For a brand's community, a platform you own does more than a Facebook group: members aren't distracted, conversations can be organised and found again, and the members, the data and the rules stay yours. Facebook is a terrific tool for brand awareness and advertising, but as the home of a community it decides how your group looks, what members can find and who gets to stay.
4 Roads, a community specialist that had built over 120 communities by February 2020, compared the two then on engagement, member experience, retention, support, search and risk, and found the owned platform ahead on all six. Facebook's features are described as they stood then; Facebook changes its rules every now and then, which is part of the argument.
Isn't everyone already on Facebook?
That is the usual reason for starting a community there: a large following already, on a site that is familiar and easy to use. But having your customers on Facebook doesn't make it the best tool for an engaged community. There, your posts compete with the newsfeed, friends, every other group and page your members follow, and the adverts in the sidebar; on your own platform, everything supports your brand. If you're in a Facebook group, ask yourself when you last saw one of its posts, and when you last engaged with one.
Why do organisation and search matter?
On your own platform you can split the community into categories or sub-groups, so people find the sub-topics they care about, and the more organised the topics, the more interactions flourish. In 2020 a Facebook group couldn't be split this way, and its search went back only 30 days, with results that weren't always accurate: in 4 Roads' view, to steer people into starting new threads rather than finding old ones. Moving to your own platform can bring thousands of good threads that Facebook had buried back to life.
Can a Facebook group look and work like your brand?
Not in 2020. Facebook gave millions of different communities one generic template, and kept strictly to its look, feel and functionality, even in paid groups. Member satisfaction is what drives a community's long-term growth, and on your own platform you can:
- put the community in your website's header and footer, so members move easily between the two;
- match your website's branding and theme;
- add search that brings conversations to light, with your knowledge base in its results;
- separate sub-topics, to narrow interests and lift engagement.
Do members stay longer on a platform you own?
Meaningful conversations make a community harder to walk away from, and turn customers into advocates. Facebook's comment culture favours short, throw-away one-liners, and posts turn over so quickly that good discussions are lost. On an owned platform split into sub-topics, threads on members' exact interests can run for days, weeks or years.
Gamification helps too: badges, titles and leaderboards bring people back, but only if you can tailor them to your members. On Facebook you could give a member a "Top Fan" badge, which brought them nothing extra. 4 Roads' clients have used badges to reward members who win photographic challenges, or whose ideas others find useful, rather than those who talk the most.
Can a community answer support questions?
Yes, and it is one of the biggest reasons to have one. There is often no larger knowledge base about your product than your customers. On a platform that keeps its discussions, people search for threads where others have already solved their problem, and if they find none, they ask and experts answer. This is intelligent self-service: quicker for customers, and it keeps them out of your more expensive staffed support channels.
A rough sum of the saving is cost per support call, times support calls a month, times the deflection rate. At 5,000 calls a month and £10 a call, support costs £50,000 a month; deflecting a fairly conservative 30% to the community saves £15,000 a month, not counting equipment, training and overheads. Deflection depends on the community's quality, and some of 4 Roads' clients exceed 65%.
It only works if people can find the answers. In a Facebook group, old conversations could be found only by scrolling back through the feed, and knowledge articles couldn't appear in its search. With 61% of the 5,000 people Microsoft surveyed in 2018 having switched brands because of poor customer service, that costs customers as well as money.
Does a Facebook group help your search rankings?
Not in 2020, when Facebook groups couldn't be indexed, so search engines couldn't show their content or send traffic to it. On your own site, members keep adding pages and engaging with content; Google notices and ranks the site higher, and people searching for the same questions land on your pages, so new customers cost less to win. It would take a team of marketers dedicated to SEO and content to produce what a community produces on its own.
What are the risks of building on Facebook?
When you don't control the tools, you inherit their risk. Brands that spent thousands of hours on Facebook pages saw organic reach cut to around 1%; by 2020 pages with well over 1,000,000 likes commonly struggled to get 100 likes on a post. Groups' reach wasn't restricted then, but Facebook's history shows a pattern: "help us grow Facebook, then we'll charge you for it".
Groups were already changing. In 2019, admins reported members being moved out of groups to an "invited" list for not being active, though many members are passive: they read, and learn from peers and experts. Whatever Facebook's reason, someone else decides who stays in your community.
Nor do you own your members' data: a group with more than 250 members gets an aggregated report. So you can't bring members to your other channels, your protection if Facebook closes the group without warning, or connect the group to your CRM to personalise your marketing and spot members likely to leave. On your own platform you control the functionality, the data, the experience and the advertising space, and the risk doesn't move at another business's whim.
So where does Facebook fit?
Every social platform has a place; the trick is finding the right job for each. Facebook builds awareness and carries advertising. For a community, the best long-term home is a platform where you have full control: be wary of relying on Facebook for any long-term strategy, and more so as the backbone of your community.
