Social Media Poster
Overview
Transform a single content brief into platform-optimized posts for LinkedIn, X, Instagram, and Facebook—automatically adapting format, tone, hashtags, and character limits, then scheduling and publishing on your behalf.
When to Use
- Publishing a product launch announcement across all channels simultaneously
- Scheduling a week of content from a single content calendar
- Repurposing a blog post or press release into social posts
- Running a coordinated multi-platform campaign
- Tracking engagement metrics across platforms after publishing
Instructions
- Accept inputs: content brief (topic, key messages, target audience, tone, media assets), target platforms, schedule (now/specific time/optimal time).
- Generate platform-specific variants:
- LinkedIn: professional tone, up to 3000 chars, 3-5 hashtags, no link in post.
- X/Twitter: concise, 280 chars, 2-3 hashtags, link at end.
- Instagram: visual caption, 2200 chars, 20-30 hashtags, call-to-action.
- Facebook: conversational, include link preview, 1-3 hashtags.
- Attach media assets if provided (resize/format per platform specs).
- If schedule=optimal, calculate best posting time per platform based on audience timezone and engagement data.
- Publish or schedule via each platform's API.
- After publishing, collect: impressions, likes, comments, shares, click-through rate.
- Return post URLs, publishing timestamps, and 24-hour engagement summary.
