Social Post Generation agent
Social Post Generation is an agent in Mark (Optimizely Agent Platform). It takes a topic, URL, or key message. It generates platform-native social posts for LinkedIn, X, Instagram, Facebook, and TikTok.
- Challenge – Adapting one piece of long-form content for multiple social media platforms is repetitive and fragmented. Each network requires a specific tone, character count, and hashtag strategy. Maintaining high posting frequencies across LinkedIn, X, and Instagram becomes difficult without manual rework.
- Agent outcome – The agent automatically transforms existing assets or briefs into tailored social media posts. It generates platform-specific copy and recommends relevant hashtags. It also adjusts the messaging to match the audience expectations of each chosen channel.
- Value – The agent eliminates the manual rework required to adapt content for different platforms. It multiplies the reach of a single idea. It accelerates distribution workflows so you maintain a high-velocity social presence that stays on-brand and optimized for engagement without reformatting.

Use the agent
In Mark chat, enter @social_post_generation and provide details for the following parameters:
- Post Topic – Describe the milestone, launch, announcement, or theme. Add reference materials or links to relevant content.
- Target Audience – Specify the audience for these posts. For example, B2B marketing operations managers or Digital marketing leaders at mid-market companies.
- Channels – Comma-separated list of channels to generate posts for. For example, LinkedIn, Instagram, X, Facebook, TikTok.
- Primary CTA – Describe what you want readers to do. For example, Apply for cohort 2, Register for the webinar, or Read the case study. Include a link if you have one.
- (Optional) Brand Voice Notes – Two to three examples of your best-performing or most on-brand posts. The agent locks the voice and explores fresh angles instead of rephrasing what you have already written. Include tone guidance, words to avoid, or formatting preferences.
- (Optional) Research Brief – Use the research brief from the Social Post Research agent. The brief grounds the posts in current market signals, trending angles, and competitive context.
The agent delivers a canvas with platform-native posts organized by channel. Each post adapts tone, length, and format for its target platform.
