The Problem

Attribution Breaks Across Pages

You're running high-value campaigns and landing users on Eloqua pages — but when the journey involves more than one page, your UTM parameters vanish. That means your CRM records are missing critical data about campaign source, medium, or keyword.

hen users land on an Eloqua landing page through a tracked campaign link (with UTM parameters), everything starts off great. But the second they navigate to another page — like a form or content download — the UTM data disappears. This leads to:

• Incomplete lead attribution
• CRM syncs with blank campaign data
• Frustrated marketing teams with no visibility into what actually worked

The Solution

LocalStorage Persistence

Instead of relying on the page URL every time, we capture UTM parameters once, then store them in the browser using localStorage. Later pages can retrieve and re-populate those values into hidden form fields before submission.

This means users can navigate freely — and you still capture your UTM campaign data.

We’ve created a single JavaScript block that you can add to all your Eloqua landing pages. This script:

• Captures UTM values from the URL
• Stores them in localStorage
• Automatically fills hidden form fields with the values
• Works even if the form is on a different page than the entry point

You don’t have to choose between capturing or repopulating — it does both.

How to do it

How to Persist UTMs with JavaScript

1. Capture and Store on Entry Page

Add this to the head or before your closing /body tag on every page where you want to persist or submit UTM values:

2. Auto-Fill Fields on Subsequent Pages

Make sure your Eloqua form has the following hidden fields (with matching id and name:

No values needed in these fields — the script fills them in dynamically.

Sprint Task Breakdown

Sprint Task: Add a single JavaScript block to every Eloqua page for UTM persistence and field population.

Subtasks:

• Add combined JavaScript to master landing page template
• Add UTM hidden fields to Eloqua forms
• QA test across entry and follow-up pages
• Confirm UTM data reaches Eloqua and CRM
