Every few weeks someone reposts the same advice: never put a link in your LinkedIn post, drop it in the first comment instead. Someone else replies that this is a myth and LinkedIn has said so. Both camps sound confident. Meanwhile you have a case study on your site, a webinar next Tuesday, and no idea where to put the URL.
The honest answer to the LinkedIn external links reach question is not a yes or a no. It is a mechanism. Once you see the mechanism, you can stop reciting rules and start deciding per post.
There is no published rule that penalises links
Start with what we can actually check. LinkedIn has never published a policy saying outbound links are down-ranked. There is no setting, no documented demotion, no number anyone can quote from the company. Every "links cost you 40% of reach" figure circulating on the feed traces back to someone's own sample of posts, measured with no control group, usually by a person selling a course on the algorithm.
That does not mean link posts perform the same as text posts. It means the gap, where it exists, is probably not a hidden punishment. It is the natural consequence of what a link does to reader behaviour and to how the feed ranks what readers do.
So stop asking whether LinkedIn hates links. Ask what happens in the first thirty minutes after you publish one.
The mechanism: links move attention off the platform
The feed ranks posts on engagement signals, and one of the most important is how long people stay with your post. A post with a clickable link gives a share of your readers a clear instruction: leave. They click, they land on your article, and they often do not come back to like or comment. Their attention is spent somewhere LinkedIn cannot measure.
Two things follow. First, the link post collects fewer of the reactions and comments that push it to second and third-degree audiences. Second, it collects less time-on-post. If you have not seen why that second one matters, the piece on why dwell time beats your like count covers it. A link post is almost designed to shorten dwell time: the reader's eye jumps to the blue text and the decision becomes click or scroll, not read.
There is a third, less discussed effect. A preview card takes up space and signals "promotion" to a reader scrolling at speed. People have learned that a card usually means someone wants something. Many scroll past before reading a word.
None of this requires a penalty. A post that gets fewer comments and holds people for four seconds instead of thirty will be distributed less than one that does the opposite. Same algorithm, different inputs.
What link in the comments actually buys you
The trick works like this: write a full text post, say the link is in the comments, then post the URL as your own first comment. The post itself has no preview card, holds attention inside the feed, and tends to earn the engagement that a bare text post earns.
It does, in practice, often produce more reach than the same content with the URL in the body. But count the costs honestly.
You lose clicks. Every extra step loses people. A reader must stop, tap into the comments, find your comment among others, and then click. Your post may be seen by more people and still send fewer visitors to your site. Reach is not the goal. Visits, replies and calls are.
Your comment can get buried. If the conversation takes off, your own first comment slides down under other people's. Readers who arrive two days later never find it. Pinning the comment helps, as does editing the post afterwards to add the link once the first hour of distribution is done.
It is visibly a tactic. Senior buyers have seen "link in comments" a thousand times. In some audiences it reads as careful. In others it reads as someone optimising for the algorithm instead of writing for them. Executive and HR audiences in particular tend to notice.
So link-in-comments is not a cheat code. It is a trade: more impressions, fewer clicks per impression, slightly more friction for the reader. Sometimes that trade is worth making. Sometimes it is not.
When to put the link in the post anyway
There are cases where I would put the URL straight in the body and accept whatever reach follows.
When the click is the whole point. A webinar closing Friday. A live application window. A report you actually want downloaded. Here, five hundred readers with an easy click beats two thousand readers with a difficult one. Reach that produces no action is a vanity number.
When your audience is already warm. If most of the people who see your posts know you, the preview card is not a stranger's advert. It is a resource from someone they follow. Friction costs you more than suspicion does.
When the link is the proof. A client's published result, a public report, a news article you are reacting to. Burying evidence in the comments makes the post feel less credible, not more.
And there is a middle path people forget: post with no link at all, and invite replies. "Comment 'send it' and I'll message you the breakdown." The post stays fully native, the comments fill up, and you get a direct message thread with every interested person, which is worth far more than an anonymous page view. It costs you an evening of sending. That is the price.
How to test LinkedIn external links reach on your own account
Other people's data is not your data. Your audience, your topic and your posting rhythm all change the outcome. Run a small test instead of adopting a rule.
Pick one format of content you publish regularly — say, a short breakdown of a client problem with a link to the full write-up. Publish six of them over six weeks. Three with the link in the body, three with the link in the first comment, alternating so you are not comparing a good month against a bad one. Keep the opening line equally strong in all six; a weak hook will wreck the test faster than any link will, which is why the hook openers that earn the second line matter more than link placement.
Then record three numbers per post, not one: impressions, link clicks, and conversations started (replies, DMs, calls booked). LinkedIn's post analytics give you the first two. The third you track by hand.
What you will usually find is that in-comment links win on impressions and lose on click-through rate, and that the conversations column — the only one that pays — does not always follow either. That column is the one that should decide your policy. If you want the fuller distribution picture, the piece on driving traffic from LinkedIn to your website goes into what to do once the click actually happens.
Reach is not your only distribution channel
The link debate absorbs an enormous amount of attention for what it is: a few hundred impressions either way. Most independents would get more out of their content by sending it to twenty named people than by squeezing another 15% of feed reach out of comment placement.
That is the quiet argument against obsessing over placement. A post is a broadcast. A message to a specific person who has the specific problem the post describes is a conversation. If you want to systematise that side, tools exist — BIZLINKED's Chrome extension, for example, runs in your own browser and LinkedIn session and automatically sends invitations and AI-written messages and follow-ups within limits it sets itself. Be clear-eyed about it: LinkedIn's User Agreement does not allow third-party software or extensions that automate activity, and any account using automation can be restricted, at any volume. That is a risk you choose to accept or not.
What to do Monday morning
Stop treating link placement as a moral question. Do this instead.
This week, publish one link post with the URL in the body and one with it in the first comment. Write down impressions, clicks and conversations for both. Repeat next week with the order reversed.
For anything time-sensitive, put the link in the post. For anything evergreen where you mainly want visibility, try the comment, and pin it.
And for your best piece this month, skip the link entirely. Write the core idea as a full post, and message it directly to fifteen people who you know are dealing with that exact problem. Then compare that against your best link post. The answer will probably settle the debate for you.
