Bing
What it is
Microsoft's search engine. Bing result links point at a click-tracking address, www.bing.com/ck/a?..., which forwards the visitor to your page.
Why there's no full URL
Bing sets an origin-when-cross-origin policy, so other sites get only https://www.bing.com/ and never the query or the /ck/a path.
What traffic it represents
Organic and other clicks from Bing search results.
