Both Search Experience and Research Cloud can display the keywords that have lost the most rankings over a given period of time (loser keywords) and how that negatively affects the traffic. These insights can be very helpful. For example, if your traffic is severely degrading, you might want to search for a trigger for loser keywords.
Workflow example: My SEO Visibility is losing value - why is it so?
1. Open Google updates in the SEO Visibility chart to see if the drop is possibly caused by one of them. The following diagram does not indicate that the Google update is directly related to the dropout.
2. The winners and losers section should analyze which keywords are responsible for changing the visibility. In order to do do this, select the loser keywords and the date when it happened. Now compare the loss of the loser keywords or URLs with the loss of a domain to determine a possible connection.
3. The same analysis can be done for winner and loser keywords in the Search Experience to get more information.
