The Word Cloud widget displays words from the text of the reviews, sized by frequency.
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.
While hoovering over a word will show you the amount of the reviews, clicking on one will open a pop-up, displaying the review details.
Remember to check a different help article detailing other settings of this widget.
