchange techniques, and establish standards of excellence in their field.

Real-world examples

Developer communities gather on platforms like Stack Overflow and GitHub to share code, solve problems, and discuss best practices.

Healthcare professional networks on platforms like Doximity and Medscape have become essential hubs.

Design communities on platforms like Behance bring together graphic designers, illustrators, and digital artists who share work, offer feedback, and discuss industry trends.

Marketing strategies that work

• Provide technically accurate content that genuinely advances professional practice. HubSpot created comprehensive resources that helped marketing professionals improve their craft.
• Offer webinars, workshops, and certification programs that enhance professional skills.
• Celebrate community expertise by highlighting members’ achievements and knowledge.

3. Communities of Place

What defines a community of place

Communities of place form around shared geography: the social connections among people who live, work, or gather in particular locations. These might be neighborhoods, towns, cities, or regions where physical proximity creates shared experiences, concerns, and local identity.

Real-world examples

Neighborhood business alliances often form communities that coordinate efforts. The Portland Business Alliance brings together over 1,900 local businesses.

Regional identity movements create strong community identities that influence consumer choices. Portland’s Stumptown Coffee built its identity around association with regional character and values.

Marketing strategies that work

• Customize your messages to reflect local cultural references, dialect, landmarks, and concerns. McDonald’s balances global brand consistency with localized menu items.
• Support local events, infrastructure, or causes that matter to the community.
• Use precise geographic targeting through modern digital advertising platforms.

4. Communities of Action

What defines a community of action

Communities of action unite people working toward specific goals or changes in the world. Unlike communities based on shared interests or location, these groups form explicitly to make tangible impact.

Real-world examples

Environmental activism groups like Surfrider Foundation bring together people committed to ocean conservation.

Health advocacy organizations focused on specific causes unite around improving outcomes for affected populations.

Marketing strategies that work

• Clearly communicate your genuine commitment to values that matter to action-oriented communities.
• Collaborate with communities to create concrete, measurable change.
• Offer skills, infrastructure, or tools that help communities achieve their goals.

5. Communities of Circumstance

What defines a community of circumstance

Communities of circumstance form among people sharing common life situations, challenges, or transitions. These groups form because members find themselves in similar circumstances, such as new parenthood, health diagnoses, or career transitions.

Real-world examples

New parent groups, whether online forums or local meetups, form strong communities to navigate the challenges of child-rearing.

Health condition support groups bring together people diagnosed with specific conditions.

Marketing strategies that work

• Develop resources that address the unique challenges of transitional periods.
• Create platforms where people in similar circumstances can find each other.

The overlapping nature of communities

Communities rarely exist in isolation or fit neatly into single categories. They blend, evolve, and transform over time in ways that create rich, complex social ecosystems.

Measuring community engagement: beyond metrics

Focus instead on relationship quality indicators: How often do community members reference your brand in helpful contexts? Do they defend your brand when others criticize it?

Building a community-centered marketing strategy

Start by mapping the communities your customers actually participate in rather than the demographics you think they represent.

The future of community-based marketing

Emerging technologies will continue to reshape how communities form and function, but the fundamental human need for connection and belonging remains constant.
