How to Build & Sell AI Agents: Ultimate Beginner’s Guide by Liam Ottley is a decoded YouTube video in the AI Tools for Business niche, with 3,892,724 recorded views. The public Decode shows the title, thumbnail and opening-hook observations from this specific video. Script and description details appear only when those dimensions were extracted. We do not have this video's click-through rate or watch-time analytics. The observations and templates on this page were written with AI from this video's own title, thumbnail and transcript; the templates are starting points to adapt, not a copy of this video. This title stacks two high-intent outcomes (build AND sell) into a single promise, which doubles the value proposition for viewers who want both skills. The 'Ultimate Beginner's Guide' qualifier removes friction by signaling accessibility, making a potentially intimidating topic feel achievable. The niche keyword 'AI Agents' is front-loaded and clear, so the algorithm and the viewer both know instantly what they're getting. The formulas below explain what was observed in this source video and how a channel could adapt the approach for the AI Tools for Business niche. The original YouTube video is linked above so you can inspect the title, thumbnail and footage yourself. These are patterns from one source, not a promise of views, subscribers or watch time.
