A powerful LinkedIn strategy involves a two-part approach: use your main posts to share a contrarian or challenging point of view to capture attention and establish expertise. Then, in the comments section, remain unfailingly positive and supportive—even when disagreeing—to build relationships and goodwill.

According to a LinkedIn product head, the algorithm's main virality mechanism is "comment density." It favors posts that spark substantive, multi-reply conversations over those with many superficial comments like "nice post." Marketers should aim to create deep dialogues.

Don't partner with creators who solely post memes or chase engagement metrics. The best creators, regardless of follower count, are those who foster genuine, in-depth discussions in their comments. This conversational depth is a stronger indicator of influence and conversion potential than raw impressions.

To get a comment algorithmically boosted to the top of a popular post, aim to create "comment density." This means sparking a conversation that invites replies from other readers, not just the original poster. End your comment with a question like "What am I missing?" to encourage this broader engagement.

LinkedIn now shows impression metrics for comments, signaling their importance. Strategically leaving thoughtful, entertaining comments on others' posts can drive more page growth and followers than original feed posts. Treat comments like mini-posts to test content ideas.

Posting content without commenting ignores a significant source of algorithmic discovery. Leaving thoughtful, public comments allows lurkers in the feed to discover your domain expertise silently. For every post published, aim to write ten insightful comments on relevant industry discussions.

Simply posting content and leaving—or 'posting and ghosting'—is ineffective. LinkedIn's algorithm prioritizes posts that generate conversation. Engaging with comments, especially within the first couple of hours, is critical for signaling value and maximizing your content's reach.

For time-strapped professionals, a focus on leaving strategic, high-value comments can yield more reach than creating original posts. With LinkedIn increasing the visibility of comment threads and providing impression metrics for comments, this has become a legitimate and highly efficient strategy for engagement and personal branding.

The easiest way to increase your visibility is to consistently comment on other people's content. To make this effective, be strategic: comment on posts by industry leaders where your target audience will see your name, photo, and headline in a relevant context.
