TEST YOUR AD CREATIVE FOR $0 BEFORE YOU SPEND A DOLLAR ON IT. Most people find out a concept is weak only after a platform has already charged them to show it. Run the hook, the copy, and the visual direction through Claude first. Have it grade against the specific patterns that actually burn ad budget, weak opening line, buried offer, no clear next step. Fix the obvious mistakes for free. Spend money on the version that already survived a real critique.(CyrilXBT)
