I like the facts that Buffer gives you analytics on your posts to help you become a better poster. Buffer saves my posts so that I can go back and reposts posts that were successful. It also help me give analytics and data to my clients so that I can show them what I have done for them this month for social media if that is part of the packet they hired me for.
I dislike the fact that Buffer does not always follow the schedule that you set and sometimes misplaces links or changes them. Sometimes when I move a post from one day to another day, it automatically moves another post from another day into that vacant slot and that os not always something I want.
I would recommend Buffer to anyone who is serious about posting on Facebook and Twitter. If you are someone who posts with purpose and you plan posts out in advance, you need to add buffer to your workflow so that you can schedule posts out and create reusable social media content and get feedback with real time analytics on the things you already post.
I manage at least 12 social media accounts and using buffer is the only way I can manage that. It helps me schedule posts in advance and it helps me be organized.
