A Slack group, a broadcast channel, a Discord: the standard community playbook starts with building somewhere new. Meanwhile, your audience is already gathering in public every day, in the comment section under every post you publish.
They develop shorthand, react to each other and say exactly what they want. Meanwhile, brands spend months trying to create that behavior elsewhere.
Here are four ways to recognize and act on what's already forming in your comments, with a real brand example for each.
How do you build community in the comments?
You build community in the comments by treating the comment section as the place your audience already gathers, then acting on what shows up there: the language people use, the ideas they float and the questions they repeat.
That matters because community gives people a reason to keep coming back to your content. It makes them feel seen and turns passive viewers into participants. Danny Gardner, a social media intelligence leader who has run social listening across 25+ brands, sees the comment section as part of the content itself: "People don't just view content anymore - they rush to the comments. In many cases, the comments aren't just insight, they are the content."
4 ways to build community in the comments
1. Look at the language your audience already uses
When the same phrases keep appearing across your comments, your audience is developing its own shorthand. Reading for that shorthand tells you how people talk about your category, and you can use their words in your copy, briefs and product decisions.
Glossier did this while developing its Milky Jelly Cleanser. The team asked commenters what their dream face wash would do and collected the answers. "The story was huge. Almost 400 comments - all of which we recorded and consolidated and sent right to our chemist. There were key words like 'mild,' 'glowy,' 'moist.' That became the checklist for everything we wanted in the final product," said Lindsey Manas, Physical Product Coordinator at Glossier.
How to do it: Keep a running list of phrases that repeat across posts, then check which ones come up most often. Siftsy's keyword cloud sizes words and phrases by how often they appear, which makes recurring shorthand easy to spot.
2. Let comments shape your creative decisions
Some of the strongest campaign ideas start with a single comment.
