CoSchedule is a WordPress plugin that is an editorial calendar and a social media scheduling tool. It offers great features that are just what you need. Not only can you create a drag-and-drop editorial calendar in order to plan your posts in advance, but you can also pre-schedule your social media promotions for each of those blog posts. CoSchedule supports Twitter, Facebook, LinkedIn, Google+, and Tumblr. It also offers some neat analytics to see how many times your posts have been shared. I highly recommend this tool!
Lastly, Latergramme enables you to schedule your Instagram posts. You can schedule all of your posts ahead of time and receive a push notification when your Instagram image is ready to be published. All you have to do is swipe to open it and then publish your pre-made Instagram photo onto your account.
Ahalogy is exclusively for scheduling Pinterest posts. This tools has received a lot of positive feedback from its customers. In order to join, you’ll have to request an invite. Once approved, you’ll be joined into their network of pinners, and will have the option to both schedule your own pins and to pin content from their “network of high-end content creators.”
Buffer + Hootsuite
Buffer and Hootsuite are excellent programs for scheduling Facebook and Twitter promotions, though they also offer scheduling to Google+ and LinkedIn. I grouped them here together because they offer very similar services, and you likely would only need to use one or the other. The biggest difference I’ve found is that Buffer now has the option to schedule pins to Pinterest, too. I currently use Hootsuite to schedule my social media and it makes the process very easy.
Pricing: You can use both of these programs for free, but for more freedom, they offer paid plans as well, starting at about $10. (Source: melysagrifin.com).
