Those errors are because of the unescaped ampersands. Replace & with &, and they'll validate, without causing any major problems. (Browsers are supposed to convert entity references in URIs, so & is "correct"; & is an error that browsers support for backwards-compatibility.)

I've been tweaking tracking and advertising scripts for validation purposes for years, and no tracking or advertising company has ever noticed or complained.
