حدود أحرف قوائم أمازون: فخ البايت الذي لا يحذرك منه أحد
حقل كلمات البحث الخلفية لا يحسب الأحرف بل بايتات UTF-8 — وقد تتجاوز الحد دون أن تعلم.
The Limits That Matter
| Field | Typical limit | Counted in |
|---|---|---|
| Title | 200 characters (varies by category) | Characters |
| Bullet points | Commonly ~250 characters each (varies) | Characters |
| Backend search terms | 250 | UTF-8 bytes |
Two things trip sellers up. First, title limits are per category — check your category style guide rather than assuming 200. Second, and far less known: the backend search-terms limit is measured in bytes, not characters.
Why Bytes ≠ Characters
In UTF-8 encoding, plain ASCII letters (a–z, 0–9) take 1 byte each. Accented and non-Latin characters take 2 or more: ü, ş, ğ, é, ñ, ö are all 2 bytes; Arabic, Cyrillic and CJK characters take 2–4.
A Turkish or German keyword list that a character counter says is 'exactly 250' can be 270+ bytes — and everything past the byte limit is at risk of being ignored by Amazon's indexer. You lose your last keywords without any warning.
Practical Rules for Search Terms
- Count bytes, not characters, before pasting into the backend field
- Don't repeat words that already appear in your title or bullets — the field is for new terms
- Skip commas if you like — spaces separate terms and commas just spend bytes
- No competitor brand names, no ASINs, no 'best/cheapest' claims — policy violations can suppress the listing
- Prioritize your highest-value missing keywords first, so if anything gets cut at the limit, it's the least important
Titles: Fit the Limit Without Stuffing
A title that hits the character ceiling isn't automatically a good title. Lead with what buyers scan for: brand, product type, the one or two attributes that drive the purchase (size, count, material, compatibility). Keyword coverage belongs across the whole listing — title, bullets, and backend terms working together, without duplication.
