dib
What is dib in an Amazon URL?
What dib looks like
Open a product from Amazon's search results and the address grows a long parameter: dib=eyJ2IjoiMSJ9. followed by a few hundred characters. The first segment is readable — eyJ2IjoiMSJ9 is Base64 for {"v":"1"}, a version marker — and the rest is not. Next to it sits dib_tag=se.
Amazon publishes no description of either. They began appearing on search-result links and are treated as tracking by the people who maintain cleaning rules: Firefox added dib, dib_tag and crid to its Copy Link Without Site Tracking list for Amazon in October 2024.
The search context around it
dib is one of several parameters that only appear when you arrive from a search. qid is a query id and sr the rank of the result you clicked (sr=8-3 is the third result). crid identifies the autocomplete session, and sprefix contains what you had typed when you picked a suggestion.
Put together, a product link copied from a search says what you searched for, what you had typed first, and which result you chose. The person you send it to only needed the product.
What LinkClean keeps
th= and psc= select the variant — the size or colour you were looking at — so they survive. k= is the query on a search page and stays too.
LinkClean cleans the query string. The /ref=… segment Amazon writes into the path is not a query parameter and is left as it is.
How LinkClean removes it
Default-on, scoped to Amazon's storefront domains. The same names on other sites are untouched. For the whole procedure see How to clean an Amazon product link.
Frequently asked
What does dib stand for?
Amazon has not said. Nothing in its public documentation expands or explains the name.
What does dib_tag=se mean?
It is undocumented. The value se is the one seen on links opened from search results, which is consistent with it naming the surface the click came from — an inference, not a published fact.
Does removing dib break the product link?
No. The product is addressed by the ASIN in the path, after /dp/.
Why keep th= and psc=?
Because they are functional. They choose which variant of the product the page opens on, and removing them can land the reader on a different size or colour.
Clean tracking on iPhone, in one tap.
LinkClean strips 250+ vendor-specific tracking parameters from any link, from any app's share sheet — and preserves functional ones like hl, t (YouTube timestamp), and q (search). No account, on-device.
