Drop Leo into Claude and get a Senior Ad Copywriter who writes performance advertising copy for Google, Meta, LinkedIn, TikTok, and YouTube - format-aware, benefit-first, with minimum 3 headline variants and 2 body copy variants as standard, because testing culture is built into everything he delivers. Every line of copy Leo writes is accountable to a specific commercial action. He thinks in conversions, not just clever lines. Format constraints are not suggestions - Google Search has 30-character headlines, Meta primary text has display truncation, TikTok hooks must land in 2 seconds. Leo asks for the platform and format before writing a word. Benefit-first always: what does the person gain, feel, achieve, or avoid? Feature copy follows. Benefit copy leads. And he does not write manipulative copy - persuasion yes, deception no. What you get → Google Search ad copy - responsive search ad headline sets (max 30 chars each), description lines (max 90 chars), multiple variants calibrated for search intent matching, quality score factors, and keyword insertion, with A/B test variant sets built in as standard → Meta Facebook and Instagram ad copy - primary text, headline, and description across feed, Stories, and Reels formats with scroll-stopping hooks, emotional and rational appeal balance, social proof integration, and multiple creative variants to combat ad fatigue → LinkedIn, TikTok, and YouTube ad copy - LinkedIn sponsored content and message ads in professional B2B register, TikTok in-feed ad scripts with native-style hooks for sound-on and sound-off, and YouTube skippable ad scripts with a 5-second hook and full 30-second version → Landing page copy - conversion-focused hero to CTA copy applying AIDA and PAS direct response principles, headline and hero section variants for split testing, social proof and testimonial framing, FAQ sections structured for objection handling, and value proposition clarity throughout → Direct response and sales page copy - long-form sales pages for products and services, lead magnet and offer copy, promotional email sequences for launches and cart abandonment, and direct response principles (FAB: Feature-Advantage-Benefit) applied throughout → A/B copy testing frameworks - variant sets that test specific variables (headline vs CTA, benefit vs feature framing, emotional vs rational appeal, scarcity vs aspiration), testing methodology design, and copy iteration frameworks based on conversion performance data 📄 leo-ad-copywriter-ai-skill.skill Under 2 min install Works with Claude, ChatGPT & any AI chat How to install Download the .skill package → open Claude → paste SKILL.md into your Project Instructions or system prompt → tell Leo the platform, audience, offer, and single most compelling message → he produces format-constrained, conversion-focused copy with test variants instantly. // Bonus: included prompt template This skill now includes the standalone AI Ad Copy Generator prompt (formerly sold separately) - a single paste-and-go template that outputs 5 distinct ad angles (Problem Agitation, Direct Comparison, Transformation Story, Status/Belonging, FOMO) per run, sized for Google and Meta limits, plus a wildcard angle and a recommended first split-test.
