1. Metrics and Calculations

Description
Average digital-only subscription lifetime in months (modelled)Measures the estimated length of an average digital-only subscription relationship in months. We model this value using monthly churn rates.
Average revenue per subscriber (ARPU)Measures the value of an average subscriber. We calculate a ratio of the total digital-only subscription revenue per the total number of digital-only subscribers in a month. To compare ARPU across brands and countries, we adjust values in local currencies for the purchasing power of the local currency vs. U.S. dollar. We use the World Bank's purchasing power parities for 2023. More: worldbank.org
Casual usersMeasures the size of the segment of online users who did between 2 and 9 sessions in a month. We calculate this number based on the total number of online users in a month, and segments of users who did 1 and at least 10 sessions in a month.
Check-out flow efficiency rateMeasures the effectiveness of the subscription flow. We calculate a ratio of check-out finishes to check-out flow starts in a month.
Check-out flow finishesMeasures the effectiveness of the subscription flow. We collect the number of users who viewed the last page in the check-out flow (e.g., payment success page) in a month.
Check-out flow startsMeasures the effectiveness of the subscription flow. We collect the number of users who viewed the first page in the check-out flow (e.g., landing page with offers) in a month.
Check-out start rateMeasures the attractiveness of the subscription offer. We calculate a ratio of check out starts to paywall stops in a month.
Clicks per opt-ins rateMeasures the performance of the e-mail newsletter database. We calculate a ratio of all e-mail newsletter clicks to the total number of users registered to newsletters in a month.
Clicks to opens rateMeasures the effectiveness of the newsletter program. We calculate a ratio of all e-mail newsletter clicks to all e-mail newsletter opens in a month.
Content formulaInforms what best describes a content formula of a brand: quality news (e.g, historic broadsheet), popular news (e.g., historic tabloid), niche (e.g., sports, business), non-news (e.g., lifestyle, hobbies). We ask brands to declare this information.
Depth of sessionsMeasures average user's engagement with the site's content. We calculate a ratio of number of pageviews per session in a month.
Digital subscription churn rateMeasures the effectiveness of the subscription program. We calculate a ratio of online subscriptions that were stopped in a given month to online subscriptions at the end of a previous month.
Digital subscription penetration rateMeasures the effectiveness of the subscription program. We calculate a ratio of online subscriptions to online users in a month.
Digital-only subscription acquisition rateMeasures the effectiveness of the publisher's subscription acquisition efforts. We calculate a ratio of digital-only paid subscriptions that were started in a given month to digital-only paid subscriptions at the end of that month.
Digital-only subscription revenueMeasures digital reader revenue. We collect the total revenue collected from all digital-only subscriptions in a month in U.S. dollars at the exchange rate for the last day in each month.
Digital-only subscription startsMeasures demand for subscriptions. We collect the number of digital-only subscriptions for which contracts were started during a month.
Digital-only subscription stopsMeasures demand for subscriptions. We collect the number of digital-only subscriptions for which contracts were cancelled their contract during a month.
Dwell time of sessionsMeasures average user's engagement with the site's content. We collect an average session duration in minutes and seconds.

Heavy usersMeasures the size of the segment of online users who did 10 and more sessions in a month.
In-market householdsMeasures the size of the total addressable market of a site. We collect the number of households in the area of focus of the publisher, e.g., a distribution area for a printed product or news coverage area for an online site.
Known usersMeasures the size of the audience that is known to a site. We collect the number of users who are registered, subscribed or for any other reason gave their identifier, such as e-mail, to the publisher.
Known users with digital-only subscriptionMeasures the effectiveness of the online reader engagement. We calculate the proportion of known users with digital-only subscription, by dividing the number of users who are registered subscribed or for any other reason gave their identifier, such as e-mail, to the publisher by the number of digital-only subscriptions.
Lifetime valueMeasures the estimated revenue that a digital-only subscription will generate for a company over the entire period of their digital subscription. We model this value using the average survival (retention) rate and a monthly average revenue per digital-only subscription, and present it for the first 12 and 36 months.
Market penetration rate (all paid subscriptions)Measures the reach of the subscription program. We calculate the proportion of households in the market that signed up for any paid subscription, by dividing the number of paid subscriptions (digital, print, others) by the number of in-market households.
Market penetration rate (digital-only subscriptions)Measures the reach of the digital subscription program. We calculate the proportion of households in the market that signed up for a digital-only subscription, by dividing the number of digital-only subscriptions by the number of in-market households.
