Google has announced an update to the attribution models in Google Analytics 4 (GA4) to improve the accuracy of paid search campaigns.

Google plans to roll out adjustments over the next two weeks to address a longstanding issue where conversions originating from paid search were mistakenly attributed to organic search traffic.

According to the company’s statement, this misattribution occurs with single-page applications when the “gclid” parameter — a unique identifier for paid search clicks — fails to persist across multiple page views.

As a result, conversions that should have been credited to paid search campaigns were incorrectly assigned to organic search channels.

Improved Conversion Attribution Methodology

To address this problem, Google is modifying how it attributes conversions to ensure campaign information is captured from the initial event on each page.

Under the new methodology, the attribution will be updated to reflect the appropriate traffic source if a user exits the site and returns through a different channel.

This change is expected to increase the number of conversions attributed to paid search campaigns, potentially impacting advertising expenditures for marketers leveraging Google Ads.

Preparation & Review Recommended

In light of the impending update, Google strongly advises advertisers to review their budget caps and make necessary adjustments before the changes take effect.

As more conversions may be assigned to paid search efforts, campaign spending levels could be affected.

Proactive budget management should be used to align with evolving performance data.
