‘mark up your listings’ updates.

Much needed update to the Galleries/Lists page

Now titled “Carousels”, it has a lot more detail and better explanation of the requirements for getting the Carousel, and what you will actually get for implementing it (the old page was pretty vague)

The two best points are

  • All items in the list must be of the same type, for example: Article or Recipe.
  • List format is currently supported for the following content types. This list is growing, so feel free to create a list for other types as they become supported: Recipe, Film, Course, Article, Recipe.

Update They have removed this text from the page and upon testing, can confirm this bug seems to be fixed now.

Also it gives notices about the bug in the structured data testing tool:

A note about the samples: The url property values in the embedded code samples are reported as errors by the Structured Data Testing Tool. This is only because the tool expects the url value to match the page hosting the data–in this case, the Structured Data Testing Tool itself. Therefore you can ignore this error in the samples.

Would have just been nicer if they fixed the bug that has been present for years.. but oh well.

They’ve also fixed the missing information warnings that were present in the examples, and separated the two ways to use the ItemList: summary page with single detail pages, or full page listing.

Updates to structured data guides – search gallery and events.

Today (11th of May) Google updated their search gallery page and the event page.

The search gallery now has links and thumbnails for all the features, adding site enhancements – (Breadcrumbs , Corporate Contacts, Galleries and Lists, Logos, Sitelinks Searchbox, Site Name, and Social Profile Links)

It has also added all the content types (including the new Fact Check type) to the table in alphabetical order, while now linking to the guide page rather than a link to example markup on the structured data testing tool.


The events page is completely reworked.

  • Much shorter guide, a lot clearer, now only has 1 example of JSON-ld markup, rather than 13 examples on the old page.
  • Removal of delegation section, not sure if this is now not supported, or just not publicised.
  • Splitting required and recommended in to separate tables.

Most interesting is that they explicitly say “Adding recommended fields might be factored into ranking in the enhanced Search results.” It seems that mark up can effect rankings, at least among rich results.

It seems that Google are working on making it simpler for people to understand the guidelines. I imagine over the next few weeks the other data types will be getting the same makeover.
