What is a KPI? What is the right KPI?

A KPI is a Key Performance Indicator. They measure if your efforts are earning you the result you want and need. KPI metrics are essential to our job as marketers, but remember—they’re not the only measure of success. 

The real results of Catholic marketing sometimes don’t show up in the numbers we’re told are most important.

Likes don’t tell the whole story when your goal is to bring people closer to God. Your website may have a lot of viewers, but their time on page is two seconds. 

Understanding which analytics really prove impact can be the difference between a successful campaign and a wasted one. 

If you’re running marketing for a diocese or parish, Catholic school or nonprofit, here’s what you should care about when it comes to marketing analytics:

1. Website Traffic

KPI metrics to watch:

• Time on Page: Are they actually getting value out of the page, or do they bounce in two seconds? Low time on page may mean the page needs to be easier to navigate or the value more upfront for new visitors. 
• Sessions Based on Source/Medium: How many visitors found your site from social media, organic search, email, etc.? This knowledge helps you learn how to tweak your website experience to fit the needs of the audience. 
• Top Pages: Which pages does your audience visit most? Let those topics inform more social posts or emails, optimize those pages for search, and ensure a smooth user experience to boost engagement rates.

Why it matters: If you’re seeing more traffic from a certain platform (say, Facebook or Instagram), it means you’re reaching your audience where they’re already hanging out. If your traffic is mostly coming from organic search, it means your SEO is working. 

Either way, this is an insight into where to double down or adjust your efforts.

But don’t be surprised if a spike in traffic doesn’t immediately result in more donations or sign-ups. People might visit your site and then take action later, offline. It might take time. That’s okay! Results aren’t always immediate.

2. Social Media Engagement

KPI metrics to watch:

• Shares: People like the content and think it’s so valuable that they want their friends or family to experience it, too. 
• Quality Comments: People share their experiences, ask thoughtful questions, or express how much the content meant to them. These engagements are probably the best metric a social media manager can see because they reveal the hidden metrics of impact and transformation. 
• Click-Through Rate (CTR): Are people actually swiping through your carousels or clicking your links? This can enlighten you as to what engages and what doesn’t.

Why it matters: Engagement is a direct reflection of how much your audience cares about your message. If you’re not earning engagement, it might be time to re-evaluate your content or strategy. If you see high engagement, you’re on the right track, and it’s time to build on that momentum.

Keep in mind the hidden metrics. Some people might engage deeply with your content—screenshots, prayers said because of your post, showing a post to a friend or relative in person, hearts opening, feeling seen, etc.—but never like, comment, or share it. 

They could show up at church, volunteer, or give a donation without saying a word online. Offline results matter more. 

But you have to start somewhere.

3. Conversions

KPI metrics to watch:

• Conversion Rate: The percentage of people who complete the action you want (e.g., donations, event registrations). 
• Form Submissions: How many people fill out your contact forms, volunteer applications, or prayer request forms? 
• E-Commerce Transactions (if applicable): For Catholic stores or nonprofits, how many products are sold or donations made?

This isn’t a blog bashing TikTok Shop or affiliate marketing. Both are smart strategies, and people do discover genuinely helpful things that way. But in this economy, where every dollar counts, we have to pause and ask better questions before buying into everything we see.

Why it matters: All of these are great metrics to show that your content is inspiring in-person impact.

A high conversion rate means your audience isn’t just passively consuming content—they’re doing something about it. That’s the ultimate goal: to inspire people to engage with your mission, whether that’s through giving, volunteering, or attending events. If your conversion rate is low, take a look at your calls to action, your landing pages, or your follow-up processes.

But once again—don’t be discouraged if conversions don’t show up immediately in the numbers. Some people might be motivated to take action offline after seeing your message online. Maybe they’ll go to confession, show up to Mass, or even attend a parish event.

These are big wins.

4. Email Metrics

Email marketing is one of the most powerful tools for organizations to connect with their audience. But it only works if you’re paying attention to the right metrics. The key to success is crafting emails that get opened, read, and acted upon.

KPI metrics to watch:

• Open Rate: This tells you how compelling your subject line was and how important you are in the inbox. Without an open, nothing else happens!
• Click Rate: How many people clicked the links inside your email (e.g., donation, article, video, event sign-up)? Your email might be nice to skim, but is it worth more?
• Bounce Rate: How many emails didn’t get delivered? A high bounce rate means you need to clean up your email list.
• Unsubscribes: This is a dreaded metric. High unsubscribe rates could mean you are talking to the wrong people, emailing too much, or delivering little value. 
• Forwards: If your audience is sharing emails with others, you have made a difference. Nice work!

Why it matters: Email gives you direct access to your audience’s inbox. If your open and click rates are low, it’s time to revisit your subject lines, messaging, or frequency. If they’re high, you’re nailing it, and your audience is active.

But, like the other KPI metrics, don’t get hung up on numbers. Maybe the person who didn’t click on your donation link today will come to Mass and donate in person. Offline conversions matter just as much as online ones.

Conclusion

When you’re analyzing a campaign’s progress or reporting on its success, remember to dig deeper into the analytics that actually prove the impact you want to make beyond likes and web page views. 

But keep in mind, too, that not all impact can be measured online. If anyone sends you a kind message or tells you a story of something they did because of your marketing, hold it close. Frame it. Hang onto it in the moments when you feel like nothing is breaking through. 

Catholic marketing isn’t just about what happens online. It’s our job to start the conversation. God will turn it into something more powerful.
