Google is rolling out the activity cards feature it teased in a September blog post. Users can see search results they found in the past while searching for similar terms. Google gives users full control over how the activity card works, allowing them to pause it or choose not to see it if they don’t see it as a useful tool. The feature is currently rolling out today to English speaking US users of mobile web and the Google app users. Google will only show activity cards when website visited in past or previous search results would actually help.
