TL;DR: Three things shifted on LinkedIn in May that change how a post actually reaches people. Depth Score (the time a reader spends with your post) became the dominant ranking signal, PDF document carousels lead the platform in engagement at 6.6%-7%, and an external link in the body of a post cuts median reach by 18.8%. Here is what to do about it this week.

LinkedIn is not the platform it was a year ago. The current architecture, 360Brew, is a single LLM with 150 billion parameters that replaced every previous ranking system. It rewards one thing above all: depth. How long people stay with your post, not whether they tapped like and bounced.

Three updates landed in May that change the picture in practice, and all three are backed by data published in the last week. Worth knowing.

1. Depth Score: dwell time is now the most important signal

Richard van der Blom analyzed 1.3 million posts over the past month and surfaced one number worth internalizing. Posts where the reader stays between 0 and 3 seconds get 1.2% engagement. Posts that hold readers for 61 seconds or more get 15.6%.

A 13x difference.

The implication: writing for virality, the "three short lines and a punch with a logo at the bottom" approach, is no longer the main growth path. The new path is writing that holds the reader. A hook that pulls them in, a structure that keeps them reading, an ending that doesn't dodge. New data this week from Influence Flow points the same way: shorter, story-driven posts built for saves, not for virality, are winning.

What to do this week: take a recent post that performed well. Check not just likes but average time spent. If you have LinkedIn Premium Analytics, dwell time is in there. If not, the closest proxy is the save-to-like ratio. High saves signal depth.

2. PDF carousels lead the platform on engagement

The format winning right now by a wide margin is the PDF document carousel. This week's numbers: 6.6%-7% engagement, the highest format on LinkedIn, up 14% year over year. Native video sits second at 4.7%, and still beats YouTube links by more than 300%.

Why does it work? Exactly because of the previous point. A carousel forces the reader to swipe, continue, linger. Each slide holds them for a few more seconds. Depth Score rises on its own.

What to do this week: pick one post you want to blow up, and instead of publishing it as text, turn it into a 7-8 slide carousel. One hook slide, five content slides, one CTA slide. If you don't have a designer, Canva has templates that work fine. The only real creative call is making the hook visual and clear.

3. An external link in the body cuts reach by 18.8%

This rule is not new, but it got fresh validation this week. The same van der Blom study (1.3 million posts, March-May 2026) showed that a post with an external link in the body text gets a median 18.8% less reach than the same post without the link.

The classic workaround still works: link in the first comment. No tricks, just write a value post, and in the first reply to yourself, add "Link for anyone who wants to go deeper:" with the URL.

What to do this week: look at your last three posts. If the link is in the body, edit and move it to the comment. Watch reach over the next month and you will see the difference.

Bonus: three more things worth knowing

Advice Sessions launched officially on May 12 for Premium Business users in the US. Consultants and freelancers can set an hourly rate, take bookings, and process payment directly from their profile, without Calendly or Stripe. LinkedIn's fee has not been announced yet, which means conversion potential is high for early movers.

Off-Platform Event Ads reached full global availability. Until this week, anyone running a webinar on Zoom or Webinar Pro had to build a parallel LinkedIn Event Page to use Event Ads. Now you can send the click directly to your external registration page. Saves hours of setup and keeps the tracking in your own system.

AI Content Crackdown: Generic Posts Get Suppressed. LinkedIn announced it will suppress (not delete) generic AI-generated posts from feed recommendations. A flagged post stays visible to direct connections but won't spread further. The detection system targets engagement bait, recycled thought leadership, and formulaic patterns. LinkedIn reports 94% accuracy in early tests (no data on false positives yet). Bot-generated comments are also in scope. The distinction they're drawing: AI-assisted content with original ideas is still fine; fully AI-generated slop with no human layer gets buried. One specific format they named as a trigger: the "it's not X, it's Y" structure.
Note the irony ,LinkedIn is owned by Microsoft, which heavily funds OpenAI, and LinkedIn itself offers an AI post-writing tool. They built the firehose and the filter at the same time.

The bottom line for this week

LinkedIn in June 2026 rewards depth, punishes reach-chasing, and now actively buries content that a human didn't actually think through. The three algorithm updates and the AI crackdown point in one direction: the platform is pricing in originality. Generic is not just less effective, it is starting to get suppressed at the infrastructure level.

Which of these was already on your radar, and which is new?
