Full Answer
The threshold exists because Google's machine learning models need a statistically significant sample of consented behaviour to infer what non-consenting visitors would have done. Below 1,000 denied-consent events per day, the model doesn't have enough signal to extrapolate reliably, so Google simply doesn't activate it. Most small and mid-sized WooCommerce stores sit well under that line.
Here's the thing... the maths compounds against you. If your store gets 500 daily visitors in an EU market and 60 percent accept cookies, that leaves 200 denied events per day — one-fifth of the threshold. Even stores with 2,000 daily visitors and a 70 percent acceptance rate produce only 600 denied events, still short. The gap between your store's traffic volume and Google's modelling floor determines how much conversion data you permanently lose.
Google Ads has its own separate threshold for conversion modeling — approximately 700 ad clicks per day for seven days. Most WooCommerce advertisers spending under $5,000 per month don't come close. The result is that both your analytics and your ad platform report only the consented subset, making [your CMP the single point of failure](https://seresa.io/blog/privacy-compliance/google-made-your-cmp-the-single-point-of-failure-for-woocommerce-conversions) for measurement accuracy. Server-side first-party tracking captures events regardless of consent-mode state, giving you a complete picture without depending on modelling thresholds you'll never reach.
