Crunchbase referrer traffic
Crunchbase is a database of companies, funding, and people. A link from a company's Crunchbase profile to its website can carry a crunchbase.com referrer, but referrer-policy trimming and outbound-link handling can reduce it to the bare host or strip it. This page explains what the referrer means and how to tag profile links for reliable attribution.
What a Crunchbase referrer represents
Crunchbase aggregates company, funding, and people data, and each company profile can link out to the company's own website. A click on that outbound link can carry a crunchbase.com referrer when navigation preserves it.
Many platforms apply a referrer policy that sends only the origin rather than the full path, so you may see crunchbase.com without the specific profile URL. Outbound links may also be configured in ways that drop the referrer entirely, leaving some profile clicks as direct.
- Outbound profile links can drive crunchbase.com referrers
- Referrer policy may trim the path to the bare origin
- Some outbound configurations drop the referrer entirely
Measuring Crunchbase-driven traffic
Where you can set the destination of your Crunchbase profile link — the website field is yours to define — append UTM parameters so the click is attributed regardless of how the referrer is trimmed. Use utm_source=crunchbase and a utm_medium such as profile or referral.
The query string is unaffected by referrer-policy trimming, so tagged profile links remain attributable even when only the origin (or nothing) arrives as a referrer. Untagged profile clicks may collapse into a generic host referral or direct.
How it appears in analytics and logs
A crunchbase.com referrer means a visit came from a Crunchbase profile. Depending on the platform's referrer policy, you may receive only the origin (crunchbase.com) rather than the full profile URL, and some outbound clicks may carry no referrer at all.
Diagnostic use case
Understand why traffic from a company's Crunchbase profile may show only the host or arrive as direct, and tag the profile link so investor and research traffic is measurable.
What WebmasterID can help detect
WebmasterID records the referrer the browser sends — full URL or origin-only — and reads UTM parameters on a Crunchbase profile link, so company-profile traffic is attributed accurately even when the referrer is trimmed.
Common mistakes
- Expecting a full profile URL when the referrer policy sends only the origin.
- Leaving the Crunchbase website field link untagged.
- Treating origin-only or absent referrers as a measurement bug.
Privacy and accuracy notes
A trimmed or absent referrer is a deliberate browser/site privacy behaviour, not a tracking failure. WebmasterID reads the referrer when present and never re-identifies a visitor when it is absent.

Wellfound, formerly AngelList Talent, is a startup jobs and company platform. Links from a company profile or job post to an external site can show a wellfound.com referrer, but app navigation and outbound-link handling often strip it. This page explains what the referrer means and how to tag Wellfound-placed links for reliable attribution.
- Referrer-Policy and missing referrers
Referrer-Policy is the web standard that controls how much of the referrer a browser sends with a request. Site owners set it via an HTTP header or a meta tag, and modern browsers default to a privacy-leaning value. Understanding the policy values explains why so many referrers arrive trimmed to the origin or missing entirely.
- LinkedIn referrer traffic
LinkedIn is a common B2B traffic source, but its lnkd.in link shortener and the in-app browser used on mobile frequently strip the web referrer. Visits then land in direct, undercounting LinkedIn. Because LinkedIn audiences often matter for B2B attribution, UTM tagging is the reliable way to measure them.
- Campaign links
Tag your Crunchbase profile link so profile traffic stays attributable despite referrer trimming.
