Should I Use utm_content to Test Different Versions of the Same Ad?
Yes, you should use the utm_content parameter to test different versions of the same ad. It is the correct way to measure which specific ad creative, like a different image or headline, is responsible for generating leads and booked jobs. Without it, all your ad variations get lumped together under a single campaign, making it impossible to know which creative actually works. This parameter allows you to run clean A/B tests in channels like Facebook or email, providing the data needed to optimize your ad spend and creative strategy. This article explains how to use the parameter and find the performance data in Google Analytics.
How to See A/B Test Results in Google Analytics
To see which ad version is winning, go to the Traffic Acquisition report in GA4. First, set the primary dimension to 'Session campaign' to isolate your campaign's overall performance. Next, add a secondary dimension by selecting 'Session manual ad content'. This action splits the campaign data, showing you separate rows for each utm_content tag you used. You can then see exactly how many sessions, conversions, and other key metrics each specific ad creative generated, giving you a clear winner.
How to Use utm_content for Ad Variations
The utm_content parameter acts as a label for differentiating links that point to the same place. When testing two Facebook ads in the same campaign, your main tags (utm_source, utm_medium, utm_campaign) will be identical. You simply add a unique utm_content tag to the end of each ad's destination URL. For example, use utm_content=ad-version-A for one and utm_content=ad-version-B for the other. This setup keeps your high-level campaign reporting clean while enabling you to compare the performance of specific ad creatives.
The ROI Insights Approach
ROI Insights provides the clarity needed to optimize your campaigns, ensuring you double down on the ad creatives that actually generate revenue.
More Uses for the utm_content Parameter
This parameter is also valuable for optimizing other marketing channels, like email newsletters. If your email includes a 'Book Now' button at the top and a text link at the bottom, you can tag them with utm_content=top-button and utm_content=bottom-link. This reveals which link placement your customers prefer to click. This insight is crucial for designing future email layouts that are more effective at driving conversions and booking more jobs for your business.
Key Takeaway
Use the utm_content parameter to tag different ad images or button placements within the same campaign, allowing you to see exactly which creative drives leads.
