About the UTM Link Builder
UTM parameters are tags added to a link so analytics tools such as Google Analytics can tell which campaign, newsletter or social post sent a visitor. Enter your page URL and campaign details and the builder produces a correctly encoded tracking link, keeping any query parameters and #fragment already in your URL.

Frequently asked questions
Which UTM parameters are required?
utm_source, utm_medium and utm_campaign are the core trio that Google Analytics recommends. utm_term (paid keywords) and utm_content (to tell apart links or ad variants) are optional.
Should UTM values be lowercase?
Yes, it is best practice. Analytics treats "Facebook" and "facebook" as different sources, so pick a consistent lowercase naming convention.
Can I use UTM links on my own website?
Avoid it. UTM tags on internal links start a new session and overwrite the original traffic source. Use them only for links from external places.
