What is it?

Indicates whether an event takes place in person, online, or as a hybrid of both. This property was added to schema.org during the COVID-19 pandemic and has become standard for any event that offers a virtual attendance option. It uses a fixed set of enumeration values from EventAttendanceModeEnumeration.

Why this matters for AEO

When a user asks "can I attend [event] remotely" or "is [conference] virtual this year," AI answer engines read eventAttendanceMode to give a direct yes or no. Without this field, the AI must parse the event description for phrases like "join online" or "virtual option available," which is unreliable and often missed.

What the specs say

Schema.org: EventAttendanceModeEnumeration. The eventAttendanceMode of an event indicates whether it occurs online, offline, or a mix. schema.org/eventAttendanceMode

Google: Not explicitly listed as a named property in Google's Event structured data documentation, but used in Google's examples for online and virtual events. Google Event docs

  "@type": "Event",
  "name": "Webflow Conf 2024",

CMS template pages

In Schema HQ

Configuration allows you to select the attendance mode from a dropdown and automatically pairs it with the correct location structure in the published JSON-LD.

FAQ

Do I need eventAttendanceMode if my event is in person?

It is not required, but adding OfflineEventAttendanceMode makes the format explicit for structured data consumers. For in-person-only events, omitting the field is acceptable since offline is the implied default.

How does eventAttendanceMode interact with location?

The attendance mode and location type should match. Use Place for offline, VirtualLocation for online, and an array of both for mixed. Mismatched values (online mode with a physical Place) create contradictory signals.

Was this property created for the pandemic?

Schema.org added eventAttendanceMode and VirtualLocation in response to the COVID-19 shift to virtual events. Both are now permanent parts of the vocabulary and widely adopted by ticketing platforms and event sites.
