What's the difference between source, medium, and campaign?

Source is where the traffic comes from (e.g. "newsletter"), medium is the marketing channel type (e.g. "email"), and campaign identifies the specific promotion (e.g. "spring_sale").

Do UTM parameters affect SEO?

No — they're for analytics tracking only and don't affect search rankings, though it's good practice to canonicalize pages so tagged and untagged versions aren't treated as separate URLs.
