Tiny Tools › URL parameter glossary › mkrid
mkrideBay's marketing rotation ID — identifies the specific campaign or placement "rotation" behind a click, alongside mkevt and mkcid. It's there for eBay's attribution reporting and has no effect on the page you land on.
Safe to remove? Yes. mkrid is used for tracking and reporting only — deleting it does not change the page you land on. Strip it before sharing a link to keep it clean and private.
