Top 10 Largest Linkedin Groups

by Jake on April 17, 2012

The power of groups on Linkedin should never be under estimated as it is one of the most powerful networking tools available on the site. There are well over 1.2 million groups on Linkedin so that gives you a fairly large field to play in although do remember, you are limited to joining 50 only. Due to this it is a good idea to choose wisely depending on what it is you are looking to gain from Linkedin.

If you are looking to find sales leads or hunt talent for clients or company, then it is beneficial to join the right groups that are relevant to your industry. It also helps massively if that group has a huge number of members rather than just a couple. Not that small groups are pointless, far from it. A small but highly targeted or niche group that suits your game plan is still worth engaging with.

If you bring up the groups option on Linkedin you will find that just about every conceivable niche is represented, so you should be able to find a few that are relevant to you.

A great reason to be in a large group is also the networking potential if you are looking to grow your 1st degree contacts. Now don’t go spamming people at random as this will simply get you a restricted account in no time. I get invites all the time claiming that we worked or have done business together. It’s a clear lie to try and get into my network and at best I’ll click ignore, but if someone pushes their luck I will report as spam.

But if you honestly want to network, then there is nothing wrong with making a connection and saying hi, we are both in XYZ group and I thought it might be beneficial to connect as we have a shared interest. You are far more likely to get an acceptance this way. Also, if you engage in the community discussions regularly with quality and relevant insights, then you will really boost your chances of the target person accepting your invite.

So which groups are the biggest and how many members are in them? Well let’s take a look at the top 10.

Now I’ll be honest, if you apply some advanced Boolean logic to the group members here you will find a lot of them contain a lot of recruiters and HR professionals. But they are still huge groups and depending upon your Linkedin strategy will give you access to a vast number of people to connect with and leverage off their connections.

So take a look and play around with the group function. Use it correctly and you can really start to network like a champion. Do a search for industry. Maybe you are into digital marketing or social media? Search the groups for those keywords and see which are the largest that get returned and join them.

As a final note though, size doesn’t always mean better with Linkedin groups. Some markets are naturally small or you may find a smaller group that has a high engagement of its users. This is a good thing. Take a look at the discussions and see how well they are moderated. If it’s all spam then maybe use it to quickly network then get out and join another. If its high quality content being discussed, join in and make your mark.

Good luck and let me know how it goes.
