Google has rolled out major improvements to incrementality testing, making it easier for advertisers to measure the true, causal impact of their campaigns.
Key updates include:
- Lower spend thresholds: experiments that once required $100K can now be run for as little as $5K, opening access to smaller advertisers.
- Improved accuracy: refined statistical models now deliver 50% more conclusive results, offering clearer insights.
- Faster reporting: advertisers can set custom test sizes and confidence levels, accessing results directly in the UI for quicker decision-making.
Together with Attribution and Marketing Mix Models (MMMs), these improvements give marketers a more complete, data-driven view of performance and ROI.
