By adding UTM parameters to your quiz URLs, you can: * Identify where your traffic comes from * Pre-fill quiz fields with known user data * Customize the quiz experience dynamically * Improve campaign attribution in analytics In this guide, you’ll learn how to use UTMs effectively with Quizell — including advanced personalization, multiple parameters, hidden UTMs, and embed use cases. ${youtube}[Personalizing Your Quiz with UTM Parameters](OxrLExOrD4Q) ## **Using UTM Parameters: Practical Examples** ### **1. Pre-filling User Details** If you’re sending a quiz via email and already know the user’s information, you can pre-fill fields automatically. **Example:** ``` https://app.quizell.com/quiz/QuizID?utm_full_name=John+Doe&utm_email=john.doe@example.com ``` ### **2. Tracking Traffic Sources** Use UTMs to identify where quiz participants come from — ideal for social media, paid ads, newsletters, influencers, and more. **Example:** ``` https://app.quizell.com/quiz/QuizID?utm_source=facebook&utm_medium=social&utm_campaign=summer_sale ``` This data appears in your Quizell analytics so you know which channels perform best. ### **3. Customizing Your Quiz Loader** UTMs can also modify visual elements like your quiz loader. Use the `loader` parameter to set the loader type and its colors. **Example:** ``` https://app.quizell.com/quiz/QuizID?loader=4~000000~ffffff ``` For the full list of loader types and color options, check out our [guide on customizing quiz loaders](https://help.quizell.com/en/article/how-to-customize-your-loader-10jfate/). ## **Adding Multiple UTM Parameters** You can combine as many UTMs as you need — just separate them with &. **Example with multiple parameters:** ``` https://app.quizell.com/quiz/QuizID?utm_full_name=John+Doe&utm_email=john.doe@example.com&utm_source=facebook&utm_campaign=quiz_launch ``` ## **Passing UTMs Through an Embed Code** If you’re embedding your quiz on a website, UTMs must be passed dynamically into the embed through JavaScript. **Simplified example:** ``` ``` 💡 This ensures UTMs carry over even if the quiz is embedded inside a landing page, a popup, or a CMS like Wix, WordPress, or Webflow. ## **Using Hidden UTMs (Tracking Without Showing Users)** Sometimes you want to track a source without showing any visible fields to the user — for example, adding a “utm\_source” that appears only in analytics. You can do this by simply **passing the UTM in the URL** without mapping it to a visible field. **Example:** ``` https://app.quizell.com/quiz/QuizID?utm_source=facebook_ads ``` Because it is not mapped to a quiz field, the user does not see it — but Quizell still captures the UTM in your analytics dashboard. This is useful for: * Tracking paid ad performance * Tracking influencer or affiliate links * Measuring blog/SEO traffic * A/B testing campaigns If you want to use UTMs for personalization **without exposing them**, simply avoid assigning them to visible quiz content. ## **Adding UTM Parameters to Your Quiz URL** ### **Step 1: Copy Your Quiz Link** 1. Open the quiz you want to share. 2. Click **Share**. 3. Copy the quiz link. ### **Step 2: Append Your UTMs** Add your parameters at the end of the link: **Example:** ``` https://app.quizell.com/quiz/RJ7hfCOawFhKlJkHKOD6MS178500?utm_email=john.doe@example.com ``` Here, the parameter `utm_email=john.doe@example.com` automatically fills the email field with john.doe@example.com. ![](https://storage.crisp.chat/users/helpdesk/website/-/9/c/4/e/9c4e823823ced00/screenshot-2025-09-29-at-10031_1w1jdf1.png =1000x611) ## FAQ **Q: How many UTM parameters can I use?** There is no strict limit, but keep URLs manageable. Use only what you need. **Q: Are UTM parameters case-sensitive?** Yes — enter parameter names exactly as shown (lowercase), so `utm_email` works as expected. **Q: Can UTMs pre-fill custom inputs?** Yes — you can pre-fill any custom field by using the parameter name: ``` ?utm_custominput=value ``` **Q: Can I hide UTMs from users?** Absolutely. Any UTM you don't map to a visible field remains hidden and is used for analytics only. ## UTM Parameters for Personalization Here are examples of UTM parameters you can use to enhance personalization: | Parameter | Example Implementation | | Full Name | `?utm_full_name=John+Doe` | | Email | `?utm_email=john.doe@example.com` | | Phone number | `?utm_phone_number=1234567890` | | Website url | `?utm_website=https://example.com` | | Organization | `?utm_organisation=ExampleCorp` | | Terms & Condition | `?utm_checkbox=true` | | Custom Input | `?utm_custominput=specificValue` | | Address Line 1 | `?utm_address_1=350+5th+Avenue` | | Address Line 2 | `?utm_address_2=Suite+3400` | | City/Town | `?utm_city=New+York` | | State/Region/Province | `?utm_state=NY` | | Country | `?utm_country=United+States` | | Zip/Post Code | `?utm_zip_code=10118` | | Loader | `?loader=4~000000~ffffff` | ## Conclusion By using UTM parameters, you can: * Deliver highly personalized quiz experiences * Track campaign performance with precision * Pre-fill fields to reduce friction * Customize the quiz appearance * Collect deeper insights into your audience Whether you’re running ads, sending emails, or embedding quizzes in your website, UTMs give you the power to optimize and personalize your funnel. ## **What’s Next?** Explore more ways to personalize and optimize your quizzes: * [Guide on Customizing Quiz Loaders](https://help.quizell.com/en/article/how-to-customize-your-loader-10jfate/) * [Adding Dynamic Content to Your Thank You and Result Pages](https://help.quizell.com/en/article/how-to-add-dynamic-content-to-your-result-and-thank-you-pages-1xcwk8g/) * [How to Personalize Quiz Content Using User Data](https://help.quizell.com/en/article/how-to-personalize-quiz-content-using-user-data-in-quizell-15lev1j/) * [How to Build a Personality Quiz](https://help.quizell.com/en/article/how-to-build-a-personality-quiz-using-quizell-10zx08t/) * [How to Connect Quizell to Klaviyo](https://help.quizell.com/en/article/how-to-connect-klaviyo-to-your-quizell-account-1xcif1i/)
