For me, the US statistics are most important for my business. In the slides, you can also find links to their Global report as well as other countries. Some of this information is fascinating! (If you like statistics, that is.)
Hootsuite is great, but I prefer Commun.it for Twitter management and Later.com for Instagram management. Later.com is free to use for 30 posts. That’s one Instagram post per day that you can schedule in advance. If you use my affiliate link, you will get an additional 10 monthly posts added, still for free! Commun.it is a paid service, but they have a 14-day free trial, so go check out their bells and whistles and see if it’s a fit for what you need! (This is also an affiliate link, but I personally use both of these services on a daily basis and love them!)
