Clicking the View link on the right side of the row will open an original review left by the reviewer.
Social Review
In the "Social Review Sources" setting, you can check and uncheck to show the data from the following sources: Facebook, Google, Indeed, Instagram, Just Dial, Mouthshut, Trip Advisor, Trust Pilot, Twitter and Yelp.
The "Social Review Types" setting allows you to set the type to Social reviews, Corporate Buzz, or both.
Review Text
The "Review Text" setting allows you to enter a keyword(s) and display only the reviews containing the word you want to focus on. Drilling down through a widget set up like that will also show reviews only with the selected word.
