Selecting the Right KPIs

With so many potential metrics to track, how do you determine which ones to focus on? Follow these steps:

1. Identify your key goals

Start by getting clear on your core objectives. Are you laser focused on revenue generation or user acquisition in the early stages? Hypergrowth or stability? High member engagement or passive content consumption? Your priorities will dictate which metrics matter most.

2. Consider leading vs. lagging metrics

Leading metrics like traffic and leads predict future growth. Lagging metrics like revenue describe past performance. Focus on enough leading indicators to forecast momentum.

3. Establish your benchmark baselines

Research benchmarks for your industry to determine realistic goals. Comparing against competitors can provide additional context.

4. Determine your measurement cadence

KPIs should align to key business cycles. Monthly or quarterly works for most, but shorter intervals may be needed for highly dynamic metrics.

5. Build processes and systems to track

Automate tracking through analytics and BI tools as much as possible. Establish processes for regularly monitoring your target metrics.

6. Distill into a focused dashboard

Don’t get overwhelmed with too many metrics. Pare down to a core KPI dashboard you can quickly scan for insights on priority goals.

Using Metrics to Grow Your Membership Site

Simply tracking KPIs doesn’t guarantee success. You need to consistently analyze results and make strategic changes based on what the numbers reveal. Here are some examples of optimizing growth through key metrics:

  • If traffic volume is low, test new lead generation strategies such as content upgrades, SEO improvements, or social media campaigns.
  • If conversion rates are poor, redesign your signup flow to reduce friction, build trust through social proof, and clearly communicate membership benefits.
  • If churn is high, survey members and identify pain points that may be causing cancellations, then address them.
  • If engagement is declining, experiment with new community features, discussion topics, and live events to reinvigorate participation.
  • If revenue is stalling, model the impact of price changes, new paid tiers, or additional products/services to sell.

Rinse and repeat – continuously track metrics, hypothesize improvements, test changes, and monitor the numbers to guide your strategy. Over time, you gain greater clarity into what levers drive growth for your unique membership model.


Measuring success is all about knowing the numbers that matter. Master these four quadrants of key metrics – business, acquisition, behavioral, and community – to gain comprehensive visibility into your membership site’s performance and health. By diligently tracking KPIs, optimizing your efforts, and responding to the data, your community will thrive for the long haul.
