Original research from the supply side
The words 1688 English titles repeat
In this non-random sample, 72 of 120 API-returned English title fields repeated one token at least three times.
Repeated words do not prove seller keyword stuffing. The API does not identify who authored the wording or why it was produced.

API-returned English title fields repeated one token at least three times
The word pattern is illustrative, not a sampled title. Public evidence omits title text to avoid exposing brand, shop or product wording.

What we found
Repetition was common in this draw, but its cause remains unknown
The API returned both subject and subjectTrans on all 120 sampled rows. Under the published tokenisation rule, 72 subjectTrans values repeated one token at least three times and 31 repeated one at least four times. The maximum observed repeat count was 6.
The median subjectTrans length was 124 characters, while the median subject length was 31. Character counts across writing systems are not directly comparable, so this page does not convert that difference into a bloat or translation claim.
The public evidence retains only derived measurements, not title text. That protects brand, shop and product wording, but it also means a reader cannot re-tokenise these exact titles from the public file. The sampling script and metric definition are published so the method can be repeated against a later live draw.
120 of 120 subjectTrans values returned zero CJK characters. This rules out only one visible residue pattern in this draw. It does not establish that the English wording was accurate, complete, fluent or useful.
The official 1688 schema labels subject as the Chinese title and subjectTrans as the foreign-language title. It does not identify who authored the wording, what translation process produced it, or whether a website or app rendered the same value.
Search position is retained only to document the first-page sampling frame. No test links token repetition to rank, clicks, conversion or platform-reported sales.
Before payment
Use the title as a clue, then verify the product itself
Treat an API-returned title as a discovery clue, not a product specification. Extract the exact product, material, size, variant and packaging you intend to buy, then confirm those details in structured attributes and a written supplier response.
Repeated words do not make an offer unsafe or a supplier unreliable. They are a reminder to move critical claims out of the title and into product-specific evidence that can be checked against the exact SKU and destination market.
If the title contains a compliance, performance or material claim, request the applicable document and confirm that it belongs to the product and market in question. This study validates none of those claims.
“Not a translation score — a character-residue check.”
Research boundary
What this study cannot tell you
- BoundaryIt cannot establish what a rendered 1688 website, app or other API surface displayed. The study measured fields returned by one read-only keyword-search API.
- BoundaryIt cannot distinguish seller-authored wording from platform or other localization behavior, so it cannot assign intent or call the pattern seller keyword stuffing.
- BoundaryZero CJK residue does not establish translation accuracy, completeness, fluency or buyer comprehension.
- BoundaryThe study did not test ranking, clicks, conversion, sales or platform algorithms.
- BoundaryThe 120 rows are not 120 distinct suppliers. Seller identity was not retained, so one shop may be represented more than once.
Questions readers ask
Read the finding without over-reading it
What is the one-line finding?
In a Supplymo non-random sample of 120 first-page API result rows from 12 selected English searches on 1688, 72 subjectTrans title fields repeated the same English token at least three times; all 120 returned zero CJK characters, a character-residue check that does not assess translation accuracy or fluency. The threshold is descriptive and does not identify authorship, intent, search strategy or title quality.
Does this prove sellers stuffed keywords into their titles?
No. The API fields do not identify who authored the wording or how it was produced. Repeated tokens can also occur in legitimate multi-use product descriptions.
Does zero CJK residue mean the English translation was good?
No. All 120 subjectTrans fields returned zero CJK characters, but that narrow residue check does not assess accuracy, completeness, fluency or suitability for a buyer.
Did repeated words improve search rank or sales?
The study did not test ranking, clicks, conversion or sales effects. Rank position only defines the first-page sampling frame.
Were these 120 different suppliers?
No. The internal raw sample contained 120 distinct offer IDs, but no seller identity was retained. One seller may therefore appear more than once, and the public file cannot be de-duplicated by shop.
