How to write Amazon titles and bullets that fit the fields

A practical limit sheet for FBA sellers rewriting a listing. Updated September 2026.

Most weak Amazon titles are not short on keywords. They are long on panic. The backend still accepts a paragraph, mobile truncates it, and shoppers see a chopped clause that starts with “32oz Water Bottle Stainless Steel Vacuum…” and never reaches the fact that would have sold the unit.

This guide is about fitting the fields that actually display and index — not about stuffing every synonym into the title. If you want a worked example, the Fieldmark sample shows a stuffed before and a 61-character after. If you want the words written for you, that is an ASIN Pack.

Know the caps before you write

Amazon changes catalog rules by marketplace and product type. Treat these as working limits for a US retail listing, then re-check Seller Central for your category before you publish:

• Title: write to about 75 characters. Some backends still allow 200. Phones do not. A 75-character title also leaves room for Item Highlights to appear under it.
• Item Highlights: about 125 characters. One line. Indexed. Use it for facts the title did not have room for (lid type, base width, pack count).
• Bullets (Item Highlights / Product Benefits): five of them. Plan on 10–255 characters each, and keep the combined indexed window near 1,000 bytes. A 500-character essay in bullet four is often wasted.
• Backend search terms: 249 bytes, spaces not commas, no repeats of words already in the title, bullets, or description.

Byte counts matter for backend terms (accents and punctuation cost more than you think). Character counts matter for title and bullets. Count in a plain-text editor, not in a Google Doc with smart quotes.

Title: brand, product, one differentiator

A title that fits the field reads like a noun phrase, not a search query. Order that still works on a phone:

1. Brand (if you have one shoppers might look for)
2. Product type in ordinary English (“insulated stainless steel water bottle,” not “hydro flask type tumbler bottle”)
3. The one or two facts that separate the SKU (size, count, color, material)

Leave out: promotional language (“best,” “#1,” “sale”), shipping claims, years (“2026 new”), competitor names, and a second copy of the size. Color and size belong in variation themes when you have a parent; repeating them in every child title is fine when they are the only difference.

If you cannot say the differentiator in the leftover characters after brand + type, the differentiator does not belong in the title. Put it in Item Highlights or bullet one.

Item Highlights is not a second title

When Amazon shows this line, it is a caption, not a keyword dump. Name the facts a skimmer needs: leak-proof BPA-free lid, wide mouth, vacuum insulated, slim 2.9 in base. Commas are fine. Repeat the product type only if the title had to drop it — which it should not have.

Bullets: a lead-in, then proof

Five bullets. Each one should survive being read alone on a phone. A pattern that stays inside 255 characters without sounding like a catalog:

1. A short lead-in in plain caps or title case (the benefit in a few words)
2. A colon
3. One concrete proof: a measurement, a mechanism, a use, a limit

Proof is a 2.9-inch base, a silicone gasket, a wide mouth that takes a bottle brush. Proof is not “high quality,” “premium,” or “perfect for anyone.” If a sentence could sit on any SKU in the category, delete it.

Give each bullet a job so they do not paraphrase each other:

• Bullet 1 — the objection that causes returns (leaks, fit, sizing)
• Bullet 2 — the dimension or count people use to compare
• Bullet 3 — how the product does the job (insulation, fabric, motor)
• Bullet 4 — care, compatibility, or the unglamorous fact that prevents a 2-star review
• Bullet 5 — materials / who it is for, without turning into a gift-guide cliché

Keep the five together near 1,000 indexed bytes. If you are over, cut adjectives before you cut the measurement.

What not to do

• Do not comma-separate twenty end-use words (“gym, travel, hiking, camping, office, school…”). Pick the two that match how the product is actually used.
• Do not put a guarantee in the title. If you must mention a gasket or a lid, say what it does when closed — not “never leaks.”
• Do not hide the size. Shoppers compare 24 oz to 32 oz on the results page. If the title truncates before the size, you lose the comparison.
• Do not duplicate the title in bullet 1. The bullet should add a mechanism.
• Do not spend the indexed window on a holiday gift line. That copy dates and does not answer a complaint.

A one-sitting rewrite order

1. Write the 75-character title first. If it does not fit, the listing is not ready for bullets.
2. Pull three facts that did not fit. Those are Item Highlights candidates.
3. Read the 1–3 star public reviews. Each bullet should answer one of those themes without quoting a reviewer or inventing a testimonial.
4. Draft five bullets. Count characters. Cut until you are inside 255 each and ~1,000 together.
5. Only then write the description and backend terms. Backend terms get the leftovers (synonyms and use-cases that never appeared on the page).

For a full page walk-through — images, A+, attributes — use the listing optimization checklist.

When to stop editing

Stop when every field has a job and no field repeats another. A listing copywriter is not trying to win a density contest. The constraint is the point: 75 characters forces a choice, and the choice is what shoppers read.