Market penetration rate (known users)Measures the reach of the audience that is known to the site. We calculate the proportion of households in the market that are registered, subscribed or for any other reason gave their identifier, such as e-mail to the publisher, by dividing the number of known users by the number of in-market households. This rate may exceed 100%, as users might use multiple identifiers, across multiple websites, and publishers' databases might not be deduplicated.
Market penetration rate (online users)Measures the reach of the site. We calculate the proportion of households in the market that accessed the website in a month, by dividing the number of online users by the number of in-market households. This rate may exceed 100%, as households may be larger than one person, users might access with multiple devices and browsers, and part of the audience may be out of market.
Newsletter click-through rateMeasures engagement with e-mail newsletters. We calculate a ratio of newsletter clicks to newsletter sends.
Newsletter click-throughsMeasures the effectiveness of the newsletter program. We collect the number of unique newsletter click-throughs or sessions with newsletters being the visits' source.
Newsletter e-mail databaseMeasures e-mail newsletter capture effectiveness. We collect the total number of users registered to newsletters in a given month.
Newsletter open rateMeasures engagement with e-mail newsletters. We calculate a ratio of newsletter opens to newsletter sends.
Newsletter opensMeasures the performance of the newsletter program. We collect the number of unique newsletter opens in a month.
Newsletter opt-in rateMeasures e-mail newsletter capture effectiveness. We calculate a ratio of users registered to newsletters to the total number of online users.
Newsletter sendsMeasures the performance of the newsletter program. We collect the number of unique newsletter e-mails sent to all recipients in a month.
Online UsersMeasures size of the audience. We collect the number of all users active in a month.
Opens per opt-ins rateMeasures the performance of the e-mail newsletter database. We calculate a ratio of all e-mail newsletter opens to the total number of users registered to newsletters in a month.
Other paid subscriptions with digital accessMeasures the progress of digital transformation. We calculate the proportion of non-digital only paid subscriptions (e.g., print, others) with activated access to subscriber-only online content and features, by dividing the number of other paid subscriptions by the number of other paid subscriptions with activated access to subscriber-only online content and features.
PageviewsMeasures demand for online news. We collect the number of pageviews generated by all users in a month.
Paid stop conversion rateMeasures the effectiveness of the paywall. We calculate a ratio of check-out finishes to paywall stops in a month.
Paid subscriptionsMeasures the size of the total paid subscription base. We collect the number of paid subscriptions to the online editions, print editions, e-replica of the print editions, etc. on the last day of a month.
Paid subscriptions that are digital-onlyMeasures the progress of digital transformation. We calculate the proportion of total paid subscriptions that are digital-only, by dividing the number of digital-only subscriptions by the total number of paid subscriptions (digital, print, others). This rate might reach 100% for publishers which don't sell print or other subscriptions.
Paywall stop rateMeasures the effectiveness of the paywall. We calculate a ratio of users who hit a wall and were exposed to subscription offers to online users in a month.
Paywall stopsMeasures the effectiveness of the paywall. We collect the number of users in a month that were exposed to an offer to subscribe by hitting a barrier (modal, interstitial, inline wall).
Paywall typeInforms what type of a digital subscription access model generated most of conversions in the past quarter: no paywall/membership, freemium, metered, hard or hybrid. We ask brands to declare this information.
Ratio of new subscription starts per 1 million usersMeasures the effectiveness of the publisher's engagement and subscription acquisition efforts. We calculate a ratio of the number of digital-only paid subscription starts to the number of online users in a month.
SessionsMeasures demand for online news. We collect the number of sessions generated by all users in a month.
Survival (retention) rateRefers to the percentage of digital-only subscribers who remain subscribed over a specified period of time. We model this rate for the first 36 months using the average monthly churn rates, and present an average for the entire digital-only subscription base.
User engagementMeasures average user's engagement with the site's content. We calculate a ratio of number of sessions per user in a month.
Website penetration rate (digital-only subscriptions)Measures the reach of the digital subscription program relative to the online audience. We calculate the proportion of online users that signed up for a digital-only subscription, by dividing the number of digital-only subscriptions by the number of online users. This rate fluctuates, as the number of online users changes with a news cycle.
Website penetration rate (known users)Measures the reach of the registration program relative to the online audience. We calculate the proportion of online users that are registered, subscribed or for any other reason gave their identifier, such as e-mail to the publisher, by dividing the number of known users by the number of online users. This rate fluctuates, as the number of online users changes with a news cycle. This rate may exceed 100%, as users might use multiple identifiers, across multiple websites, and publishers' databases might not be deduplicated.
