Forums provide the opportunity to build an online community that allows your audience to connect in a place where they know their interests are shared. This sense of connectedness is more important than ever in a time where more work, communication, and socialization is being done online.

Online communities are particularly beneficial for businesses because they allow customers to interact with each other in a smaller circle than they could via social media, which increases engagement and brand affinity.

For instance, let's say one of your customers has a very unique problem with your product or service, and posts about it on your forum. That post is much easier to find than it would be on social media, where millions of users are talking about a million different things.

Even better, maybe another forum user has faced that same problem and can answer their question before your service reps even see it.

There is an incredible amount of value in reaching and building your community using a forum. Here, we're going to explore the best forum software to get you started.

Ways to Build Your Community Using Forum Software

People notice when brands listen to and converse with their customers, and they especially notice when brands foster their own communities. How? Through the power of word-of-mouth marketing. Customers who view themselves as valued members of your community are much more likely to talk about your brand to their friends.

Here's how you can build a strong community using your forum software.

1. Spread the word.

Nobody will join your online community if they don't know it exists. Spread the word about your new forum by including CTAs to join your forum in email newsletters or social posts. Ask your brand ambassadors or loyal fans to start posting about the forum, and post content on the forum so when other users join, you already have an established presence on the channel.

2. Listen to and check on your community regularly.

Reviewing your forum and responding to what your audience has to say is a crucial part of community building. Your customers are far less likely to continue to interact and engage on your forum if they feel as though they are being ignored. Responding to their feedback shows your users that you value their opinions and care about their experiences with your product.

Additionally, it's your job to make sure everything is running smoothly on your forum. Checking on your community regularly will help you dissolve any service escalations, and give people the support they are seeking.

3. Foster a helpful discourse.

A forum should be a safe place for your customers, prospects, employees, fans, and audience to interact, ask, and answer questions. By establishing a helpful ethos early on, or creating community guidelines that prioritize patience and kindness within responses, your community will grow without the need to constantly monitor it 24/7.
