Amazon’s A10 algorithm strongly favors titles in the 150–200 character range, including spaces.
Once you go past 200 characters, your title gets truncated on mobile, which matters a lot since about 70% of traffic comes from phones. A solid 2026 title formula is simple: lead with your Brand (around 20%), follow with a Key Benefit (25%), layer in Core Keywords (40%), and finish with Size or Variant details (15%).
For example, “XYZ Premium Non-Stick Frying Pan 10-Inch Oven-Safe Induction Cookware Set of 2” clocks in at 83 characters and hits three primary keywords cleanly.
One pro tip: test your titles using Seller Central → Advertising → Search Term Report. Data consistently shows that titles longer than 80 characters can see up to a 15% drop in CTR. Pull exact-match keywords from your top three competitors and blend in high-impact phrases straight from your best reviews.
Leave the long-tail work to backend keywords, and always A/B test changes via Manage Inventory → Edit → Save & Finish—because mobile truncation quietly kills conversions.
