Frequently Asked Questions
A UTM builder is a free online tool that adds tracking parameters to any URL so you can see exactly where your website traffic comes from in Google Analytics. Instead of manually typing ?utm_source=newsletter&utm_medium=email into a link, you fill in a form and the tool builds the URL for you.
The five UTM parameters are: utm_source (where traffic comes from, e.g. 'google' or 'newsletter'), utm_medium (the marketing channel, e.g. 'cpc' or 'email'), utm_campaign (the campaign name), utm_term (keyword for paid search), and utm_content (to differentiate ads or links in the same campaign). Source, medium, and campaign are required; term and content are optional.
No. Adding UTM parameters to links within your own website overwrites the original traffic source in GA4, making it look like traffic came from your own site instead of the original source. UTM parameters should only be added to links in emails, ads, social media posts, and external partner content.
No. UTM parameters have no effect on your search engine rankings. They are stripped from URLs before Google indexes the page and are only read by analytics platforms like Google Analytics 4.
utm_source identifies the specific platform or publisher sending traffic (e.g. 'facebook', 'mailchimp', 'google'). utm_medium identifies the type of marketing channel (e.g. 'social', 'email', 'cpc'). Think of source as the 'who' and medium as the 'how'.
