Find Your Lane: Building Topical Authority

The single biggest change in how LinkedIn ranks content is that it now checks whether you actually know what you are talking about. Posts from people with recognizable expertise in a subject travel several times further than the same post from an account with no pattern. This article covers how that works and how to build it deliberately.

This is accessible to all roles and permission levels.

Understand what topical authority is

LinkedIn reads your profile, your headline, your experience and your posting history, and forms a view of what you are credible on. When you post inside that subject, your post is distributed more widely. When you post outside it, distribution drops.

This is not a reputation score you can see, and there is no badge for it. It is the accumulated effect of posting recognizably about the same territory over time.

Two things follow, and they are the whole strategy:

Narrow beats broad. An account that posts consistently about supply chain risk outperforms one that posts about supply chain risk, hiring, productivity tips and holiday photos.
Your profile has to back it up. If your headline says nothing about your subject, you are asking the platform to take your word for it.

Choose your lane

Your lane is not your job title. It is the two or three things you could talk about for ten minutes without preparing. A useful way to find it:

Write down the questions colleagues actually come to you with.
Write down what you have learned in the last year that you did not know before.
Write down the part of your work you would happily explain to someone outside the company.

Where those three overlap is your lane. It should be specific enough that someone could describe it in a sentence, and broad enough that you can post about it twice a week without repeating yourself.

A lane is not a cage. Roughly eight in ten of your posts sitting clearly inside your subject is enough. The occasional personal post or company milestone does not undo it.

Make your profile agree with your posts

Because the platform compares what you post against who you say you are, a mismatch costs you reach. Worth checking:

Your headline says what you do and for whom, not just your title.
Your About section names the subjects you work in, in the words other people would use.
Your experience entries describe the work, not just the role.
Your skills reflect the subject you post about.

This is worth doing once, properly, before you worry about posting cadence. It affects every post you make afterwards.

Build it over time, not in a week

Topical authority accumulates. The mechanics reward the boring version of consistency: a steady two to three posts a week inside your subject, over months. See How Often to Post, and When.

The fastest way to build it is not posting more, it is commenting well on other people's posts in your subject. A substantive comment associates your profile with the topic and it is visible to everyone in that conversation, which is a much larger room than your own followers. See Commenting Well, and Why It Beats Posting.

Company content is a starting point, not the post. The version that builds authority adds the thing the original could not have: what you have seen, what surprised you, what you would push back on.

Choosing a Share Copy Option covers picking from the copy your Admin has written, and AI Share Copy covers generating a draft you then make your own. Either way the last edit should be yours.

There is no required ratio of company content to third-party content. A third-party article shared with nothing added builds no authority at all, and a company post you genuinely have a view on builds plenty. What matters is whether the post is recognizably yours and recognizably about your subject.

FAQ

How do I become a subject matter expert on LinkedIn?

Pick a narrow subject you can speak to credibly, make your profile say so, then post and comment inside that subject consistently for several months. There is no shortcut, and there is no setting.

Does it hurt my reach if I post about something off-topic?

A single off-topic post costs very little. A pattern of posting across many unrelated subjects does, because it prevents the platform from forming a clear view of what you are credible on.

Should most of what I share come from outside my company?

There is no required ratio. What matters is whether you add your own perspective and stay recognizably on your subject. A company post with your genuine view on it builds more credibility than a third-party article shared without comment.

What if my job covers several unrelated areas?

Pick the one you most want to be known for. You are choosing what to build a reputation in, not describing your job description.

Where do I find content in my subject?

Your program Admin organizes content into groups by topic, so the group closest to your work is the place to start. See How Your Timeline Works.
