Type @ followed by the person's or company's name while writing a post, comment, or article, then select them from the dropdown. The name must be selected from the suggestion list to create an active tag.
Tagging notifies the person and can extend your reach when they engage. Only tag people genuinely relevant to the post. Over-tagging looks spammy and can trigger LinkedIn's engagement-bait filter, reducing your reach.
| Surface | Tagging Supported | Where to Type | Notes | Tag Limit |
|---|---|---|---|---|
| Feed Posts | Yes | In the post text body while composing | Most common tagging surface. Tags appear as blue clickable links in the published post. | No hard limit, but 1 to 3 is the etiquette maximum |
| Comments | Yes | In any comment field below a post | Tagging in comments notifies the person and can draw them into a conversation. Useful for introducing two connections. | No hard limit; 1 to 2 per comment is standard |
| LinkedIn Articles | Yes | In the article body text during editing | Tags in articles send a notification when the article is published. Good for crediting sources or collaborators. | No hard limit in the article body |
| Image Captions | Yes | In the caption/description field when uploading a photo | Different from tagging someone in a photo face-tag. Caption tags work the same as post body tags. | Same etiquette rules as post body |
| Photo Face Tags | Yes | In the photo editor after uploading an image | Tag people directly on their face in a photo. The tagged person must accept the tag. Only available on photos, not documents or videos. | Up to 30 people per photo |
| Direct Messages | No | Not available in DMs | You cannot tag someone with @ in a direct message. Use their name or mention them in a post instead. | N/A |

Why is my LinkedIn tag not working?
The most common reasons a LinkedIn tag fails to work: the person's privacy settings block mentions from non-connections, you are not connected to them and their profile is set to connections-only for tags, you typed their name but did not select from the dropdown (the name must be selected from the suggestion list, not just typed), or the person has changed their name recently and the old name no longer matches. If the @ dropdown does not appear after typing at least 3 characters of their name, try their exact full name as it appears on their profile.
Can you tag someone on LinkedIn without being connected?
Yes, in most cases. LinkedIn allows tagging by default for all members, not just first-degree connections. However, individual users can restrict who can mention them in their privacy settings. If someone has restricted mentions to connections only, you will not be able to tag them unless you connect first. If the dropdown shows their name but the tag does not send a notification, they may have turned off mention notifications in their settings.
Does tagging someone on LinkedIn notify them?
Yes. When you tag someone in a post or comment, they receive a LinkedIn notification saying '[Your name] mentioned you in a post.' They also receive an email notification if they have email alerts enabled. Tagging a company page sends a notification to the page admins. This is why over-tagging is disruptive and considered poor LinkedIn etiquette: each unnecessary tag creates an unwanted notification for the person being tagged.
Does tagging boost reach on LinkedIn?
Tagging can modestly extend reach when the tagged person engages with the post (likes, comments, or shares it), because that engagement is then surfaced to their network. However, LinkedIn has reduced the reach amplification from tags over time to prevent abuse. Mass-tagging (5 or more people per post) can actually suppress reach because the algorithm classifies it as engagement-bait, which is a negative quality signal. The safest approach: tag 1 to 3 genuinely relevant people and let the post earn its reach through content quality.
The most sustainable way to grow your LinkedIn reach is through consistent, relevant content that earns genuine engagement. Creators who use Lifast build their audience through post quality and cadence, not tag volume, which means their reach compounds without algorithm penalties.
LinkedIn's algorithm evaluates tagging behavior as part of post quality scoring. Here is what the data and creator experience tell us.
| Tagging Pattern | Algorithm Response | Outcome |
|---|---|---|
| 1 to 2 genuinely relevant tags | Neutral to positive | Normal or slightly boosted distribution if tagged person engages |
| 3 relevant tags | Neutral | No penalty; tagging benefit depends on tagged users' engagement |
| 4 to 5 tags, mixed relevance | Beginning of engagement-bait detection | Possible slight suppression; tagged people unlikely to engage |
| 6 or more tags | Engagement-bait flag triggered | Post reach reduced; may be shown to fewer people in the feed |
| Repeated tagging of same people | Spam signal accumulates over time | Account-level reach reduction possible; tagged people may mute you |
Tags and hashtags are both used in LinkedIn posts but they work differently. Understanding the difference helps you use both correctly.
| Dimension | @ Person or Company Tag | # Hashtag |
|---|---|---|
| How to use | Type @ then the person's name | Type # then the topic keyword |
| Who sees it | Tagged person is notified; their network may see it if they engage | Feeds of people following that hashtag |
| Reach mechanism | Tagged person's network via their engagement | Topic-based discovery |
| Algorithm treatment | Engagement-bait trigger at 5+ tags per post | Minimal reach impact since 2023 algorithm update |
| Best use | Credit collaborators, reference sources, announce partnerships | Very low-priority; 1 to 3 niche hashtags maximum |
| Notification sent | Yes, to the tagged person | No notification |
| Abuse penalty | Mass-tagging suppresses post reach | Hashtag spam reduces distribution |
These are the specific situations where a well-placed tag produces genuine relationship value and reach extension.
Announcing a partnership or collaboration
Tagging the partner company and the individual you worked with on a partnership announcement is one of the highest-ROI tag situations. Both parties have strong motivation to engage and share, extending reach into their combined networks.
Example phrasing
"Excited to announce our new integration with [Company Tag]. Thanks to [Person Tag] for making this happen over the last 3 months."
Sharing a client result (with permission)
Tagging a client when sharing their transformation story gives the post authenticity and often motivates the client to share it with their own network, providing free distribution to an entirely new audience.
Example phrasing
"Sharing this with permission from [Client Tag]: 12 months ago they came to us with a 40-day sales cycle. Today it is 11 days."
