Most product titles fail one of two jobs: they either keyword-stuff and read like spam, or they read nicely and never surface in search. A title that works does three things at once — it carries the primary keyword, names the buyer outcome, and respects the platform’s character cap and mobile-crop point. The 12 prompts below pull both levers together. Paste them into ChatGPT (GPT-5.5), Claude (Sonnet 4.6), or Gemini 3.1 Pro; all three handle this well, and the structured output rules in each prompt matter more than the model. Once a title wins, move on to product description prompts.
TL;DR
- Front-load the primary keyword. Every marketplace crops on mobile, usually inside the first 40-80 characters.
- Match the cap to the platform: Amazon 200, Etsy 140 (but aim under 70 in 2026), eBay 80, TikTok Shop 25-200, Shopify on-page 50-65.
- Name the buyer outcome, not just the spec — especially on a DTC store where shoppers don’t know your feature jargon.
- A/B test ONE variable per pair so a winner actually teaches you something.
- Use the character-cap table below as a checklist before you publish any title an AI writes.
Platform title caps and mobile crop points (June 2026)
The single most common AI-title mistake is generating a title that’s perfect for one platform and broken on the next. These are the current limits — paste the relevant row into your prompt so the model writes to the right cap the first time.
| Platform | Hard cap | Recommended length | Mobile crops at | Notes |
|---|---|---|---|---|
| Amazon | 200 chars (apparel 125; baby/pet 80) | 80-100 chars | ~80 chars | Banned: all-caps, promo words (“BEST”, “#1”); auto-corrected after ~14 days |
| Etsy | 140 chars | under 70 chars (2026 soft cap) | 40-50 chars | Titles over 70 chars now face lower mobile visibility; pipe-separated clusters |
| eBay | 80 chars | 60-70 chars | 50-55 chars | Specs/model up front; readability now affects ranking |
| TikTok Shop | 25-200 chars | 40-80 chars | ~40 chars | Min 25 chars enforced; hook + outcome beats keyword stuffing |
| Shopify (on-page H1) | none | 50-65 chars | varies by theme | Write a separate feed title (up to 150 chars) for Google Merchant Center |

1. Amazon-style title formula
Product: [name + brief]. Primary keyword: [keyword]. Secondary keywords: [list 2-3].
Generate 8 Amazon titles following the structure: Brand + Product Type + Key Feature + Size/Color + Pack Size.
Rules: <=200 chars (or 125 for apparel, 80 for baby/pet), no all-caps, no promo words ("BEST", "#1"), primary keyword in first 80 chars (the mobile-visible zone).
Output a table: title | char count | which secondary keyword(s) included.2. Etsy title (mobile-first)
Etsy product: [description]. Generate 6 mobile-friendly titles.
Constraints: stay UNDER 70 chars total (2026 soft cap — longer titles lose mobile visibility), first 40-50 chars must carry the punch (mobile crops there), use 2-3 search terms naturally, include a gift / occasion term if relevant.
For each, list the 3 search terms it targets and the occasion it implies.3. Shopify-style title (conversion-first)
DTC Shopify store. Product: [paste 2-sentence description].
Write 5 on-page titles that lead with the customer outcome, not feature jargon.
Example contrast: "Notebook that survives your bag" (outcome) vs "A5 hardcover notebook" (feature).
Each title: outcome phrase + 1 concrete feature hint. 50-65 chars. No exclamation marks.
Then write one expanded Google Merchant Center feed version per title, up to 150 chars, brand + type + attributes front-loaded in the first 70 chars.4. Comparative title for sets / bundles
I sell [item] as singles AND as a 3-pack. Write distinct titles for each SKU that won't cannibalize each other in search.
Single: emphasize gift / trial / first-time buyer.
Pack: emphasize value / household / restock.
Keep the core keyword in both. Output: SKU | title | which buyer intent it captures.5. Title rewrite for thin / weak listings
Below is my current product title (underperforming on CTR). Rewrite 5 different ways.
For each rewrite, give: (a) what changed (keyword position / structure / hook / specificity), (b) one-line hypothesis on why CTR should rise, (c) which metric to watch in the first 7 days.
Current title: [paste]
Category context: [paste]6. Holiday / season variant titles
Base product: [item]. Primary keyword: [keyword].
