Google has updated the performance report within Google
Search Console to let you filter by “News” traffic in the search type filter.
Google said on Twitter, “Now you can analyze traffic coming from the News tab
on Google Search.”
Update: Now Google is sending email to those with news traffic of the
new News filter. It says "Google Search News tab data now in Search
Console Performance report. We've recently added new data to the
Performance report in Search Console: Google Search's News tab data.
This data shows clicks, impressions, and click-through rate for any
links seen in the "News" tab in Google Search results. To access this
data in the report, click the "Search type: Web" filter on the top of
the report, then select "News". For your convenience, you can also
