What the rules here come from

LinkedIn Help, post and share updates for the 3,000 character post limit.

The posts on this page follow the same rules the tool runs.

The short answer

LinkedIn Help no longer has a page on hashtags. A hashtag on LinkedIn labels the topic of a post. Do not expect it to bring reach.
Pick hashtags your buyers follow at work: the industry, the role, the method. Not the mood of the post.
Every hashtag here is one word. A phrase is joined in CamelCase, like #ColdEmail, so it stays easy to read.
LinkedIn publishes no number to use. We suggest 3 to 5 per post: one branded, two industry or role, one topic.

What do LinkedIn posts with good hashtags look like?

Eight B2B ads from the Selzee gallery, each set as a LinkedIn company post with a caption from the ad's own words and hashtags written to the same rules the tool runs. Under each: how many hashtags it carries.

The Strategic Media audio advertising ad as a LinkedIn post, with hashtags for podcast advertising and media buying — Strategic Media Inc., 5 hashtags.

The AITHIMETRY AI governance ad as a LinkedIn post, with hashtags for AI governance and risk management — AITHIMETRY, 5 hashtags.

The Codersy fast store ad as a LinkedIn post, with hashtags for ecommerce development and site speed — Codersy, 5 hashtags.

The Yousquared AI secretary ad as a LinkedIn post, with hashtags for real estate agents and proptech — Yousquared, 5 hashtags.

The Quinn Marketing service business ad as a LinkedIn post, with hashtags for lead generation and small business marketing — Quinn Marketing, 5 hashtags.

Where do hashtags work on LinkedIn?

In the post text. Type # and the word, usually on the last line. That is where a reader sees what the post is about.

LinkedIn Help used to have a page on hashtags. On 28 October 2026 that page gave a 404, and no other LinkedIn Help page explains how hashtags work today. So we do not repeat old rules about hashtag feeds or comments.

Hashtags count toward the post. A LinkedIn post holds up to 3,000 characters, and every hashtag uses part of that. Five short hashtags take well under 100.

Which hashtags fit which LinkedIn post?

Start from the post type, then make it yours. The example hashtags are made up to show the shape; the tool writes from what you paste, never from these.

Post	Start with	What the hashtags name	An example
Company update	Branded, then industry	Your company, your market, the topic of the update	#Mailbridge #EmailDeliverability
Hiring post	Role	The job, the team, the place	#Hiring #SalesJobs #RemoteJobs
How-to or lesson	Method	The method or skill the post teaches	#ColdEmail #SalesProspecting
Event or webinar	Event name	One hashtag for the event that every post reuses	#RevOpsSummit2027
Customer story	Industry	The customer's industry and the problem you solved	#Logistics #SupplyChain

How many hashtags should a LinkedIn post have?

LinkedIn does not publish a number, and the post limit leaves plenty of room. The limit that matters is the reader: a line of 15 hashtags at the end reads as a list, not a post.

We suggest 3 to 5. One branded hashtag you reuse on every post, one or two for your industry or role, and one for the topic of this post.

The tool returns up to 12 in groups, specific first. Click the ones you do not want and copy the rest.

How do you use the LinkedIn hashtag generator?

Paste your post

Or say in a sentence what it teaches, announces or asks.
Add your company

Optional, under "More details". Only then do you get branded hashtags.
Pick and copy

Click a hashtag to leave it out. Copy all puts the rest on your clipboard with spaces.

How do you pick hashtags your buyers follow?

Name the trade, not the feeling

#SalesProspecting reaches sellers. #Grateful reaches no buyer in particular.

Reuse one branded hashtag

The same one on every company post ties your posts together under one name.

Match the reader's job title

Write the hashtag the way your buyer names their own work: #RevOps, #Procurement, #HRTech.

Put them in the post

Not in the first comment. The reader sees them with the text they label.

Skip the reach tags

Tags like #motivation or #success name no topic. The tool never returns them.

Search it first

Search the hashtag on LinkedIn before you post. If the posts that come up are not from your buyers, pick another.

LinkedIn hashtag generator: FAQ

Do hashtags still work on LinkedIn?

They still link in a post, but LinkedIn no longer documents how they work. Its help page on hashtags gave a 404 on 28 October 2026. Use a few to label the topic, and do not count on them for reach. When the post should become an ad, Selzee makes the ad from your site.

How many hashtags should I use on LinkedIn?

LinkedIn gives no number. We suggest 3 to 5: one branded, one or two for the industry or role, one for the topic. The tool returns up to 12 so you can pick. For ads that speak to the same buyers, start free with Selzee.

Where do I put hashtags in a LinkedIn post?

In the post text, usually on the last line. Type # and the word with no space. When the company page needs ads too, Selzee can make them on brand.

Should I put LinkedIn hashtags in the first comment?

No. Put them in the post, where the reader sees them with the text. LinkedIn publishes no rule that a comment hashtag helps a post. For ads that carry the same message, paste your site URL into Selzee.

Can a LinkedIn hashtag have spaces?

Keep it one word with no spaces. This tool joins every phrase into one word, like #ColdEmail, and drops punctuation. When you want ads behind the posts, start free with Selzee.

Is this LinkedIn hashtag generator free?

Yes. No account, no email and no card. Each visitor can run it 3 times a day, so the shared AI model stays available for everyone. When you want ads as well, start free with Selzee, no card needed.

How we checked

Last checked: 28 October 2026. The post length comes from LinkedIn's page on posting. LinkedIn's help page on hashtags gave a 404 that day, so this page states no LinkedIn rule on hashtags.

This tool runs the same engine as our Facebook hashtag generator. Its clean rules were worked by hand: a phrase joined in CamelCase, a leading # kept once, two hashtags on one line cut to the first. The code agrees with every one.
The code drops repeats, generic reach tags such as #motivation and #success, and any branded hashtag that does not contain the company or name you typed. With no name, there is no branded group.
The set is capped at 12 hashtags and 30 characters each, specific first, so the broad ones are dropped first when the model writes too many.
Typical, boundary and hostile inputs ran through the real page with the model reply stubbed: an empty form, a one line post, a non-English post and an instruction typed into the post box.
The model reply was stubbed in every test on this page. We did not grade live samples for this release.
