Ask most membership teams how their marketing is performing and you’ll (hopefully) get a confident answer. Website visits are up. Email open rates look healthy. The last few LinkedIn posts did well.

But ask how many of those visits turned into members, or how many members renewed this quarter, and things can get a bit quiet.

MemberWise’s Digital Excellence Report found that 34% of membership organisations saw membership decline, and more than half are struggling with member acquisition and retention. That’s why it pays to look at the numbers others overlook.

Growth isn’t getting easier, but the organisations that understand their numbers will be best placed to find it.

1. You don’t formally track retention

It sounds good to say ‘we recruited 300 new members this year’. But what matters isn’t how many you bring in. It’s how many you keep.

Picture an association with 2,000 members and an 85% renewal rate. It needs around 300 new members each year just to stay the same size.

Want to grow by 100? You actually need closer to 400 new members.

Improve retention to 90%, and that drops to around 300.

The point: acquisition and retention can’t be treated separately. They need to work together.

2. You don’t track the warning signs

Members may be planning to leave long before they actually do. Renewal is when people decide, but disengagement shows up much earlier: emails go unopened, and a benefit that was used every month sits untouched. It’s a widespread problem, with 45% of organisations in the same MemberWise research reporting declining member engagement.

Most organisations already hold this information across their CRM, events and email systems. If you bring it together to spot changes in behaviour, you have time to respond long before the renewal notice lands. That might mean suggesting a relevant event, pointing out an overlooked benefit or simply asking whether someone’s needs have changed.

3. You don’t follow the whole member journey

Digital platforms make the early numbers easy to see: impressions, clicks, cost per click. But a cheap click that never converts is expensive, and a pricier campaign that attracts members who stay for years can deliver incredible lifetime value. You need to track the full path from advert to enquiry, application, membership and renewal. Often the most revealing figure is what it costs to gain a member who stays, set against the value they bring over time.

4. You expect organic marketing to do every job

Organic social, SEO, email and content aren’t interchangeable with paid acquisition, and paid media plays a different role. But ‘let’s run some ads’ isn’t a strategy. Start with the problem, for example ‘we need more early-career members’. The objective should shape the media plan, not the other way round.

Membership journeys are rarely neat. In our upcoming webinar, Seven Scary Membership Stats You Don’t Want to See, we’re looking at the numbers behind membership growth and why it’s slowing for some organisations but not others. We’ll also share a practical framework for building the right digital strategy for your association.
