Since launching the Google Assistant in 2016, we have seen users ask questions about everything from weather to recipes and news. In order to fulfill news queries with results people can count on, we collaborated on a new schema.org structured data specification called speakable for eligible publishers to mark up sections of a news article that are most relevant to be read aloud by the Google Assistant.

When people ask the Google Assistant -- "Hey Google, what's the latest news on NASA?", the Google Assistant responds with an excerpt from a news article and the name of the news organization. Then the Google Assistant asks if the user would like to hear another news article and also sends the relevant links to the user's mobile device.

As a news publisher, you can surface your content on the Google Assistant by implementing Speakable markup according to the developer documentation. This feature is now available for English language users in the US and we hope to launch in other languages and countries as soon as a sufficient number of publishers have implemented speakable. As this is a new feature, we are experimenting over time to refine the publisher and user experience.

UPDATE: After testing and further consideration, we have determined that the best place to measure query and click traffic from Google Images is in the Search Console Performance Report. Accordingly, we will continue to use https://www.google.com (or the appropriate ccTLD) as the referrer URL for all traffic from Google Images, and will not be providing a Google Images specific referrer URL (images.google.com).

Every day, hundreds of millions of people use Google Images to visually discover and explore content on the web. Whether it be finding ideas for your next baking project, or visual instructions on how to fix a flat tire, exploring image results can sometimes be much more helpful than exploring text.

Updating the referral source

For webmasters, it hasn't always been easy to understand the role Google Images plays in driving site traffic. To address this, we will roll out a new referrer URL specific to Google Images over the next few months. The referrer URL is part of the HTTP header, and indicates the last page the user was on and clicked to visit the destination webpage.
If you create software to track or analyze website traffic, we want you to be prepared for this change. Make sure that you are ingesting the new referer URL, and attribute the traffic to Google Images. The new referer URL is: https://images.google.com.
If you use Google Analytics to track site data, the new referral URL will be automatically ingested and traffic will be attributed to Google Images appropriately. Just to be clear, this change will not affect Search Console. Webmasters will continue to receive an aggregate list of top search queries that drive traffic to their site.

How this affects country-specific queries

The new referer URL has the same country code top level domain (ccTLD) as the URL used for searching on Google Images. In practice, this means that most visitors worldwide come from images.google.com. That's because last year, we made a change so that google.com became the default choice for searchers worldwide. However, some users may still choose to go directly to a country specific service, such as google.co.uk for the UK. For this use case, the referer uses that country TLD (for example, images.google.co.uk).
We hope this change will foster a healthy visual content ecosystem.
