At my old organization, we used Hootsuite as a social media management tool in the marketing department, specifically as it relates to Twitter. Just using Twitter alone is fine, but Hootsuite allowed us to see mentions, interaction, etc. all in one view. No need to flip back between pages; it makes managing a social account easy.
In my current role, I use Hootsuite to manage my clients' social media channels similar to my previous role. When our team presented our clients with social platform management options, all of them opted for Hootsuite and have been extremely happy with the data, management, and ease of use that Hootsuite allows.
