Marketing Attribution WordPress Guide: How to Track UTMs and Custom Events

Marketing Attribution WordPress Essentials

Marketing attribution in WordPress is crucial for any team running campaigns. Whether you’re using paid ads, email marketing, or organic content, you need to know which traffic sources lead to conversions.

Without clear attribution, marketing spend is based on guesswork. Fortunately, using UTM parameters and custom events allows marketers to track and connect the dots between visits and conversions—even across pages and sessions. In this guide, we’ll walk through how to implement a full marketing attribution WordPress setup using tags, JavaScript, cookies, and smart automation platforms like Sitebox.

What Is Marketing Attribution in WordPress?

Marketing attribution is the process of identifying which marketing action—ad click, newsletter, social post—caused a user to convert. In WordPress, this means tagging your URLs, storing those tags, and connecting them to user actions like form submissions or purchases.

Without attribution tracking, it’s impossible to know what’s actually driving results.

Why Use UTM Parameters for Attribution?

UTM (Urchin Tracking Module) parameters are query strings added to URLs that help track the source and purpose of each visit.

Common UTM Parameters:

• utm_source: Facebook, Google, LinkedIn, etc.
• utm_medium: CPC, email, social, etc.
• utm_campaign: Name of the campaign (e.g., summer_sale)
• utm_term: Keyword (optional)
• utm_content: Ad version or link variation

Example URL:

https://yourwebsite.com/?utm_source=google&utm_medium=cpc&utm_campaign=launch2025

Custom Events for Deeper Attribution

Custom events go beyond pageviews to measure interactions like:

• Button clicks
• Form submissions
• File downloads
• Video views

In WordPress, you can trigger these events using JavaScript and send them to analytics tools (like GA4, Meta Pixel) for deeper marketing attribution insights.

Store UTM Parameters Using JavaScript

To keep UTM values beyond the landing page, store them in localStorage or cookies:

function storeUTMs() {
  const params = new URLSearchParams(window.location.search);
  ['utm_source', 'utm_medium', 'utm_campaign'].forEach(key => {
    const value = params.get(key);
    if (value) {
      localStorage.setItem(key, value);
    }
  });
}
storeUTMs();

You can also use cookies:

document.cookie = "utm_source=google; max-age=2592000; path=/";

Pre-fill Hidden Form Fields in WordPress

Add this hidden input to your form plugin (e.g., WPForms, Contact Form 7):

<input type="hidden" name="utm_source" id="utm_source">

Then use JavaScript to auto-fill the field:

document.getElementById('utm_source').value = localStorage.getItem('utm_source');

This ensures UTM data gets submitted with the form, allowing for lead attribution.

---

Send Custom Events for Attribution

Example: Send form submission data to Google Analytics 4:

gtag('event', 'form_submit', {
  campaign: localStorage.getItem('utm_campaign'),
  source: localStorage.getItem('utm_source'),
  event_category: 'lead',
  event_label: 'Contact Form'
});

You can do the same for Meta (Facebook) Pixel or LinkedIn Insight Tag.

Best Practices for Marketing Attribution in WordPress

✅ Always Use Hidden Fields
Capture UTMs in all lead forms.

✅ Respect Privacy Laws
Delay tracking until user consent (GDPR, CCPA).

✅ Set Cookie Lifespan Wisely
Typically 7–30 days to align with campaign goals.

✅ Test on All Browsers
LocalStorage and cookie behavior can vary.

✅ Use a Consent Management Platform (CMP)
To block scripts until consent is given.
