The LinkedIn depth score is reshaping who gets seen

[1 min read time]

A post I published recently showed platform metrics I was genuinely pleased with: strong read-through, real dwell time, the kind of data that tells you someone stayed with your thinking rather than scrolled past it. The public engagement, the likes, the comments, was quiet. That gap between what the data showed and what the visible signals suggested told me something important. Not all that shines in likes is loved. And LinkedIn now knows the difference.

In early 2026, LinkedIn replaced its content ranking infrastructure with an AI system called 360Brew. The technical detail was published by a LinkedIn senior engineer in March, and it matters for anyone building a professional presence on the platform.

The old system rewarded reach: the wider your network, the further your content travelled. The new system rewards depth: how long someone reads your post, whether they make it to the end, and whether they return. A post read for thirty seconds now outperforms one with fifty quick likes.

The practical implications follow quickly from that shift. Document posts are currently the highest-performing format on the platform, with engagement rates running well ahead of standard text posts and image content. Posts containing external links receive markedly less distribution. Phrases designed to solicit comments, the "comment YES if you agree" approach that became ubiquitous a few years ago, now trigger algorithmic penalties.

LinkedIn is rewarding substance and penalising performance.

This matters for anyone building a professional brand or communicating on behalf of an organisation. The question shifts from "how do I get more engagement?" to "am I actually writing something worth reading?" That is a better question. It also means the discipline of long-form writing, content that takes a reader somewhere rather than interrupting their scroll, is back in favour. Not because long-form is fashionable, but because the platform can now measure whether people actually read it.

Write for the person in front of you. The algorithm will follow.

I have written about why video and carousels have lost their edge, and about the difference between knowing a platform and truly mastering it. This depth-score shift is the next chapter of that same story. The platforms that once rewarded the loudest voices are increasingly rewarding the clearest ones.

As always - thanks for the engagement … or should I say - thanks for the (estimated) one minute of dwell time!
