My engagement rate is killing reach so analyze: how do I manufacture comments? Map the comment-forcing techniques: controversial statements, fill-in-the-blank, wrong answers only, debate-starters. Show me the exact content structures that make NOT commenting harder than commenting. Calculate: if comment rate doubles, what's the algorithmic boost? Give me the comment-forcing playbook: these tactics guarantee comments, these fall flat. Include: how to create content that demands response, which comment types algorithm values most, and why lurker audiences kill accounts.
