You may have noticed a change in your Google Analytics reports related to traffic coming from images.google.com. Google often runs small experiments to improve the value of our products for our users. One such experiment enabled a small percentage of Analytics customers to see traffic referred from images.google.com. Now that we have concluded the experiment, you will no longer be able to track referrer traffic from images.google.com in Analytics. However, you can see queries and click traffic from Google Images in the Performance report in Google Search Console, a tool that helps you understand your search traffic.
