How UTM links work
UTM parameters are small labels added to a URL so analytics tools can identify where a visit came from and which campaign produced it.
The five UTM parameters
Source identifies the platform, medium describes the channel, and campaign names the promotion. Term is useful for keywords and content distinguishes ads or links in the same campaign.

Use UTM links consistently
Use them for social posts, newsletters, advertising, influencer partnerships, and printed QR codes. Values are case-sensitive, so keep a consistent naming convention. Avoid UTM tags on internal navigation because they can overwrite attribution data.
