SOSPosting connects Instagram, Facebook, TikTok, YouTube, Pinterest, LinkedIn, Threads, Bluesky, WordPress and Shopify, and fans one piece of content out to every network you tick — up to 7 for a photo, up to 5 for a video. It writes platform-native captions with AI, and optimises your Google Ads. These guides go deeper on how to do it well.
Guides

Publish one photo to up to 7 networks, or one video to up to 5 — with AI captions tuned for each.
- How to post to TikTok via API without the audit

- How to post to Instagram and TikTok at the same time
One vertical video becomes an Instagram Reel and a TikTok draft — with a native AI caption for each. The exact flow, plus the one manual tap TikTok still requires.

Queue Shorts up to 60 days ahead with an AI-written title, description and tags — uploaded and published hands-off at the minute you pick.
- Instagram auto-posting requirements: Business account setup
What Meta actually requires before any tool can publish to Instagram for you: a Business account, a linked Facebook Page and the right permissions — set up in about ten minutes.
- Cross-post Shopify products to social media automatically
Add a product once and it goes live as a Shopify listing, an Instagram Reel, a YouTube Short and more — with SEO copy and UTM-tagged links that tie posts to revenue.
