dchild
What is dchild=1 in an Amazon URL?
What dchild looks like
It sits among the search parameters of a product link: …/dp/B0TEST1234?dchild=1&keywords=usb+c&qid=1700000000&sr=8-3. The value is nearly always 1.
Amazon publishes no description of it. A common reading is that it marks the product as a child variation, one size or colour of a parent listing, reached from search. That is an inference from the name. The page shown does not change when it is removed.
What it travels with
qid and sr record the search and the rank of the result you clicked, crid and sprefix the autocomplete session, and dib the result slot. LinkClean removes those on Amazon as well. refRID, the request id of the page that linked to the product, goes with them.
What LinkClean keeps
th= and psc= select the variant you were looking at, so they stay. keywords= and k= are the search query and stay too. Several public strip lists remove keywords; LinkClean does not, because on a search page it is the search.
How LinkClean removes it
Default-on, scoped to Amazon's storefront domains. ClearURLs, AdGuard's filter and Firefox strip dchild on Amazon too. For the whole procedure see How to clean an Amazon product link.
Frequently asked
What does dchild=1 mean?
Amazon has not said. The name suggests it marks a child variation of a product, which is an inference and not a published fact.
Does removing dchild change the product shown?
No. The ASIN in the path picks the product, and th= and psc= pick the variant.
Is dchild an affiliate parameter?
No. The affiliate ID on an Amazon link is tag=. dchild appears on ordinary search-result links.
