Key takeaways
- The LinkedIn hashtag generator turns a topic or caption plus a niche into several hashtag sets you can edit.
- Hashtags count toward LinkedIn’s 3,000-character post limit, so they belong at the end of the post.
- LinkedIn shows roughly 210 characters on desktop and about 140 on mobile before “...see more”.
- A useful set mixes specific, niche, broad and branded tags and leaves out anything unrelated to the post.
- The tool is free and needs no sign-up; your input goes to our AI model to write the tags and isn’t stored.

How does the hashtag generator work?
- Describe the post. Paste the caption or write the topic in a line, then add your niche.
- Get a few options. The generator returns several hashtag sets written for LinkedIn.
- Choose and adjust. Take the set that fits best, change any tag you want, and paste it into your LinkedIn post.
How do hashtags fit into LinkedIn’s character limit?
Every hashtag counts toward the 3,000 characters a LinkedIn post can hold. Put them on the last line, after your text, so they never push your opening lines down behind “...see more”.
To see how many characters a draft uses with the tags included, paste it into the LinkedIn Character Counter.
Which LinkedIn formats can you add hashtags to?
Text post
A text post holds up to 3,000 characters. Your opening has to work before the fold, which comes at roughly 210 characters on desktop and around 140 on mobile.
Document carousel
You upload a PDF and LinkedIn shows it as slides that readers swipe through. Pages are 1080 px wide and can go as tall as a 4:5 portrait shape.
Image post
Use 1200 x 627 for a horizontal picture or a portrait shape up to 4:5. One post takes up to 20 images, each up to 10 MB.
Article or newsletter
Long-form writing published on LinkedIn, with a headline of up to 100 characters.
How do you choose hashtags on LinkedIn?
Pair a couple of wide tags with a few narrow ones that say what this exact post is about. Delete any tag the post doesn’t deal with, even if it is popular.
When you post in one niche week after week, keep a small group of tags you reuse on every post and add one or two that change with the topic.
What kinds of hashtags does the generator suggest?
| Type of tag | What it does |
|---|---|
| Specific | Names the subject of this one post |
| Niche | A tag the people in your field follow or search |
| Broad | One or two wide tags for the general topic |
| Branded | A tag that belongs to you, your company or your series |
A set rarely needs all four kinds. A post about a hiring lesson could carry one specific tag, one niche tag and one broad tag, and stop there.

What should you do after the post is live?
Good tags and a clear opening help the right readers find the post. Reactions from real people are a separate signal, and LinkedIn reads them in the first hours after you publish.
LinkedInLikes is a free community where members react to each other’s posts by hand from their own LinkedIn accounts. You paste the link to your post and spend points on likes; you get points by liking posts from other members. Ask members to react to your LinkedIn post.
