Affiliate tag management
Save your tag once per program, reuse it on every link, forever.
Every affiliate program you're part of gives you a unique tag — a code that has to be attached to a link before a sale counts as yours. Managing that by hand, program by program, link by link, is where typos live. Affiliate tag management is where you save each tag exactly once.
How it works
Add a tag for a program — Amazon US, Amazon France, Best Buy, eBay, and over a hundred more are recognized automatically — and every new link that points at that program's domain picks it up without you doing anything. It's also what powers Amazon auto-localization and auto-generated country rules: those features can only build a targeting rule for a marketplace you've actually saved a tag for.
Good to know
Changing a saved tag updates it everywhere it's used going forward — you don't need to go back and edit existing links one by one.
