Which Post Format Works Best for You?

The format that works best on LinkedIn depends on your audience, not on a generic benchmark. Across 25,150 posts from 66 Flux user profiles, carousels earn a median of 55 engagements while text posts earn 19 — but your own data may tell a completely different story. Flux's Content Type Breakdown chart ranks your formats by average engagement with a multiplier showing how each one compares to your overall average, so you can stop guessing and start doubling down on what actually works for you.

What do the benchmarks say about LinkedIn post formats?

Across 25,150 posts from 66 Flux user profiles, here is the median engagement by format:

Format	Median engagement
Carousel	55
Image	42
Video	33
Text	19
Article	12
Poll	10

Carousels lead by a wide margin — nearly 3x the engagement of a plain text post. But these are medians across dozens of profiles with different audiences, industries, and posting styles. A finance executive whose audience values concise text insights may get more engagement from text than from carousels. The benchmark tells you what tends to work across LinkedIn; your own Content Type Breakdown chart tells you what works for you.

How do I read the Content Type Breakdown chart?

Open your Flux dashboard and look at the Content Type Breakdown chart. Each bar represents a format — Carousel, Image, Video, Text, Article, Poll — and shows two things: how many posts you have published in that format and a multiplier comparing that format's average engagement to your overall average.

A multiplier of "1.8x avg" next to Carousel means your carousels earn 1.8 times more engagement than your typical post across all formats. A multiplier below 1.0x means that format underperforms your baseline.

Click any bar to filter the Top Posts table to just that format, so you can read the actual posts behind the number. The Best Format KPI card on the dashboard also drills into this view — tap it to jump straight to your top-performing format and see the posts that earned it.

Which format should I post more of?

The most useful insight in the Content Type Breakdown is not which format performs best — it is which format performs well but you barely use. That is your growth lever.

Look for a format with a high multiplier and a low post count. If your carousels show a 2.1x multiplier but you have only published four of them while you have 80 text posts at 0.7x, the data is telling you to shift effort toward carousels. You have evidence that your audience rewards them, and you have room to publish more.

Conversely, if you have been grinding out carousels because a blog post told you to but your multiplier for carousels is 0.9x while your image posts sit at 1.6x, the data says your audience prefers images. Trust the chart over the conventional wisdom.

The goal is not to abandon every other format. It is to tilt your mix toward the formats your audience actually rewards, using your own engagement data instead of someone else's benchmark.

What does the slide-count correlation tell me about carousels?

When you have enough carousel posts, Flux adds a slide-count vs. engagement correlation to the chart. This shows whether your longer carousels earn more engagement than your shorter ones, or whether there is a sweet spot.

Not everyone's audience behaves the same way. Some audiences prefer a tight five-slide carousel that makes one point well. Others reward a deep 15-slide walkthrough. The correlation line tells you which pattern holds for your posts, so you can stop guessing at the right carousel length and let the data decide.

How do I pull format data programmatically?

Edge

On Edge, you can ask Claude or your AI assistant to show you a format breakdown using Flux's MCP tools. Ask something like "show me which post formats perform best for my profile" and the AI will return your format breakdown with engagement averages, multipliers, and post counts — the same data as the dashboard chart, but in a format you can work with in a conversation, export, or feed into a content planning workflow.

This is useful when you manage multiple profiles and want to compare format performance across them without switching dashboards, or when you want to combine format insights with topic or timing data in a single AI conversation.

Frequently asked questions

Does Flux track impressions by format? No. LinkedIn does not expose impressions to third-party tools. Flux measures engagement — likes, comments, and shares — so the format comparison is based on what your audience actually reacted to, not passive views.

Is the Content Type Breakdown available on all plans? The Content Type Breakdown chart is available on Pulse and above. Pulling format data programmatically through AI tools requires Edge.

What counts as a "carousel" in Flux? LinkedIn calls them document posts. Flux labels them as Carousel in plain language. Any PDF or multi-slide document uploaded as a post is categorized as a carousel.

How many posts do I need before the format data is useful? You need enough posts in each format to see a meaningful pattern. If you have only one or two carousels, the multiplier for that format is unreliable. Focus on formats where you have at least five to ten posts.

Should I stop posting in low-performing formats entirely? Not necessarily. A format with a low multiplier might still serve a purpose — text posts are fast to create and can sustain your posting frequency even if they earn less engagement per post. Use the data to shift your mix, not to eliminate options.
