To find LinkedIn groups, type a keyword into the search bar on your homepage and filter the results to Groups, then click Request to join on any group you like. To leave one, go to your Groups homepage, click the More icon beside the group's name and choose Leave this group. LinkedIn caps you at 100 groups.
LinkedIn groups don't get the attention they did a few years ago, which is exactly why a good one can still be useful. A focused group of buyers, peers or people in your local area is a quieter room than the main feed, and quieter rooms are where questions get answered.
Here's how finding, joining and leaving work, according to LinkedIn's own help pages, and the limits that decide how many you can sensibly use.
How to find LinkedIn groups
LinkedIn gives you two routes:
- Search: type a group name or keyword into the search bar at the top of your homepage and choose the Groups option.
- Recommendations: LinkedIn suggests groups based on the companies, schools and industries you share with other members.
If LinkedIn shows you no recommendations, its help page lists the usual reasons: you've already joined or requested all of them, they've been removed, none are available right now, or your profile is missing current or past company, school or industry details. That last one is the easy fix. Fill in your experience and education and the suggestions improve.
How to join a group
- Open the group's homepage from search or your recommendations.
- Click Request to join.
- Wait for approval, or answer any questions the group's managers ask.
You can also join by accepting an invitation from a member or manager. On the mobile app, LinkedIn's steps are to search for your keywords, filter the results to Groups, open the group and tap the join button.
Approval is up to the group. LinkedIn says managers may review your request or ask for more information, so a sensible headline and a filled-in profile help.
Changed your mind? Withdraw the request
If a request is still pending and you'd rather not join after all, LinkedIn says to go to the Requested tab on your Groups homepage and choose Withdraw. Pending requests count towards one of the limits below, so it's worth clearing out the ones that have sat there for weeks.
How to leave a LinkedIn group
- Go to your Groups homepage.
- Click the More icon beside the group name.
- Choose Leave this group.
- Click Leave in the pop-up to confirm.
The mobile app follows the same pattern: Groups homepage, the More icon next to the group, the leave option, then confirm. One exception from LinkedIn's group management help: an owner can't leave until another owner has been added to manage the group.
The LinkedIn group limits
These are the numbers LinkedIn publishes on its general limits page, and it says it can't currently raise them:
| Limit | LinkedIn's number |
|---|---|
| Groups you can belong to | 100 |
| Groups with a pending join request | 20 |
| Groups you can manage | 30 |
| Groups you can create per day | 5 |
| Owners per group | 10 |
| Managers per group | 20 |
| Posts in a single group each week | 15 |
| Groups you can post in each week | 20 |
| Total posts across all groups (LinkedIn lists this cap without a period) | 60 |
| Characters in a group post | 3,000 |
| Characters in a comment | 1,250 |
If you hit the 100 cap, you'll have to leave a group before you can join another. If you're posting, the weekly caps matter more: 15 posts in one group a week is plenty, and anyone posting more than that is probably being skipped by the members anyway.
If you run a group yourself
The same limits page covers the other side. A group can have up to 10 owners and 20 managers, and it can hold up to 3 million members. Admins can send up to 50 message requests a day to members of their group they aren't connected to, and you can delete up to 30 groups a day if you're tidying up old ones.
Spread the management load. If you're the only owner, remember the rule above: you can't leave until someone else is an owner too. Add a second owner you trust while things are calm, not on the day you want to step away. A couple of active managers keeps a group alive when you're busy with clients, and it means nobody's waiting days for a join request.

Getting value from the groups you keep
Treat a group like a room at an event. Read for a week before you post, answer questions before you ask any, and never drop the same link into ten groups in one afternoon. The weekly posting caps are LinkedIn's way of saying the same thing.
Groups also sit alongside your network rather than replacing it. If someone useful turns up in a group, my guide on how to message someone on LinkedIn covers reaching them before you're connected, and what 3rd means on LinkedIn explains why some members are harder to reach.
My advice
Join fewer groups, not more. Pick three or four where your buyers or peers gather, turn up regularly, and leave the rest. The 100-group cap is a ceiling, not a target, and a tidy Groups homepage makes it far easier to spot the conversations worth your time.
