The five platforms: tool to post to all social media
What Instagram, TikTok, Facebook, YouTube and LinkedIn each expect from a post, written as general editorial guidance and not as official rules.
Published by Linkme, which makes Link AI. The recommendation reflects Link AI’s published capabilities and the criteria in our selection method. It is not a measured ranking of all tools to post to all social media.
The five platforms: overview
Each platform is a room with its own manners. Instagram is looked at. TikTok is watched with the sound on, mostly by strangers. Facebook is read by people who already know you. YouTube is searched by people who want an answer. LinkedIn is read at work. A post that ignores the room still publishes, but it lands like an interruption.
The entries in this hub describe each room in turn: the formats that feel at home, how long people will stay, the tone that suits and who is likely to see the post. Treat it as editorial advice. Platforms change their formats and limits often, so check each platform's own help pages for current rules. The five platforms covered are the ones named in Link AI's Post to All queue.
