eBay referrer traffic

eBay is a global marketplace for new and used goods. Links a seller places in listings or a store profile can drive external traffic that sometimes carries an ebay.com referrer, but the eBay app and outbound-link handling frequently strip it. This page explains what an eBay referrer means and how UTM tags keep marketplace-driven visits measurable.

What an eBay referrer represents

eBay lets sellers maintain stores, listings, and profiles. Permitted outbound links from those surfaces to an external site can generate clicks carrying an ebay.com referrer when navigation preserves it — most reliably on desktop web.

A large share of eBay activity happens in its mobile apps, where outbound taps commonly send no HTTP referrer, and marketplaces may redirect or wrap outbound links. As a result, referrer-based reporting understates how much traffic actually originated on eBay.

Measuring eBay-driven traffic

For links you control on eBay surfaces, add UTM parameters so the click is attributed even without a referrer. Use utm_source=ebay and a utm_medium describing the placement, such as marketplace.

The query string survives app navigation and most redirects, so tagged eBay links are counted as eBay regardless of whether the referrer arrives. Untagged links fall into direct, hiding the marketplace's real contribution.

How it appears in analytics and logs

An ebay.com referrer means a visit came from an eBay page that preserved the referrer, usually desktop web. App navigation and redirected outbound links often arrive with no referrer, so eBay's real contribution is typically higher than the report indicates.

Diagnostic use case

Understand why external traffic from eBay listings or a store is undercounted in referrer reports, and tag eBay-placed links so the source is reliable.

What WebmasterID can help detect

WebmasterID records the referrer the browser sends and reads UTM parameters on eBay-placed links, so marketplace-driven external traffic is attributed correctly even when the referrer is stripped.

Common mistakes

Privacy and accuracy notes

A missing referrer from a marketplace app is normal browser behaviour, not a failure. WebmasterID reads the referrer when present and never re-identifies a visitor when it is absent.
