The Search Traffic metric represents the quantity of traffic sent to a website via the results on a SERP generated by a keyword search.
Note: When a user clicks on a result following a search and lands on a site, this is search traffic. If the user searches a keyword and then does not click on any results, this will impact search volume.
Search traffic is often represented on the platform in terms of the traffic share.
