Comment section strategy for founders: 5 comment traps that spread your idea

Most founders judge a video by its views. The comment section often does more work. It is where viewers check what the crowd thinks, and on TikTok it now feeds the search bar: search suggestions are generated in part from the comments under a video (Annabell et al., 2025).

Crowds also herd. In a randomized experiment on 101,281 comments, one artificial up-vote made a comment 32% more likely to get a positive rating from the next reader (MIT News). The first comments set the frame for everybody after.

So the comment section belongs in your packaging layer, next to the hook. Here is how we build it with founders.

Five comment traps

1. The deliberate mistake. A small error in a text box, a typo or a slightly wrong word, that people feel obliged to correct. Correcting inaccuracies is one of the top reasons people comment (Nieman Lab). Keep it away from anything that carries your authority: never a number, a price or a claim.
2. The knowledge gap. Show the result and hold back one piece of the how. The comments fill with questions, and your reply becomes the next video.
3. The nemesis bait. Define the person who will never buy from you because they reject your approach. Put their belief in the video, stated with conviction. They comment, your community answers them, and the idea gets argued in public by people who agree with you.
4. The role reversal. Play the nemesis yourself, then reveal the twist at the end. Viewers who leave early comment in agreement with the wrong side, and the people who watched to the end laugh at them. We used this with a 25-seat halal pizzeria whose owner pretended to rage against halal charcuterie, then showed the halal sign on his own restaurant. That account grew from 2,000 to 1 million followers in two years, and 1.6 million today.
5. The running gag. Give your community a private joke it can reuse under other people’s videos. Every time it appears, your idea and your name travel to places you never posted.

Trap or bait

Facebook has demoted engagement bait since 2017, including bait in comments and in video audio (Meta). The test is simple. If the comments under your video discuss your idea, you built a trap. If they say “yes” or tag a friend, you built bait, and the demotion is deserved.

Commenting as a founder

Founders should comment on other people’s videos, under their own name, with a line that makes the crowd laugh first and remember the idea second. Brands do it for fun: under one viral broccoli video, a hotel brand’s comment collected 1.1 million likes (OMR). A founder can do better, because the comment can carry a real idea.

Two rules. Say who you are: the FTC’s 2024 rule bans undisclosed reviews and testimonials by company insiders (Davis Wright Tremaine). And never fake a crowd: Meta found that the China-linked Spamouflage network, one of the largest fake-comment operations ever exposed, got no substantial engagement from real communities (The Register).

The demo trick

Next time you record a product demo, skip “comment DEMO to get the link”. Show the result and keep the name of the tool to yourself. If the feature is really good, viewers get frustrated and ask in the comments what tool you used, with far more motivation than a begged comment. Every one of those questions tells the algorithm, and every reader of the comments, that your product is worth looking for.

Comment traps are one more die in the dice system: a format you throw every week, read in the data, and keep or kill.
