We have just launched a new Site Search Analytics Dashboard app that installs a robust site search-specific dashboard with the click of a button. 
The dashboard includes reports such as overall Click Through Rate, Clicks by Week, Searches by Week, Clicks & Searches by Vertical type, a Search Performance Overview and more! The out-of-the-box dashboard can even be customized further by adding more filters to any of the insights or adding more insights that you have already created in your account.
Install the app with the link above and dig into your search performance. We’ve got great feedback from Site Search customers already and would love to hear yours!
