Bullet points — order, scannability, truncation.

The bullet block — Amazon calls it the "key product features" block — is the second-most-read element on the entire detail page after the title, beating the description, the A+ content, and most of the gallery. On desktop it sits directly under the title and to the right of the image carousel, above the fold for any shopper on a 13-inch laptop or larger. On mobile it collapses behind a "See more about this item" tap — meaning bullets one and two carry roughly 70–80% of the read-through, and bullets four and five are read by under 20% of shoppers. Treat the slot accordingly.

The hard rules Amazon enforces

• Five bullets max. Slots six through ten exist in the editor for legacy reasons but never render on the live PDP — wasted work.
• ~200 characters per bullet in most categories. A handful of categories (Beauty, Health) allow up to 500; most listings should stay tight at 150–250. Long bullets hurt scannability more than they help SEO.
• No HTML, no line breaks, no symbols beyond the hyphen. Pasted em-dashes, bullet glyphs (•), and emoji either get stripped or get the listing flagged at the next catalogue review.
• No promotional language. Words like "sale", "discount", "free shipping", "best", "#1", "guaranteed", and "100%" trigger automated flags. Some listings survive them for months; the suppression event when it lands is sudden and revenue-killing.
• No price, shipping, contact information, or competitor names. Amazon strips these and may suppress the listing if the pattern repeats.
• No ALL-CAPS sentences. The 2–4 word capitalised lead-in (see below) is the only sanctioned use of capitals.

The benefit-then-feature order

The canonical structure that consistently outperforms ad-hoc bullet writing:

1. Bullet 1 — the lead benefit. The single biggest outcome the shopper gets. Not the material, not the dimensions — the outcome. "SLEEPS COOLER ALL NIGHT — graphite-infused memory foam wicks body heat so you wake up dry."
2. Bullets 2–4 — the features that make the benefit credible. Materials, dimensions, capacity, certifications. The proof points behind the promise in bullet one.
3. Bullet 5 — the reassurance. Warranty, return policy, certification body, customer-service promise. The bullet that closes the loop for the cautious shopper at the bottom of the page.

This is the inverse of how engineering and product teams instinctively want to write bullets. The internal team wants to lead with the spec sheet; the shopper wants to lead with the result. The job of the listing owner is to translate features into outcomes — and to refuse to ship bullets that read like a packing slip.

Lead-ins that earn the read

Every bullet should open with a 2–4 word capitalised lead-in followed by a colon or em-dash, then the explanatory sentence. The lead-in is the one part of the bullet that shoppers consistently scan even when they don't read the rest. Bad lead-ins are interchangeable across competitors: "HIGH QUALITY", "PREMIUM MATERIAL", "GREAT GIFT", "100% SATISFACTION". Good lead-ins are specific and concrete: "SLEEPS COOLER", "FITS STANDARD KING", "OEKO-TEX CERTIFIED", "10-YEAR WARRANTY". Build the five lead-ins first, then write the supporting sentences underneath — it forces clarity into the bullet before you start polishing prose.

Mobile truncation — where shoppers actually look

On mobile, the bullet block renders behind a "See more about this item" link. Above the fold, Amazon shows only the first ~3 bullets and within each bullet only the first ~80 characters before truncation with an ellipsis. The full text appears only after a tap, and roughly 60% of mobile shoppers never tap. The practical implications:

• The first 80 characters of bullet 1 must carry the lead benefit completely. If your benefit needs 150 characters to land, restructure it.
• Bullets 4 and 5 effectively only exist for the indexing crawler and the small minority of shoppers who expand the block. Don't waste them, but don't put your strongest claim there.
• Test your bullet block on a 6-inch screen at typical scroll speed before you sign off. The desktop preview lies about how the bullets actually land.

Indexing — bullets carry real SEO weight

Bullets are indexed by Amazon's A9/A10 search engine alongside the title, the description, and the backend search terms. They are not as heavily weighted as the title, but they carry more weight than the description and significantly more than the backend search terms. The implication: secondary keywords that don't fit naturally in the title belong in the bullets, ideally embedded in the explanatory sentence so they read as prose, not as a keyword pile. The Listing course's Module 6 covers the indexing model in detail; for the bullet writer, the rule is "use real synonyms naturally, don't stuff".

Seller vs Vendor — same field, different update path

Sellers edit bullets directly in Seller Central → Manage Inventory → Edit, with changes typically live within minutes. Vendors edit bullets through Vendor Central's catalogue editor or, for larger updates, through a NIS (New Item Setup) form, with changes routing through Amazon's catalogue moderation queue and typically going live in 24–72 hours. Either side can be overridden by a "contributor" with higher trust — most commonly Amazon Retail itself on Vendor listings, or a Brand Registry owner on Seller listings. Lock down bullet contributors in Brand Registry → Manage Contributors if you want your bullets to stay your bullets.

Failure modes that recur

• All five bullets are features. The shopper never finds the outcome and bounces.
• Generic, interchangeable lead-ins. "HIGH QUALITY", "PREMIUM", "BEST CHOICE" — meaningless and used by every competitor in the category.
• Same benefit rephrased in three bullets. Wastes scarce slots and adds nothing for indexing.
• Bullet 1 starts with the brand name. Burns the highest-value slot on something the shopper already saw in the title.
• Promotional words. "Sale", "best", "#1", "guaranteed" — the listing survives until it doesn't, and the suppression is sudden.
• Hard ALL-CAPS sentences past the lead-in. Reads as shouting, hurts conversion, and trips formatting flags.

What to take into the next episode

Bullets carry the rational case. The next episode looks at the product description — the field most Brand-Registered sellers ignore because A+ Content overrides it, and the specific cases where it still appears, still indexes, and still earns its keep.
