UTM Link Builder — Free Campaign URL Generator

UTM parameters are tags added to the end of a URL that tell analytics tools where traffic came from. There are five UTM parameters: utm_source (traffic source like google or newsletter), utm_medium (marketing channel like cpc or email), utm_campaign (campaign name), utm_term (paid search keywords), and utm_content (used for A/B testing or differentiating links). When someone clicks a UTM-tagged URL, the parameters are sent to Google Analytics or similar tools.

Technically, none are strictly required by analytics tools — any UTM parameter present will be recorded. However, best practice is to always include utm_source, utm_medium, and utm_campaign together. Without all three, your analytics reports may show incomplete or misleading data. utm_term and utm_content are optional and used for more granular tracking.

utm_source identifies the specific platform or sender (e.g., google, facebook, mailchimp, partner_blog). utm_medium identifies the marketing channel type (e.g., cpc, email, social, referral). Think of medium as the category and source as the specific entity. For example: utm_source=google&utm_medium=cpc means paid search on Google, while utm_source=google&utm_medium=organic means organic search.

Yes. Google Analytics treats utm_source=Facebook and utm_source=facebook as two different sources. This is a common mistake that fragments your data. Always use lowercase for all UTM values to keep reports clean. Establish a naming convention and document it so your team stays consistent.

No. Adding UTM parameters to links within your own website resets the session attribution in Google Analytics. The original traffic source is overwritten, making it appear that the traffic came from your own site instead of the actual external source. Use UTM parameters only on links that appear outside your website — in emails, social media posts, ads, and partner sites.

Google Analytics recognizes specific utm_medium values for its default channel groupings. Common standard values are: cpc (cost-per-click paid ads), email (email campaigns), social (organic social media posts), referral (partner or third-party links), display (banner ads), affiliate (affiliate links), and organic (organic search, though this is usually auto-tagged). Using these standard values keeps your channel reports organized.

In Google Analytics 4, UTM data appears under Reports > Acquisition > Traffic Acquisition. The Session source/medium dimension shows utm_source and utm_medium combined (e.g., newsletter / email). You can also view utm_campaign under the Session campaign dimension. Use the secondary dimension or exploration reports to see utm_term and utm_content.

Google Ads has its own auto-tagging system (gclid) which is more accurate than manual UTM tagging for Google Ads campaigns. If you enable auto-tagging in Google Ads, you do not need to add UTM parameters — in fact, using both can cause data discrepancies. Use UTM parameters for non-Google ad platforms (Facebook Ads, LinkedIn Ads, etc.) and for organic channels like email and social.

UTM parameters do not directly affect SEO rankings. However, if search engines index UTM-tagged URLs alongside clean URLs, it can create duplicate content issues. To prevent this, ensure your website uses canonical tags pointing to the clean URL (without UTM parameters). Most modern CMS platforms handle this automatically.

Use lowercase, separate words with hyphens or underscores, and include identifiers like date or product. A good pattern is: product_type-date (e.g., widget-pro-launch-2025-q1). Avoid spaces (they become %20 in URLs), special characters, and vague names like campaign1. Document your convention in a shared spreadsheet so all team members use the same format.

There are five standard UTM parameters (source, medium, campaign, term, content). You can include all five in a single URL. While URLs have a practical length limit of about 2,000 characters in most browsers, UTM parameters rarely approach this limit. Keep parameter values concise — shorter URLs are easier to share and less likely to break when copied.

No. All URL building happens entirely in your browser using JavaScript. No URLs, campaign names, or parameter values are sent to any server. When you refresh the page, all inputs are cleared.
