At Pugpig, our insights team works with customers to optimize their mobile apps, improving conversion, reducing churn, increasing ARPU and driving engagement. But while each of these metrics can tell a compelling story on its own, they don’t always reflect the full picture.
A publisher might see an increase in conversion, while a drop in overall engagement quietly impacts advertising revenue. Another might report rising push notification opt-ins, even as engagement declines, because the opt-in strategy was not aligned with the content being delivered. These outcomes are not isolated metric issues. They are symptoms of misalignment.
This challenge comes up frequently in our conversations with publishers. Teams want to understand how to measure success across their website, mobile apps and other digital properties, without improving one indicator in a way that undermines another. To help tackle that question, we asked Katie Ruane from Mather Economics to share her perspective. In this piece, we explore why subscription growth requires a systems-level approach and what that means for how publishers think about metrics and product decisions.
Mobile apps are often where the impact of misaligned KPIs becomes visible first. Apps combine conversion, onboarding, engagement, monetization and retention into a single environment, making cause and effect easier to observe over time.
Changes designed to improve app performance can deliver short-term gains while weakening longer-term outcomes. App-based conversion may increase following paywall or pricing changes, while newer subscribers fail to build regular reading habits. Push notifications can lift daily activity without strengthening retention if content relevance does not keep pace. Promotional offers may perform well in app stores while concealing churn risk further down the lifecycle.
Viewed in isolation, these results can appear positive. Viewed together, they highlight how decisions in one area affect outcomes elsewhere.
Subscription growth operates across multiple stages, and mobile apps are one of the few environments where those stages can be observed end-to-end. Apps link acquisition, onboarding, engagement, monetization and retention into a single usage context, which makes it easier to understand how decisions in one area influence outcomes later.
In an app, publishers can track whether users who convert go on to establish regular reading habits, how onboarding and early content choices affect repeat usage, and how notification strategies influence engagement over time. These signals often appear weeks or months before churn or renewal data, giving teams earlier feedback on whether a KPI change is strengthening or weakening long-term performance.
Rather than reviewing metrics as isolated snapshots, apps allow publishers to follow behavioral sequences and see how KPIs interact in practice.
As apps become more central to publishers’ subscription strategies, their data is increasingly used to connect metrics across the business. Engagement is no longer assessed on its own, but examined in relation to retention, revenue and lifetime value.
Publishers are linking app conversion events to downstream retention, evaluating notification strategies based on their impact on reading consistency, and using app cohorts to test the durability of growth. When app and website data are reviewed together, it becomes clearer whether improvements in one channel are reinforcing outcomes elsewhere, or creating hidden trade-offs that need to be addressed.
Publishers looking to align KPIs across their apps and websites can take a number of practical steps.
As discovery from search and social becomes less predictable, publishers are placing greater emphasis on owned platforms to support subscription growth. Mobile apps are increasingly where KPI alignment succeeds or fails. Publishers that place apps at the center of their measurement frameworks gain a clearer understanding of how performance connects across their business — and where adjustment is needed before trade-offs take hold.
