Free UTM Campaign URL Builder
If your campaign links are not tagged consistently, GA4 splits one campaign across half a dozen rows and the reporting stops being useful. This free UTM builder appends utm_source, utm_medium, utm_campaign, utm_term, utm_content, and utm_id to any destination URL, normalises casing and spaces so your naming stays uniform, preserves existing query strings and fragments, and gives you a copy-ready link in seconds.

Frequently asked questions
Which UTM parameters are required?
utm_source, utm_medium, and utm_campaign. Without all three, GA4 cannot attribute the session to your campaign and the traffic usually lands in a generic referral or direct bucket.
Do UTM parameters hurt SEO?
Not when used on campaign links you share externally. Avoid putting UTM tags on internal navigation links, and make sure tagged URLs canonicalise to the clean version so search engines index one URL.
