My CTAs are weak so analyze: what specific CTA should I use? Map the CTA psychology: what action is most valuable (comment, share, save, follow)? Show me the CTA that algorithms reward most. Calculate: if I optimized CTA for algorithmic reward vs. audience action, which wins? Give me the CTA formula for my content type: this CTA drives this metric which triggers this algorithmic boost. Include: which CTAs actually work vs. which are generic, how to engineer CTAs for specific outcomes, and why "like and follow" might be the worst CTA.