Generate 4 season-specific title variants for: Christmas, Mother's Day, Back-to-school, Valentine's Day.
Rules: keep core keyword, swap in gift / season language, do not exceed base title's char count.
For each variant, suggest the listing-active window (e.g., "live Oct 15 -> Dec 24").7. Cross-platform title adaptation
Adapt this Amazon title for three platforms. Same product, different conventions and caps:
- Etsy: under 70 chars, gift-focused, occasion-aware
- eBay: <=80 chars, specs/model/size up front
- TikTok Shop: 40-80 chars, hook + outcome, no keyword-stuffing
Amazon title: [paste]
For each platform output: adapted title | char count | which platform convention it follows.8. Title A/B test pairs
Generate 5 A/B title pairs for the product below. Each pair tests exactly ONE variable. State the hypothesis explicitly.
Test variables to choose from: keyword position (front vs back), length (short vs full-cap), benefit-led vs feature-led, with-number vs without-number, brand-first vs product-first.
Output: pair # | variant A | variant B | hypothesis | success metric.
Product description: [paste]9. Long-tail keyword title
Product: [item]. Long-tail keyword research below (paste).
Write 6 titles that each target a different long-tail phrase from the list — not the head term.
Each title: long-tail phrase in first 60 chars + product type + one differentiator.
List which long-tail it targets, monthly search volume, and competition score per title.
Keyword research: [paste]10. Title for a rebrand / repositioning
I'm repositioning [product] from [old positioning] to [new positioning].
Old title: [paste]. Write 5 new titles that signal the new positioning while keeping enough keyword overlap that existing organic traffic doesn't collapse.
For each: which keywords were preserved, which buyer signal changed, expected SEO impact in first 30 days.11. Title for a multi-variant listing (color / size)
Parent product: [item] sold in [N variants: colors / sizes].
Write a parent listing title + 5 child variant titles.
Parent title carries the brand-level keyword. Child titles add the variant attribute up front (e.g., "Navy", "XL") without bloating length.
Show parent and children as a table. Keep child titles <=120 chars.12. Title audit + scoring rubric
Audit this title against a 5-point rubric: (1) primary keyword in first 80 chars, (2) buyer outcome named, (3) under platform char cap, (4) no keyword-stuffing, (5) no promo language banned by platform.
Score each criterion 0-2 with one-line reasoning. Total / 10. Then rewrite to hit 10/10.
Title: [paste]
Platform: [Amazon / Etsy / Shopify / eBay / TikTok Shop]Common mistakes
- Keyword-stuffing past readability. Amazon auto-corrects non-compliant titles after roughly 14 days, and Etsy now lowers mobile visibility for titles over 70 characters.
- Reusing one title across every platform. Etsy buyers, Amazon buyers, and eBay buyers search differently, and the caps range from 80 to 200 characters.
- A/B testing without a stated hypothesis, so you can’t learn from the winner.
- Burying the keyword past the mobile crop point — 40-50 chars on Etsy and eBay, ~80 on Amazon.
- Naming the feature instead of the outcome on a DTC store, where the buyer doesn’t speak your spec language.
FAQ
Which AI model writes the best product titles? For this task the model matters less than the structured prompt. As of June 2026, ChatGPT (GPT-5.5), Claude (Sonnet 4.6), and Gemini 3.1 Pro all produce usable titles. The free tiers are enough for batch title work; the rules and the cap you supply do the heavy lifting.
Why does the AI keep writing titles that are too long? Models don’t count characters reliably. Always include the hard cap in the prompt, ask for a char-count column in the output table, then verify the longest ones yourself. Amazon will auto-correct an over-limit title after about 14 days; Etsy quietly demotes anything past 70 characters on mobile.
Should the Amazon and Shopify titles be identical? No. Amazon rewards keyword depth up to 200 characters, while a Shopify on-page H1 reads best at 50-65 characters with a separate expanded feed title (up to 150 characters) for Google Merchant Center. Prompt 3 generates both versions.
How many title variants should I A/B test at once? Test one variable per pair (Prompt 8). Run a single variable change long enough to clear noise — typically a few hundred sessions or impressions per variant — before declaring a winner, then carry that learning into the next test.
