LinkedIn Posts With Images vs Without: What the Engagement Data Actually Shows
Three independent datasets agree: image posts usually out-engage text-only posts on LinkedIn. But the size of the gap depends on how you measure it, and text still wins in some situations. Here's what the numbers say.
Key takeaways
- Across three independent 2025-2026 datasets, LinkedIn posts with an image consistently earned more engagement than text-only posts — no dataset we reviewed found the opposite.
- Socialinsider's analysis of 1.3 million company-page posts measured a 5.30% engagement rate for single-image posts versus 4.50% for text-only posts, with multi-image posts at 6.45%.
- The strongest evidence compares people against themselves: in a Contentin dataset of personal profiles, adding an image beat the same person's own text-only posts for 81.6% of 741 accounts, by a median of about 7 engagements per post.
- The gap is real but modest per post, and the studies are observational: they show image posts perform better on average, not that any image will lift any post.
- LinkedIn has not published official figures on image versus text performance, so treat these as third-party benchmarks and confirm them against your own post analytics.
"Always add an image" is one of the most repeated pieces of LinkedIn advice. Unlike a lot of LinkedIn folklore, this one has data behind it. We compared three independent datasets published in 2025–2026, covering more than 1.4 million posts, to answer a simple question: do LinkedIn posts with images really get more engagement than posts without them — and by how much?
The short answer
Yes. Every dataset we reviewed found that image posts out-engage text-only posts on average. The gap ranges from modest (about 0.8 percentage points of engagement rate) to large (roughly double the likes and comments), depending on whether you look at company pages or personal profiles, and at averages or medians. LinkedIn itself has not published official numbers on this, so everything below is third-party research.
What do the studies show?
1. Socialinsider: 1.3 million company-page posts
Socialinsider's LinkedIn benchmark analysed 1.3 million posts from 16,645 business pages published between January 2024 and December 2025. It measures engagement rate by impressions (engagements divided by impressions). The results by format:
| Post format | Engagement rate |
|---|---|
| Native document (carousel) | 7.00% |
| Multi-image | 6.45% |
| Video | 6.00% |
| Single image | 5.30% |
| Text only | 4.50% |
| Poll | 4.20% |
| Link | 3.25% |
A single image lifts engagement rate by about 18% relative to text-only (5.30% vs 4.50%). Multiple images push that to about 43%.
2. Contentin: personal profiles compared against themselves
Company pages are not personal profiles, and big-brand averages can hide a lot. Contentin's engagement benchmarks draw on 100,572 posts from 1,055 professionals' personal profiles (2023 to August 2026). The most useful part is a within-account comparison: 741 people who had published at least three image posts and three text-only posts were each compared only against themselves.
Result: image posts beat the same person's own text-only posts for 81.6% of those 741 accounts. The median gain was about 7 engagements per post (95% confidence interval: 6 to 8) and +0.77 percentage points of engagement rate.
This is the strongest evidence of the three, because account size, industry and audience cancel out. It does not rule out everything — people may save their best ideas for image posts — but it is much closer to a fair comparison than platform-wide averages.
3. LinkHub: 57,809 posts, likes and comments
LinkHub's format analysis (published July 2026) looked at 57,809 posts from its own platform data. Image posts averaged 127 likes and 35 comments; text-only posts averaged 65 likes and 16 comments. Images also earned more comments than carousels (29) or video (28).
These are averages, and averages are pulled up by a few viral posts, which is probably why this gap looks larger than in the other two studies. Read it as "images help", not as "images double your engagement".
Why do image posts get more engagement?
None of the studies tests the cause directly, but the plausible mechanisms are straightforward:
- They stop the scroll. An image takes up more of the feed and catches the eye before anyone reads the first line.
- They add dwell time. People look at a chart or screenshot, then read the text to understand it.
- They give people something to react to. A photo of an event or a slide with a bold claim is an easy prompt for a comment.
When is a text-only post the better choice?
An average advantage is not a rule for every post. Text-only still makes sense when:
- The writing is the value— a personal story, a strong opinion, or a short sharp insight. Adding a stock photo here is decoration, not information.
- You don't have a relevant image. A generic image is unlikely to help, and none of the studies separated useful images from filler.
- You post often. Mixing formats keeps your feed varied, and a good text post still beats a weak image post.
How to use images on LinkedIn posts
- Make the image carry information. A chart, a before/after, a screenshot of a result, a slide with your main point, or a real photo from the moment you describe.
- Keep the hook in the text.The first two lines still decide whether people click "see more". The image gets attention; the text keeps it.
- Try several images or a document postfor step-by-step or list content — both scored higher than a single image in Socialinsider's data.
- Check readability on a phone. Most LinkedIn reading happens on mobile; small text in an image is lost.
- Add alt text. LinkedIn lets you describe images for screen-reader users. It is good practice and takes ten seconds.
Test it on your own account
Benchmarks describe averages across thousands of accounts. Your audience is one specific group. A simple test: over your next 10 posts, alternate image and text-only, keep topics and posting times similar, and compare engagement rate (engagements divided by impressions) in LinkedIn's post analytics. Ten posts won't give you statistical certainty, but it will show whether the pattern holds for your audience.
AI-driven LinkedIn post engagement boosting: what works
Choosing the right format is one lever. AI can help with the others — as long as it improves the post itself rather than faking the response to it.
- Drafting stronger hooks. Generating several opening lines and choosing the best is faster with AI. The LinkedIn Post Generator writes hook-led drafts you then edit in your own voice.
- Scoring a draft before you publish. The Engagement Predictor rates hook strength, readability and structure, then suggests specific fixes — useful for deciding whether a post needs an image or a rewrite.
- Choosing hashtags. The Hashtags Generator suggests a mix of broad and niche tags for your topic.
What does notwork: bots, automated likes and comments, and engagement pods run by software. LinkedIn's User Agreement prohibits automated activity on the platform, and accounts that use it risk restriction. AI is worth using to make a better post — not to manufacture reactions to it.
About this analysis
We did not collect this data ourselves. The figures come from the three publishers linked above, each using its own sample and definition of engagement, so the numbers are not directly comparable with each other. We checked each figure against the original publication on October 4, 2026. Where the sources are silent — for example on which kind of image works best — we say so rather than guess.
Frequently asked questions
Do LinkedIn posts with images get more engagement?
On average, yes. Socialinsider's 2026 benchmark of 1.3 million company-page posts found single-image posts at a 5.30% engagement rate versus 4.50% for text-only. A within-account analysis of personal profiles by Contentin found images beat the same person's text posts for 81.6% of 741 accounts.
Which LinkedIn post format gets the most engagement?
In Socialinsider's 2026 benchmark, native document (carousel) posts led with a 7.00% engagement rate, followed by multi-image (6.45%), video (6.00%), single image (5.30%), text (4.50%), polls (4.20%) and link posts (3.25%). Those figures come from company pages; personal profiles may differ.
Do text-only LinkedIn posts still work?
Yes. Text-only posts still earn substantial engagement, and a strong text post beats a weak image post. Text works best for personal stories, opinions and short insights where the writing itself is the value and an image would be decoration.
Can AI boost LinkedIn post engagement?
AI can help with the parts of a post that drive engagement — drafting stronger hooks, tightening formatting, choosing hashtags, and scoring a draft before you publish. It cannot replace genuine interaction, and automated likes, comments or engagement pods violate LinkedIn's User Agreement.
What kind of image works best on a LinkedIn post?
None of the datasets we reviewed broke results down by image type. As a working rule, use images that carry information — a chart, a screenshot, a slide, a photo from the event you describe — rather than generic stock photos, and test the difference in your own analytics.
