What is a UTM link?

• utm_source — where the visitor came from (google, facebook, newsletter)
• utm_medium — traffic type (cpc, email, social, banner, referral)
• utm_campaign — the campaign name (summer_sale, launch, black_friday)
• utm_term — paid keyword (only for search/paid campaigns)
• utm_content — ad variant / creative differentiator

Once your visitor clicks a UTM-tagged link, Google Analytics 4 attributes their session to the exact source/medium/campaign — no more guessing where your traffic comes from.
