Title length by marketplace
Every marketplace counts differently, and the hard limit is rarely the number that matters — titles get visually truncated long before they get rejected.
| Marketplace | Hard limit | Displays fully up to | Notes |
|---|---|---|---|
| Amazon | 200 | 80 | Many categories enforce 80 or fewer; over-length titles get suppressed from search. |
| eBay | 80 | — | |
| Etsy | 140 | — | |
| Google Shopping | 150 | 70 | Truncated in ads beyond ~70. |
| Walmart | 200 | 75 | |
| Shopify (SEO title) | 70 | — | Google truncates page titles around 60–70 characters. |
Limits collected 2026-08-22 and shown as a guide. Marketplaces change them, and Amazon in particular enforces stricter limits in many categories — confirm in your seller dashboard.
The characters you cannot see
Titles copied from supplier spreadsheets and translation tools carry passengers: zero-width
spaces, non-breaking spaces, full-width Latin letters that look identical to normal ones, and
leftover CJK punctuation. They are invisible in your editor but stored in the listing, where
they break exact-match search and stop your own SKU lookups from matching. This checker shows
them as ␣ so you can find them.
Why ALL CAPS gets listings suppressed
Marketplace style guides prohibit gratuitous capitalisation, and enforcement is automated. Acronyms are fine — USB, LED, XL — which is why this tool only flags capitalised words longer than three letters rather than shouting about every capital.
Every check this tool runs (16 rules)
Length
TTL-L01 Over the marketplace title limit
The title exceeds the maximum length for at least one selected marketplace. Over-length titles are rejected or suppressed from search results rather than simply trimmed.
Fix: Put the words buyers search for first, then cut from the end: redundant adjectives, repeated brand mentions, and packaging trivia.

TTL-L02 Longer than the recommended display length
The title fits the hard limit but exceeds the length that actually displays in search results — the tail gets cut mid-phrase on mobile.
Fix: Front-load the essentials: brand, product type, the one attribute that differentiates it.

TTL-L03 Very short title
Under 20 characters gives search engines almost nothing to match against. Titles this short usually omit the product type or key attributes buyers type.
Fix: Add the product type and one or two defining attributes (size, material, quantity).

Capitalisation & typography
TTL-C01 ALL CAPS words
Gratuitous capitalisation is prohibited by most marketplace style guides and is a frequent cause of listing suppression. Acronyms (USB, LED, XL) and single letters are fine.
Fix: Use title case: capitalise the first letter of each significant word.

TTL-C02 Title is entirely lowercase
An all-lowercase title reads as unfinished data rather than a product name, and some marketplaces normalise it inconsistently across surfaces.
Fix: Use title case.

TTL-C03 Repeated punctuation or decorative separators
Runs like "!!!", "***", "~~~" or "|||" are treated as promotional decoration. They consume length, are not searched for, and violate style guides.
Fix: Use a single separator (a comma or a hyphen) between phrases.

Characters
TTL-X01 Emoji or pictographic characters
Emoji are not permitted in marketplace titles. They also cost 4 bytes each and are never typed by buyers in search.
Fix: Remove the emoji.

TTL-X02 Trademark or copyright symbols
Most style guides prohibit ™, ® and © in titles — they are not searchable and cause rejections on several marketplaces.
Fix: Remove the symbol; the brand name alone is sufficient.

TTL-X03 Invisible or zero-width characters
Zero-width spaces, non-breaking spaces and BOM markers are invisible in your editor but become part of the stored title, breaking exact-match lookups and sometimes word splitting.
Fix: Retype the affected part of the title.

TTL-X04 Full-width characters
Full-width Latin letters and digits (ABC, 123) arrive from CJK input methods. They look almost identical to normal characters but never match what buyers type.
Fix: Convert them to standard half-width characters.

TTL-X05 Characters from another writing system
CJK, Cyrillic, Arabic or other non-Latin characters in a title meant for an English-language marketplace are almost always leftovers from translation or a supplier spreadsheet — including the CJK comma "," and full-width brackets.
Fix: Replace them with their English equivalents.

Wording & content
TTL-W01 Promotional or pricing text
Titles must describe the product, not the offer. "Free shipping", "sale", "best price", "% off", "hot deal" and similar phrasing are prohibited across marketplaces and are a common suppression trigger.
Fix: Move promotional messaging into a promotion or the description.

TTL-W02 Subjective claim
Subjective superlatives ("best", "amazing", "perfect", "#1") carry no search value and are prohibited by most style guides. Buyers search for attributes, not adjectives.
Fix: Replace with a concrete attribute: material, capacity, compatibility, certification.

TTL-W03 Repeated word
A word repeated in the title wastes length without improving matching — marketplaces index each word once.
Fix: Remove the repetition and spend the characters on an attribute you have not mentioned yet.

TTL-W04 Contact details or external links
Phone numbers, email addresses and URLs in a title violate every marketplace policy and can lead to account-level enforcement, not just a rejected listing.
Fix: Remove them entirely.

TTL-W05 Placeholder or template text
The title contains leftover template content ("{{product_name}}", "TBD", "N/A", "test", "lorem ipsum"). These reach live listings surprisingly often.
Fix: Replace with the real product title.
