Include: (1) on-site SEO checks before publish, (2) email distribution to {{list_size}}-subscriber list, (3) repurposing into 8+ social formats with platform-specific cadence, (4) community/Slack/Discord drops, (5) outreach to people quoted/mentioned, (6) syndication options (Medium, Substack, dev.to), (7) paid amplification triggers, (8) measurement window and KPIs. Format as numbered checklist with owner and timing per step.
