About the utm builder
A UTM builder appends standardized `utm_source`, `utm_medium`, `utm_campaign`, `utm_term` and `utm_content` parameters to a link so Google Analytics (GA4) attributes the click to the right campaign. Consistent UTM tagging is the difference between knowing a newsletter drove signups and guessing. Use this UTM builder (also called a campaign URL builder) for emails, paid ads, social posts and partnerships.
Frequently asked questions
Is this tool free?
Yes — completely free, no signup, no watermark and no limits. Startup OG funds the site through its directory and partner program, not paywalled tools.
What is a UTM parameter?
A UTM parameter is a tag added to a URL (e.g. `?utm_source=newsletter&utm_medium=email`) that analytics tools read to group traffic by campaign. UTM stands for Urchin Tracking Module.
Which UTM parameters are required?
Source, medium and campaign are the three you should always set for clean reporting. Term and content are optional — term is usually a paid keyword, content distinguishes A/B variants.
Should UTM values be lowercase?
Yes. Analytics treats `Email` and `email` as different values, so pick a lowercase, hyphenated convention and stick to it to avoid fragmented reports.
