<\/span><\/h4>\nIf you want to match URLs that contain specific query parameters, regex is useful for capturing these patterns. For example, to match any URL that contains the parameter utm_campaign<\/code>:<\/p>\n\n- Regex<\/strong>:
\\?utm_campaign=.*<\/code><\/li>\n- Explanation<\/strong>: This matches any URL that has
?utm_campaign=<\/code> followed by any sequence of characters (i.e., any value for the utm_campaign<\/code> parameter).<\/li>\n<\/ul>\n<\/span>Example 4: Match URLs with Optional Query Parameters<\/span><\/h4>\nYou can also use regex to match URLs with optional query parameters. For instance, if you want to match all URLs that either have or don\u2019t have a ref<\/code> parameter:<\/p>\n\n- Regex<\/strong>:
^\/landing-page(\\?ref=[a-zA-Z0-9_-]+)?$<\/code><\/li>\n- Explanation<\/strong>: This matches the
\/landing-page<\/code> path with or without the ref<\/code> parameter. The (\\?ref=[a-zA-Z0-9_-]+)?<\/code> portion makes the ref<\/code> parameter optional.<\/li>\n<\/ul>\n<\/span>Step 3: Using Regex in GTM Triggers<\/span><\/h3>\nTo apply regex in your triggers, follow these steps:<\/p>\n
\n- Open the Trigger Configuration<\/strong>: If you’re creating a new trigger, after selecting the trigger type (e.g., Page View<\/strong> or Click<\/strong>), click on the Choose a variable<\/strong> dropdown.<\/li>\n
- Select “Page URL”<\/strong>: For page-related triggers, select Page URL<\/strong> as the variable. For click-related triggers, you can use Click URL<\/strong> or other click-related variables depending on your needs.<\/li>\n
- Select “Matches Regex”<\/strong>: From the condition dropdown, select Matches Regex<\/strong>. This tells GTM that you are using a regular expression for pattern matching.<\/li>\n
- Enter Your Regex Pattern<\/strong>: In the text field, enter your regular expression (for example, the patterns shown in the examples above).<\/li>\n
- Save the Trigger<\/strong>: Once your regex is set up, click Save<\/strong>.<\/li>\n<\/ol>\n
<\/span>Step 4: Create a Tag to Fire Based on Your Trigger<\/span><\/h3>\nAfter setting up the trigger, you can create a tag that fires when the trigger condition is met.<\/p>\n
\n- Create a New Tag<\/strong>: In the left sidebar, click Tags<\/strong> and then New<\/strong>.<\/li>\n
- Choose Tag Type<\/strong>: Select a tag type, such as Google Analytics<\/strong> or Custom HTML<\/strong> depending on your needs.<\/li>\n
- Configure Tag<\/strong>: Set up your tag, specifying details like event category, action, or any other necessary information (for example, track page views in Google Analytics).<\/li>\n
- Set Trigger for Tag<\/strong>: Under the Triggering<\/strong> section, select the trigger you created using regex.<\/li>\n
- Save and Publish<\/strong>: Once you\u2019re satisfied with the configuration, click Save<\/strong> and Publish<\/strong> to apply the changes.<\/li>\n<\/ol>\n
<\/span>Step 5: Testing Your Regex Setup<\/span><\/h3>\nBefore your tag is live, it\u2019s important to test if everything works correctly.<\/p>\n
\n- Preview Mode<\/strong>: Click Preview<\/strong> in GTM to enter debug mode. Enter the URL of your website and verify that the trigger fires as expected when visiting URLs that match your regex.<\/li>\n
- Use GTM Debug Panel<\/strong>: Once in preview mode, you can interact with the website. In the GTM debug panel at the bottom of the screen, you\u2019ll see a list of tags that have fired based on the triggers you\u2019ve set up.<\/li>\n
- Use Google Analytics Real-Time Reports<\/strong>: If you’re using Google Analytics, you can also monitor the Real-Time<\/strong> events to see if your tag is firing when expected.<\/li>\n<\/ol>\n
<\/span>Step 6: Advanced Regex Examples<\/span><\/h3>\nHere are some advanced regex patterns you can use in Google Tag Manager:<\/p>\n
<\/span>Example 1: Match URL with Multiple Parameters<\/span><\/h4>\nIf you want to match URLs with multiple query parameters, such as utm_source<\/code> and utm_medium<\/code>:<\/p>\n\n- Regex<\/strong>:
\\?utm_source=[a-zA-Z0-9_-]+&utm_medium=[a-zA-Z0-9_-]+<\/code><\/li>\n- Explanation<\/strong>: This will match URLs like
\/page?utm_source=google&utm_medium=cpc<\/code>.<\/li>\n<\/ul>\n<\/span>Example 2: Match URLs with a Specific File Extension<\/span><\/h4>\nTo match URLs ending in .pdf<\/code> or .jpg<\/code>:<\/p>\n\n- Regex<\/strong>:
\\.(pdf|jpg)$<\/code><\/li>\n- Explanation<\/strong>: This will match any URL that ends with
.pdf<\/code> or .jpg<\/code>.<\/li>\n<\/ul>\n<\/span>Conclusion<\/span><\/h3>\nRegex in Google Tag Manager provides powerful capabilities for tracking and managing events based on complex URL patterns. Whether you’re trying to match a specific page path, query parameters, or a combination of dynamic URL elements, regex can help you capture those interactions with precision. By understanding and applying regex correctly, you can create highly customized triggers that enhance your tracking and analytics setup in GTM.<\/p>\n","protected":false},"excerpt":{"rendered":"
