UTM Builder FAQ.
What is a UTM builder?
A UTM builder (also called a URL builder or campaign link generator) is a tool that appends UTM tracking parameters to any URL. These parameters tell Google Analytics, GA4, and other analytics platforms exactly where your traffic came from — which source, medium, and campaign drove each visit.
What are UTM parameters?
UTM parameters are five tracking tags added to the end of a URL: utm_source (e.g. google, newsletter), utm_medium (e.g. cpc, email), utm_campaign (e.g. summer_sale), utm_content (e.g. banner_v1), and utm_term (e.g. running+shoes). They were originally developed by Urchin, which Google acquired to build Google Analytics.
Why are UTMs important for marketers?
UTMs give you surgical visibility into which campaigns, channels, and creatives are actually driving conversions. Without them, GA4 groups most traffic under 'direct' or '(not set)', making it impossible to measure marketing ROI accurately.
What is the difference between utm_source and utm_medium?
utm_source identifies who sent the traffic (e.g. google, facebook, mailchimp). utm_medium describes the marketing channel type (e.g. cpc, email, social, organic). Think of source as the publisher and medium as the delivery method.
How do I track UTM parameters in GA4?
In Google Analytics 4, go to Reports → Acquisition → Traffic Acquisition. The default channel grouping already reads UTM data. For a custom breakdown, use Explore → Free Form and add 'Session source', 'Session medium', and 'Session campaign' as dimensions.
Are UTM parameters case-sensitive?
Yes. 'Email', 'email', and 'EMAIL' appear as three separate mediums in your analytics reports. Always use lowercase and hyphens instead of spaces to keep your data clean (e.g. utm_campaign=summer-sale).
Do UTM parameters affect SEO?
UTM parameters do not directly impact your search rankings. However, you should set a canonical URL on pages that could be accessed with UTM parameters to prevent duplicate content issues. BlinkURLs automatically handles this by shortening your UTM links.
Can I use a UTM link builder for Facebook and Google Ads?
Yes. For Google Ads, use utm_source=google&utm_medium=cpc and enable auto-tagging (gclid) for full integration. For Facebook Ads, use utm_source=facebook&utm_medium=paid_social. You can also use dynamic parameters like {campaign.name} in Facebook's URL builder.
What is utm_content used for?
utm_content is used for A/B testing and differentiating between multiple links in the same campaign. For example, if you have two banner ads in one email, use utm_content=banner_top and utm_content=banner_bottom to see which one gets more clicks.
Does BlinkURLs track UTMs?
Yes. When you shorten a UTM link with BlinkURLs, we preserve all your UTM parameters and add our own real-time click analytics on top — giving you two layers of tracking: your analytics platform (GA4) and BlinkURLs' own dashboard.
