How it works

Ask Cecil something hard.

📎 cecil-ai-ad-copy-agent.skillLOADED ✓
Meta ads for our meal-prep app: CTR 0.6%, CPA $48 against a $30 target. The product converts fine from organic. Fix the copy?
CLAUDE · AS CECIL, AI AD COPY AGENT That CTR says hook failure, not product failure - 0.6% on Meta means the first line isn't stopping anyone. I write three angle variants per placement: pain-led, outcome-led and social-proof-led, each with correct character counts and a testing note on which to launch first. The metric to watch is CTR before CPA; get to 1.2% and your $48 CPA drops mechanically even at the same conversion rate. One reframe: don't 'fix the copy', test angles - you don't yet know which motivation drives your buyers. What's the main promise your organic traffic converts on?

What you're actually buying

Load Cecil into Claude and get a Senior Ad Copy Agent who writes platform-native paid advertising copy across Meta, Google Search, LinkedIn, TikTok, and YouTube - with three angle variants per platform, correct character counts, and testing notes on which variant to run first and what metric indicates a winner.

Most ad copy fails because it ignores funnel stage, treats platforms as interchangeable, and delivers phrasing variants instead of angle variants. Cecil fixes that. He asks targeted questions about the product, audience, funnel stage, and platforms before writing anything - then delivers direct response copy built to produce clicks and conversions, not win creative awards. Works with Claude, ChatGPT, or any AI chat model that accepts system prompts.

What you get

  • → Three angle variants per platform - each built on a genuinely different strategic premise (pain point, outcome, social proof, curiosity, urgency, offer-led) not just different phrasing of the same idea, so you are actually testing what works
  • → Correct character counts for every element - Meta primary text and headline, Google Search headlines and descriptions, LinkedIn introductory text, TikTok hook and script - all within platform specs so nothing gets truncated in the ad manager
  • → Testing notes per platform - which variant to run first and why, what the variable being tested is between variants, and what metric and threshold indicates a winning angle so the test is structured from day one
  • → Funnel-stage calibration - cold audience copy introduces and educates, warm audience copy builds desire, retargeting copy handles objections and closes - Cecil never mixes funnel stages in a single ad or delivers the wrong message to the wrong audience
  • → Platform-native copy - Meta, Google Search, LinkedIn, TikTok, and YouTube each in their own native register, because the casual scroll-stopper that works on TikTok will underperform on LinkedIn and vice versa
  • → Copy strategy notes - which angle is strongest for this product and why, what to test next after the first round, and any offer or landing page recommendations that would improve conversion regardless of how good the copy is
