If you just starting to set up your Facebook group now, make sure its set as public. If your group is public, Facebook starts automatically make it visible, it will show up in search results and more people can find it.
Second, make sure you know your target audience really well. The better you can picture the specific type of group member you are targeting, the better your messaging will be because you will be speaking directly to them.
Third, make sure you can clearly and concisely communicate why someone should take time out of their busy schedule to join your group and participate in your group. There has to be a compelling reason so your messaging pops. Once you have a set, you will want to optimize your group name and description.
Pay attention to group description
You want to increase the changes that when your group shows up in a search on Facebook that the name and the description immidiately tells people what is it about. With the description, pay close attention to the first 60 characters because only the first 60 characters show up in the initial search results. So you dont want to waste any of those 60 characters with the word “welcome” or spelling out the full name of the group when the full name is already in the name. Just get streight to the point about what your group is about, so you can convince ppl right then and there.
Of course, some people will click on the link to read the full description before making a decision so make sure that full description is awesome too.
Invite your business page fans
You may already know how to invite your personal Facebook friends to join your group, but you can also invite your business page fans as long as your business page and your group are linked. To do this, you need to make sure that Groups shows up in your navigation bar on your business page.
Click on More and then Groups. If it does not show up there, go to Edit Tabs at the bottom of that dropdown menu, scroll down till you get to Groups and make sure Groups is toggled on. Once you have done that, go back to your business page, click on More and then Groups. And if your grop has already linked to your page, you will see it here and you can click on invite, and the people who like your business page will show up and then you can invite them.
If your group is not yet linked to your page, click on Link Group, any any groups you are an admin of will shop up for you to Link.
Remember that as time goes on, you will get more and more fans to your business page, so there will always be opportunities to invite new people to join your group.
First, think of all the normal emails you just send throughout the day. If a lot of the people you email are the types of people you would want to join your group, then consider having a promotion for your Facebook group in your email signature.
Simply add a line of text at the bottom of your email signature and make sure that line of text is punchy so people want to join you.
Now lets say you also have an email list of subscribers of people you send email blasts out to. And a lot of these subs would make for great group members. Send out an email blast to your subscribers, telling them about the benefits of joining the group and have a big button in the middle that people can click on so they can go straight to the group and join.
You can also invite your brand new email subscribers to join your group if they happen to receive a welcome email when they subscribe to you.
Remember that these people are already in the mindset of warming up to you, so your invitation to join your Facebook group just gives them another chance to get into your world.
Plus, promote your group on your website in the articles, use pop ups, share your group in all social media platforms you have.
