What it does
`bcookie` identifies a browser to LinkedIn. It arrives with `bscookie` for secure contexts, `lidc` for routing, `li_sugr` for probabilistic matching, and `UserMatchHistory` and `AnalyticsSyncHistory` for identifier synchronisation.
The Insight Tag also writes first-party identifiers through the page (`ln_or` and `_lc2_fpi`), which a domain-based audit would attribute to your own site.
What to write in a cookie declaration
Declare the LinkedIn set as a group with LinkedIn named as provider, and include the first-party ones. The group is long enough that omitting half of it is noticeable.
| Field | Value |
|---|---|
| Name | bcookie |
| Provider | |
| Purpose category | advertising |
| Consent category | Marketing |
| Expiry | 1 year (vendor default) |
| Storage | Third-party |
Treat the expiry as indicative
The value above is the vendor’s documented default. Vendors change configuration and several browsers cap script-written lifetimes. Record what repeated scans observe on your own site, with the browser, region, path and interaction state; one run is not authoritative for every visitor.
Can a visitor refuse it?
Yes, in marketing. There is no named adapter, so gate the Insight Tag as a custom script or as a container tag with a consent setting.
A verification scan supplies runtime evidence for the pages and states it exercises. Test a fresh profile with no choice made, then after refusal, and reconcile observed storage with response headers, server-side integrations and paths the scan did not visit.
Common questions
Why does LinkedIn set so many cookies?
Because the tag serves several purposes at once: identification, routing, matching and synchronisation with LinkedIn’s advertising systems. Each has its own cookie.

They support the stated facts, not a legal conclusion for every site or configuration; recheck changing vendor behaviour before relying on it in production.

A browser scan reports the requests and storage it observed during the sampled journey. Use configured workspace scans to compare the states and pages that matter to your implementation.
