Cross-posting guides
Cross-post to the platform you want
Each guide below covers one pair: where your post starts and where it lands. Socialync posts one upload to 9 platforms, and every guide shows how to write a separate caption for the platform at the other end.
A guide has five parts. You get the steps to follow in Socialync, formatting tips for the two platforms, common pitfalls, a pro tip and answers to the questions people ask about that pair. Where the platforms differ on caption length, video shape or hashtags, the guide says so.
This page groups the 26 guides by destination, so you can start from the platform you want to reach. The cross-posting index groups the same guides by source platform, which helps if you already know where your content lives.
The free plan includes 5 posts a month with no card, on 8 platforms. X posting is on paid plans. Paid plans start at $20 a month and include 5 connected accounts.
