Google Analytics URL Builder

Only the destination URL is required to get a result. Source, medium, and campaign are the three parameters GA relies on most for attribution, so fill those in too — term and content are optional, used mainly for paid-search keyword and ad-variant tracking.

Source is where the traffic comes from (e.g. google, newsletter, facebook); medium is the marketing channel type (e.g. cpc, email, social). Campaign is your own name for this specific push (e.g. summer-sale).

Yes — utm_source/medium/campaign/term/content are the same standard parameters GA4 reads for campaign attribution; this tool just appends them to your URL.

No, it appends the parameters you enter without checking for existing ones — if your URL already has UTM tags, review the output before using it to avoid duplicated or conflicting parameters.
