When you use structured data to mark up items for lists, you make your content eligible for inclusion in a sequence-based UI in Search, allowing users to easily swipe or scroll through a list of items right from within Search results, which leads them more quickly to the right content on your site. This document describes how to mark up two types of lists:
- Host-specific lists—displays recipe cards from a single site within a specific category. This markup uses a combination of ItemList markup and individual data type markup to enable a carousel of lists to appear in Search.
- Events—enables a carousel of events from authoritative event websites.
Mark up host-specific lists
To make your content eligible for a host-specific list, you use two types of markup:
- List Page markup—this markup specifies the list, its items, and their order.
- Item-specific markup—this markup notes the properties for the
data type you want to have in the list, such as
Provide markup for the
ItemList data type by using these required properties.
|itemListElement (Required)||ListItem||Annotation for a single item page.|
|ListItem.position (Required)||Integer||Ordinal position of the item page in the list.|
|ListItem.url (Required)||URL||The canonical URL of the item page. Every item should have a unique URL.|
Data type markup
To enable host-specific lists, you first expose the data type properties you want to make available for presentation in your list, such as an image, a description, and other relevant details. The recipe data type has a required set of properties that must be marked up in order to qualify that content for inclusion in the recipe list. We also encourage you to mark up all available properties for your items for a better experience for your users See the data type reference for Recipes for specifics.
How to mark up host-specific lists
You can mark up your lists in two ways:
- Separately—When a recipe has its own page, use data type markup on individual item pages. Use list page markup on the summary page that links out to the items. If you use this method, the visible content on the summary page must contain the same content that you specify in the markup, such as your site’s listing of user’s favorite dinner recipes. See Structured data guidelines in Introduction to Structured Data for specifics.
- Combined—When multiple recipes are on a single page, use list page markup that both
itemizes the data types and exposes their properties in the
In this case, be sure to include a unique URL for each item, which in this case might include an anchor tag.

Mark up event listings
Millions of users ask Google questions about upcoming events every day —but to answer those questions well, Google needs structured data directly from the most authoritative websites for each event. This documentation describes how event organizers, performers, venues, ticketers, and hosting platforms can participate directly in event Search features.
As with markup for host-specific recipe lists, you will need to mark up the
event information on your site using the
Event data type and provide
the relevant properties for your events. You do not need
to provide list markup in order for your events to appear in an event carousel
in Search results.
For event-specific examples, guidelines, and data type properties, see the data type reference for Events.
Use one of the following methods to provide structured data for Events:
- Embed event data type markup directly to the event listings.
- Use a markup-compatible events plugin or widget.
This is an easy, reliable option if your events listing is powered by one of the supported platforms described in the Event data type reference under Supported markup widgets and plugins. If you don’t see your widget or plugin on the list, ask your content management plugin provider to support event markup.
- Rely on your venue's primary ticketer(s) to add structured data markup to their websites.
Google will supplement the venue site's event listings with events found on ticketer websites.
Troubleshooting events in Knowledge Graph cards
Knowledge Graph card display is governed by a complex algorithm, so if you don’t see your artist or your artist’s events in the Knowledge Graph card, try these steps:
- Make sure that the artist is in both Wikipedia and MusicBrainz, and that the artist's official home page is recorded properly on both those sites.
- For events missing from a Knowledge Graph card, check that the events are shown correctly with no errors in the Structured Data Testing Tool. If all fields look correct, report the missing events using the Feedback link under the Knowledge Graph card in Google search. Please report it as general feedback and be sure to use the term events in your description of the problem.
