Growing membership is a crucial focus for many associations, especially following thee decline seen over the last few years.
One of the most effective ways to achieve this is by using social media to grow association membership. No matter who your ideal association member is, they are almost certainly active on at least one platform.
Here are six updated strategies for 2025 to help you use social media to grow your association’s membership.
Before diving in, make sure to research your audience to ensure you are choosing the most effective platforms and tailoring content accordingly.
1. Make Social Media Part of Your Membership Engagement Strategy
A common mistake made by associations is using social media solely for announcements or sales. Instead, social media should be a fully integrated part of your year-round omnichannel engagement strategy.
Rather than focusing engagement only around your annual event, aim to provide regular, valuable content throughout the year. This approach helps build stronger brand presence and fosters deeper relationships with both prospective and current members.
2025 Insight: Include newer platforms like Bluesky, Threads and Mastodon in your strategy to reach different segments, especially those involved in academic or scientific communities.
2. Run Social Media Ads to Attract New Association Members
Paid social ads are an excellent way to connect with potential members. Most major platforms, including LinkedIn, Facebook, and now Threads, allow targeting by profession, interests, and other relevant criteria.
Having accurate audience data before running campaigns ensures that you are using social media to grow association membership effectively, not just increasing visibility.
3. Use Hashtags to Expand Your Association’s Social Reach
Hashtags are still essential in 2025. They are essential in growing association membership through social media by increasing discoverability and your post`s visibility. They also help you connect with audiences interested in specific topics, even if they don’t follow your page yet.
Example: Use hashtags like #CardioResearch or #ClimatePolicy to attract professionals already engaged in those discussions.
Tip: Combine niche, high-relevance hashtags with broader, high-traffic ones to maximise exposure without losing focus.
4. Tag Influential Profiles to Grow Membership Visibility
Tagging remains a smart strategy for increasing reach and credibility. You benefit from your post being seen by others’ followers, and the association gains social proof via connection.
- Your association’s post will reach the tagged user’s followers (i.e. a larger audience)
- Your association will be viewed with higher authority by users through a connection with someone they already follow
By tagging others in your social media posts, you can usually find new potential members who are ready to trust and engage with you right from the start.
Not sure whom to tag or when to tag them?
Who to tag:
-
Speakers from recent or upcoming events
-
Event attendees or volunteers
-
Sponsors and collaborators
-
Peer associations and researchers
Tagging adds social proof and can help you use social media to grow association membership via trusted connections.

5. Encourage Member Advocacy on Social Media Platforms
Your current members are often your best advocates. While your own posts are informative, peer endorsements carry much more persuasive power.
Make it easy for members to share: provide pre-written content, branded images, and hashtags. A member toolkit can streamline this process and increase uptake.
“I joined [Association Name] last year and have gained so much from the community and resources!” , this kind of authentic post can convert hesitant prospects into loyal members.
Tip: Make promoting your association on social media as easy as possible for your members by creating a toolkit of existing image assets and copy snippets that they can use online. This is a great way to organically increase association membership via social media.
6. Join Industry Conversations to Promote Association Membership
Find out where your ideal members are having discussions online, and be there. Monitor relevant hashtags, news trends, and influencers to see what topics are trending in your sector.
Engage when you have something insightful to say. Sharing valuable perspectives or resources positions your association as a thought leader and draws in professionals aligned with your mission.
2025 Watchlist: Conversations are expanding to decentralised networks like Mastodon and Bluesky. The latter is particularly prominent in scientific circles and may soon surpass traditional platforms like X (formerly Twitter) for academic engagement. Participating there can boost awareness and help grow association membership through social media.
