There’s a version of “community building” that looks like a project plan. You pick a platform, set it up, invite your audience, and wait for something to happen.

And, most of the time, not much does.

Brands keep looking for a new place to build community when the one they already have is sitting right there, updating in real time, every time they post.

The comment section is so much more than a feedback form, or an engagement metric. For the brands paying close attention, it’s where community actually forms - and where the signals are, if you know what to look for.

Here are five of them:

When the same phrases keep showing up across comments, it means your audience is developing their own shorthand.

Glossier used this exact approach when building their now-bestselling Milky Jelly Cleanser. They asked commenters what their dream face wash would do, collected hundreds of responses, and sent the recurring language - words like “mild”, “glowy”, “moist” - directly to their chemist.

The product spec came from the comments, and the community shaped the thing they were all eventually going to buy (and love).

Some of the strongest campaign ideas can come from a single comment.

Look at Topgolf. When they posted a video of a work Christmas party, a commenter named Logan Phillips replied that they’d better have a broken net fixed by January 9th because his office party was booked there. Topgolf’s response became a viral moment of its own.

All because they picked up on what was happening in the comments, and ran with it.

People are more invested in things they helped shape.

SULT, a hydration brand, let their community co-build the product from day one. When they posted packaging options for a vote, a LinkedIn stranger messaged to say he didn’t like any of them and sent a completely different design. That became the box they launched with. Plus, it came out better and cost less.

Before you finalize a campaign concept, product name, or creative direction, consider floating it where your audience already is.

Brevité, a camera bag brand, builds their content strategy around exactly this. Someone asks if a Stanley cup fits in the bag, they make a video showing it. Someone worries it won’t fit three camera bodies, they make a video showing that too.

When your audience sees their questions showing up in your content, they start treating the comment section like a direct line to your brand - which means they keep coming back, keep engaging, and keep asking.

None of this requires a new platform or a community manager or a 12-week rollout.

All you need to do is start treating the comment section like the resource it already is.

The gap between where campaign decisions get made and where audiences actually live keeps coming up.

Luckily for us, it’s one of our favorite topics.

In the latest Link in Bio interview, SheaMoisture Social Lead Alyssa Ackerman, makes the case that social teams are consistently the most culturally plugged-in people in the building - and consistently the last ones in the room.

“Would you rather have my input now or would you rather watch the asset tank later?”

The comment section is one of the clearest signals a social team has. The brands getting right are bringing that data into the room before the brief is written, not after the asset is live.
