I originally signed up for mention to measure the social sentiment of one of the brands I managed. My first choice was Hootsuite but the form wasn't loading so I decided to try Mention. Best decision I ever made!
After signing up and setting up keywords to measure, alerts and dashboards, I forgot about Mention because it wasn't giving me info on past activity, I got an email from Account Executive at Mention and we scheduled a 15 minutes call to walk me through mention and answer my questions. The call helped me understand how to use mention, It also explained why the social sentiment dashboard wasn't showing much info. Mention doesn't show past data only data from when the account is set up.
I liked the email alerts on competitors social media mentions, I wanted to know who was mentioning my competitors and why, and if they were journalists, I could use Hunter and Clearbit to get their emails so I could send them a pitch.
I think the pros of Mention are: Good support from the Mention team, simple interface that is easy to use and resources such as webinars to make the most of the software, email alerts on competitors mention on social media, blogs, forums etc. And of course the simple social sentiment dashboard.
The brand I used Mention on was a small brand with little activity, and most social media interactions were in the past after we ran a campaign. Which didn't help much because Mention only showed data collected after setting up. I wish I could get sentiment from past activity so I can measure how my brand was viewed then and now.
