France Experiences Significant Click-Through Rate Decline Following AI Overview Launch

Paris, France – July 22, 2026 – France became the latest major search market to experience the impact of Google’s AI Overviews, with data revealing a substantial decrease in click-through rates (CTR) for many French websites within days of the feature’s rollout. This analysis, conducted by Ahrefs, provides a unique opportunity to observe the immediate before-and-after effects of AI Overviews in a controlled environment, as the launch date was clearly defined, unlike previous market introductions that were often intertwined with broader algorithm updates.

Researchers tracked 963 domains in Google Search Console for 28 days prior to the July 22, 2026, launch and for nine days following its implementation. Xibeijia Guan, Ahrefs’ data scientist, analyzed the data for French sites, concluding that Google’s AI Overviews are already significantly impacting organic traffic. The findings indicate that domains most exposed to AI Overviews saw their click-through rates plummet by over a fifth in just nine days, while those with minimal exposure experienced negligible changes. This stark contrast strongly suggests that the observed decline is directly attributable to AI Overviews, rather than a general algorithm update.

The study revealed an overall CTR drop of 3.4% across all domains analyzed in France over the nine-day post-launch period. However, for domains with high exposure to AI Overviews, the CTR decline was a staggering 23.1%, approximately six times greater than the overall average. This significant impact is not confined to a small number of sites; 82.2% of highly exposed domains experienced a loss in CTR, indicating that avoiding the negative effects of AI Overviews has become the exception rather than the rule at high levels of exposure.

A detailed analysis of the relationship between AI Overview exposure and CTR decline suggests a linear correlation. For every additional percentage point of AI Overview exposure across the studied domains, there was a corresponding loss of approximately one percentage point in click-through rate. This provides a quantifiable metric for website owners to estimate potential traffic losses: if 15% of a website’s queries trigger an AI Overview, it can anticipate a roughly 15% reduction in its CTR. While this is a simplified model, it offers actionable insights for businesses to assess their risk by evaluating their AI Overview exposure rate.

The data further illustrates a pattern of increased impressions coupled with decreased clicks. While the visibility of pages on Google Search results pages (SERPs) generally remained stable, and in some cases even increased, the number of clicks received significantly diminished. This phenomenon, consistent with previous Ahrefs research on AI Overviews globally and the broader trend of "the great decoupling," indicates that AI Overviews do not necessarily remove content from search results but rather make it redundant within the SERP. One extreme case observed involved a website experiencing a 183% increase in impressions alongside a 1.9% decrease in clicks, effectively reducing its CTR by more than three times.

Across the entire market, the median CTR decline was 5.7%, with a corresponding 8.8% drop in clicks. However, this median figure masks a more severe distribution of losses. Nearly half of the analyzed websites experienced a decline of over 10% in their daily clicks, and one in twenty saw their clicks halved within the nine-day period. The study also highlights that AI Overview exposure is likely to increase, with the median AI Overview rate among the studied domains currently at 5.4%, and 29% already exceeding 10%. These figures have consistently trended upwards in all markets where AI Overviews have been implemented. Notably, French (.fr) domains in the panel experienced a median click loss of 12.3%, indicating they are more exposed than international competitors operating within the same market.

The health sector emerged as the most severely affected, with an AI Overview rate of 22.2%, the highest observed in the study. This sector also experienced a significant CTR drop of 20.4%. The nature of health-related queries, often informational with concise answers that fit well within AI Overviews, makes them particularly susceptible. The study emphasizes that the intent behind a query is a more critical determinant of impact than the industry vertical. Queries that can be answered with a single paragraph are at high risk of being absorbed by AI Overviews, whereas those requiring tools, accounts, pricing, purchases, or nuanced human opinions tend to fare better.

The long-term impact of AI Overviews is projected to worsen, mirroring trends observed in other markets. Global research by Ahrefs indicated a progression from a 34.5% decline in position 1 CTR in spring 2025 to 58% by the end of 2025. This suggests that the negative effect does not diminish over time but rather intensifies as AI Overviews become more prevalent and users adapt to receiving information directly from the AI.

The methodology for calculating the CTR decline involved analyzing raw observed changes. The 23.1% median CTR figure for highly exposed sites represents the direct drop. When accounting for a 2.3% CTR increase observed in the control group during the same period, the adjusted impact of AI Overviews on highly exposed sites is estimated to be a 24.8% decrease.

In conclusion, the arrival of AI Overviews in France has demonstrably reduced click-through rates for many websites, with the most exposed domains suffering significant traffic losses. The risk is quantifiable, allowing website owners to assess their exposure using tools like the SERP features filter in Site Explorer. The study reinforces the importance of focusing on click-through rate rather than impressions, as the latter has remained largely unaffected. The observed magnitudes of these declines align with findings from other research firms, suggesting a widespread trend of decreasing organic CTRs. The data indicates that the French market is now part of a broader shift towards "zero-click" searches.
