What should you post on LinkedIn right now, carousels, video, or plain text? Agency owners ask me this every week, usually after watching another expert declare that video is the future. The data finally gives a real answer, and it is not the one most people want to hear. Carousels win reach. Text wins clients. If you optimize your entire content mix for impressions, you will build an audience that watches you and never pays you.
The numbers come from Metricool's LinkedIn Trends study, which analyzed 673,000+ posts. According to Metricool's report, carousels average 1,451 impressions per post vs. 605 for video, posts with a direct question generate 77.39% more comments, and 50% of total impressions happen within the first 48 hours of posting. That is a 2.4x reach advantage for carousels over video. The study also found that personal profiles outperform company pages on engagement by 63%, which settles an argument a lot of agencies are still having internally.
Here is who this matters for. If you are an agency owner between $200k and $2M in revenue, a ghostwriter charging $5k to $30k per month, or a founder running personal-brand content to feed your own pipeline, your format decisions are business decisions. You are not posting for reach as an end in itself. You are posting so that a specific kind of buyer trusts you enough to start a conversation.
This is not for creators whose audience is the product. If your revenue model is sponsorships and you need raw impressions to sell, run the carousel playbook at full volume and skip the rest of this article. If you are still trying to reach your first 500 followers, this will not change your model either. Format strategy matters once distribution exists, not before.
For everyone else, the mistake is treating reach data as buying data. This is what I call the Reach-Revenue Split. Every format on LinkedIn does one of two jobs. Reach formats put you in front of strangers. Revenue formats convince a warm reader that you understand their business better than they do. Carousels, question posts, and broad how-to content are reach formats. The post that convinces a founder to send a DM is almost never a carousel. It is usually a short text post with a sharp opinion, the kind of post the reach data rates as mediocre. Confuse the two jobs and you end up with impressive analytics attached to an empty pipeline.
What the LinkedIn algorithm data actually tells you
Read the Metricool numbers as a map of attention, not a map of money. The 48-hour finding is the most useful one in the study. If half of your total impressions arrive in the first two days, then spacing matters more than volume. Three strong posts a week that each get a full 48-hour window will beat seven rushed posts that cannibalize each other's reach. The question-post finding, 77.39% more comments, tells you how the algorithm rewards conversation. But comments from peers are not the same as messages from buyers. The people who hire a $5k-per-month ghostwriter or a positioning consultant rarely comment at all. They read silently for weeks, then show up in your inbox ready to talk. This is exactly why the dashboard undercounts what matters, something I unpack fully in how to measure LinkedIn success beyond your analytics dashboard.
The personal-versus-company finding deserves a decision, not a nod. A 63% engagement gap means the founder's profile is the distribution asset and the company page is an archive. If your agency is still splitting effort between the two, you are funding the weaker channel out of habit.
How to build a LinkedIn content mix that converts
Run the Reach-Revenue Split as a weekly ratio. Two reach posts built on the formats the data favors, carousels and direct questions, aimed at people who do not know you yet. One revenue post, a text post under 250 words that takes a position only someone with real client experience could take. The reach posts fill the top of the funnel. The revenue post converts the readers who have been watching quietly. Most creators run five reach posts and zero revenue posts, then wonder why 5,000 followers produce no pipeline. A smaller number run all conviction and no reach, and their sharpest thinking dies at 300 impressions. The ratio is the strategy.
Timing folds into the same system. Because half your impressions land inside 48 hours, give your revenue post the best window you have, the day and time your buyers actually scroll, and let the reach posts take the leftover slots. Reach content is replaceable. The post that demonstrates judgment is not.
The strategic implication runs deeper than formats. LinkedIn performance data is now public and abundant, and everyone will read it the same lazy way, as a leaderboard of formats to copy. Expect a flood of carousels over the next year, and expect their reach advantage to shrink as the feed saturates. What will not saturate is demonstrated judgment, because it cannot be templated. The operators who treat the data as a division of labor, reach formats for strangers and conviction posts for buyers, will compound both audience and pipeline while their competitors optimize themselves into an audience that never buys. Your format mix is not a content decision. It is a decision about which of those two businesses you are building.
