Attributing revenue to a subscription calendar requires connecting your subscriber data and calendar engagement to downstream outcomes like purchases, renewals, or event attendance. There are several approaches depending on your setup.

Direct attribution via UTM parameters

Include UTM-tagged links in your calendar event descriptions. When subscribers click through from a calendar event to your website, those clicks are tracked in Google Analytics or your analytics platform with the UTM source and campaign you defined.

Example: a subscription calendar event for a product launch includes a link to your product page with ?utm_source=addevent_calendar&utm_campaign=fall_launch. Any purchases from that session are attributable to the calendar.

Subscriber list cross-reference

Export your AddEvent subscriber list (available on paid plans) and cross-reference it against your customer database or CRM. Compare the purchase rate, LTV, and engagement of calendar subscribers vs. non-subscribers. This gives you a cohort-level view of calendar marketing's impact.

Event attendance lift

For events with RSVP data, compare attendance rates between contacts who added the event to their calendar and those who did not. This measures the direct attendance value of the Add to Calendar step - Charity Navigator documented a 45% lift in donor conversions from a calendar-based intervention vs. a control group.

Subscription calendar in email attribution flow

If you promote your subscription calendar via email, include UTM parameters on the Follow Calendar button link. Subscribers who come via email are traceable to the email campaign in your analytics.

AddEvent's built-in analytics

AddEvent's analytics dashboard (Small Business plans and above) shows Add to Calendar clicks, calendar app breakdown, and subscriber growth over time. While it does not connect directly to revenue, these metrics serve as leading indicators - high Add to Calendar conversion correlates with higher attendance, which correlates with downstream revenue.
