LinkedIn Just Admitted a Lot of Its Comments Are Bots. Here's Why That Matters.

LinkedIn quietly made a pretty significant change to how comments get ranked, and we think it deserves more attention than it's gotten. Replies now get surfaced based on relevance to the individual viewer instead of just posting in chronological order. Buried in the reasoning behind the update was a number that stopped us: LinkedIn found that 30% of comments posted between April and June were entirely AI-generated.

Read that again. Nearly a third of the comments on the platform, in a three-month window, weren't written by the person whose name was attached to them. That's not a rounding error, that's a real erosion of what a comment section is supposed to be, which is people actually reacting to what you said.

We've talked this week about how skeptical people have gotten of AI-generated content in general and what that means for trust in sales conversations specifically.

This is the same story showing up at the platform level. LinkedIn's engagement had actually risen 18% year over year, but a meaningful chunk of that growth was hollow, generated by engagement pods and automated reply tools rather than actual professional discourse. The platform is now actively penalizing that behavior in the ranking algorithm, which tells you it got bad enough that the business case for fixing it outweighed the engagement metrics it was propping up.

For anyone building a content or thought leadership strategy on LinkedIn, and that's most of the people we work with, this changes the math. Chasing comment volume through pods, automation, or "engagement groups" isn't just ethically thin, it's now actively working against you in the algorithm. What's rewarded instead is the harder, slower thing: posting something a real person actually wants to respond to, and then showing up to respond back.

We'd rather build a strategy around fifteen real comments from people who mean it than a hundred generated by a bot ring, and now the platform agrees with us. If your LinkedIn strategy has been leaning on volume over substance, this is the moment to rethink it before the algorithm makes the decision for you.
