Your 75-char title and 125-char Item Highlights carry 200 characters in Amazon's primary index. Your A+ image alt-text is a separate surface — confirmed crawled by Google, widely believed indexed by Amazon. This generates net-new overlay headlines and alt-text from the validated demand your title had no room for. Generation only — it never critiques your existing A+.
Enter an ASIN. We compose the title + Item Highlights first (they set the repetition rules), then generate the A+ plan from what's left over. Already have a title? Paste it to skip that step.
