On Amazon the listing is the ad. Titles, bullets, and the Sponsored Brands headline each have caps that affect both ranking and conversion — here they are.
Amazon advertising leans on the listing itself: the title, five bullet points, and the product description carry the message, while Sponsored Brands adds a short custom headline. Titles can run to 200 characters but mobile shows far fewer, so the first words decide visibility in search.
| Field | Limit | Notes |
|---|---|---|
| Product title | ~200 characters | Mobile shows ~80 — front-load brand + key terms. |
| Bullet point (each) | ~500 characters | Five bullets; lead each with the benefit. |
| Sponsored Brands headline | 50 characters | Custom headline above the brand's ad. |
| Product description / A+ | ~2,000 characters | Plain description; A+ content replaces it visually. |
Most categories allow up to 200 characters, but mobile search shows roughly the first 80. Lead with brand and the highest-intent keywords.
Five bullet points, each up to about 500 characters. Lead every bullet with the customer benefit, not just the spec.
