If you need to know what subjects are being the most discussed within your mentions, you probably use our tagging feature. If you don't, you should read how to use tags for a more efficient monitoring!
Regarding the reporting, you can create custom charts with the tag segmentation to analyze the trends in your mentions and always know what the hot topics are.
From now on, it is also possible to choose the tags you want to display in a report using the Displayed tags option.
A quick exemple to illustrate how to use this feature:
Consider that you monitor a car show and have a tag for each car maker and one for mentions about electric cars. You can compare the share of voice of each car maker by choosing only the associated tags in the Displayed tags. If you want to compare that to the share of voice regarding the articles about electric cars, you can filter the data by selections only the mentions with the tag electric cars in the filters tab.