Crediting a source or insight
If a post was directly inspired by something someone else shared or said, tagging them is both courteous and strategically useful. Most people engage when credited, and the engagement extends reach.
Example phrasing
"[Person Tag] said something in a conversation last week that completely reframed how I think about onboarding. Here it is:"
Event recap posts
Tagging the event organizer and one or two people you met at an event creates a reason for multiple parties to engage, comment, and share, all of which benefit the post's distribution.
Example phrasing
"Just wrapped [Event Tag]. Three things I took away that are changing how I think about B2B GTM this year:"
Podcast or content feature
When you are featured on a podcast or in someone else's content, tagging the host is expected etiquette and produces mutual benefit: both parties' audiences are introduced to the other.
Example phrasing
"Had a great conversation with [Host Tag] on [Podcast Tag] this week about why most LinkedIn strategies fail in month two."

When a tagged person engages with a post, that engagement gets surfaced to their network, effectively extending the post's reach into a new audience segment. This is the legitimate reach benefit of tagging. A well-placed tag on a post that the tagged person finds genuinely relevant produces meaningful secondary distribution. A tag on a post the person finds irrelevant produces nothing, because they do not engage.
The math of tagging is simple: one tag on a post that resonates with the tagged person is worth more than ten tags on a post that feel random to everyone tagged. Quality of relevance determines the value of a tag, not quantity. A founder who tags the CEO of the company they just partnered with on an announcement post will see real reach extension. A founder who tags ten LinkedIn influencers on an unrelated post will see the algorithm flag the post as low-quality.
The best-performing tagged posts share a common structure: the post is primarily valuable without the tags, the tags are to specific people who are genuinely relevant, and the tags are mentioned naturally in the text. 'I had a great conversation with [tag] this week about enterprise sales cycles' works. 'Great post, tagging in [tag][tag][tag][tag][tag] because they should see this' reads as spam to both humans and the algorithm.
Company page tags work slightly differently from personal profile tags. When you tag a company page, the notification goes to the page's admin team rather than an individual. Company page admins can then re-share or engage with the post from the company account, which can distribute your post to the company's entire follower base. For B2B founders and marketers, this makes company tags on partnership announcements, case studies, or event recaps potentially very valuable.
Personal profile tags and company page tags can be combined in the same post. A post about a completed project might tag the client company and the individual you worked with directly. Both receive notifications and both can engage, potentially doubling the secondary reach of the post across two separate audiences.
One important distinction: company tags require searching for the exact company name and selecting the official page from the dropdown. Typing a company name without selecting it from the dropdown will not create a functional tag or send a notification. Always confirm the blue hyperlink appears in the post preview before publishing.
LinkedIn's top content creators tag sparingly and intentionally. The unofficial standard among professional LinkedIn users is a maximum of 3 tags per post, used only when the tagged person is directly referenced in the content. Creators who maintain this standard see higher engagement rates because their tags produce genuine interactions rather than annoyed dismissals.
A useful rule: before tagging someone, ask whether you would tag them in a text message about the same topic. If the answer is yes, the tag is appropriate. If the answer is 'not really, but I want them to see this,' the tag is not appropriate. Tags that feel intrusive damage the relationship with the person being tagged and signal low quality to the algorithm.
The best use of LinkedIn tags builds relationships. Tagging a collaborator on a shared success post, a mentor on a lesson-learned post, or a client on a result post (with permission) creates a positive notification for the tagged person and a genuine reason for them to engage. These engagements compound into long-term visibility and relationship capital.
The golden rule of LinkedIn tagging: only tag someone if you would be comfortable calling them to say you mentioned them publicly. If the answer is yes, the tag is appropriate. If it feels like a stretch, skip it. Your reputation is worth more than one post's incremental reach.
Everything you need to know about tagging people and companies on LinkedIn.
Type the @ symbol while writing a post, comment, or article, then immediately type the person's name. A dropdown suggestion list will appear. Select the correct person from the dropdown to create an active tag. Their name will appear as a blue hyperlink in the post. If you type the name without selecting from the dropdown, no tag is created and the person receives no notification.
If the dropdown does not appear, try these fixes: type at least 3 to 4 characters of their exact name as it appears on LinkedIn, check that their privacy settings allow mentions (some users restrict this to connections only), verify you have a stable internet connection (tag suggestions require a live API call), or try refreshing the page and starting the post again. If you are tagging a company page, search for the exact official page name.
LinkedIn does not publish a hard technical limit on the number of people you can tag in a single post. However, LinkedIn's algorithm is known to reduce the reach of posts that use 5 or more tags because it classifies them as engagement-bait. The practical maximum for professional etiquette and algorithmic health is 1 to 3 tags per post, used only for people directly referenced in the content.
By default, yes. Anyone on LinkedIn can tag you in a post or comment, and you will receive a notification. You can control this in Settings and Privacy under Visibility. You can restrict mentions to first-degree connections only, or turn off mention notifications entirely. You cannot retroactively remove a tag someone else added to a post, but you can report the post or ask the author to remove it.
Tagging can help reach when the tagged person engages with the post, because that engagement is then shown to their network. The reach benefit depends entirely on whether the tagged person finds the post relevant enough to engage with it. Over-tagging (5 or more people) triggers LinkedIn's engagement-bait classifier and can suppress the post's reach. One to three genuine, relevant tags on a post the tagged people will actually engage with is the approach that produces real reach benefits.
Yes. After uploading a photo in a post, you can tag people directly on their face in the image using LinkedIn's photo tagging feature. Click or tap on the person's face in the photo editor, then search for their name. The tagged person will receive a notification and must accept the tag for it to remain visible on their profile. Photo face-tagging is separate from @ tagging in the post text body.
