Measure sentiment and campaign effectiveness??

Donnieclark

Hello,
My topic is Pharmaceutical Video. Companies can track mentions of its products and rate mentions as positive, negative or neutral to measure sentiment. By tying mentions to PR and marketing campaigns, they can gauge the effectiveness of campaigns. They can then examine how marketing campaigns impact sales and ROI. Is this right information? I didn't get the right solution.
please help.

Any help will be appreciated.
Thank you.
