The Foundation: The Ultimate Cheat Sheet Guide to All Major Social Networks

Update: You can now see the infographic in its entirety below.

In celebration of Social Media Day, we’re shipping our new, shareable, printable, hangable guide to all the major social networks: “The Foundation.”

No catch, no cost. The Foundation has the best times to post, ideal image size, ideal hashtags, post length, and more for Instagram, Facebook, Twitter, Pinterest, and LinkedIn. This data was sourced from almost half a million SumAll users and cross-referenced with other top social research.

We will be updating this document every quarter with SumAll subscribers getting it free of charge.

Thanks for reading. We hope you enjoy.
