I love how quick and easy it is to create posts appropriate for multiple channels, especially Facebook and Twitter. It even allows you to create Instagram posts, and then emails it to you on schedule so you have the text and photo handy to post from your phone.
There are a ton of options for scheduling and presenting posts. Also, you can put posts into "Content Groups," however it makes sense for your business or pages, which is particularly powerful for analytics. You can see which types of content resonate best with the audience, where the engagement is, and learn what to ditch and where new opportunities lie.
It's hard to tag other pages in posts, and there's not a great preview to see what scheduled posts will look when they go live. So far the posts have looked fine, but I like to triple check everything before it goes out on a page.
Efficiency is the number one benefit. We've tried other tools and systems for managing social content and monitoring, and this is so far the best. Requires less steps and I can get it done faster, which is good when you are creating daily posts across 3 channels - or more. Highly recommend for social media managers working with high volumes of content. Also, there are great options for creating posting schedules, queues and evergreen posts - which means you can set it and forget it and keep your content in front of users.
