The Impact of Generative AI on Website Traffic and Conversion Rates

In an era increasingly dominated by digital channels, PLAN-B Marketing Partners, based in Shinagawa, Tokyo, has released a crucial report analyzing the influx of website traffic driven by generative AI technologies such as ChatGPT. This report offers a comprehensive look at how generative AI is shaping online marketing dynamics, particularly focusing on traffic sources and conversion rates.

Background of the Study

As generative AI technologies emerge, there's a growing interest in how these new tools influence web traffic. However, questions linger regarding the actual increase in traffic from these sources and the validity of the common belief that traffic generated through AI leads to higher conversion rates (CVR). PLAN-B's investigation aims to provide clarity on these issues.

The study carefully analyzed web sessions originating from generative AI as a traffic source. To achieve this, a variety of websites that hadn’t adopted generative AI strategies were scrutinized, with particular attention to session counts and the corresponding conversion trends.

Study Overview

• - Study Title: Analysis of Generative AI Traffic and CVR
• - Duration: February 1, 2025, to April 30, 2025
• - Subjects: A random selection of multiple client websites
• - Methodology: Data was extracted from GA4, specifically looking at session counts segmented by referral sources.

Key Findings

Increase in Sessions

The comparative analysis of website traffic between February and April 2025 revealed that 83.0% of the studied sites noted a rise in sessions attributed to generative AI. Notably, one site experienced a staggering growth of 605.6%, underscoring a trend where session increases occur without specific targeting strategies focused on AI.

Despite this impressive growth in session numbers, they still contribute minimally to overall traffic—typically less than 1%. These statistics indicate that while generative AI is a burgeoning traffic driver, its impact remains relatively mild compared to traditional channels.

Conversion Rates Analysis

When evaluating conversion rates, only 35.1% of websites experienced higher CVR from generative AI traffic compared to other sources. This statistic contrasts with the prevailing notion that AI-driven sessions incur significantly better conversion outcomes. The reality reflects a diverse landscape, with differing successes across sites, highlighting that merely attracting traffic via AI does not guarantee conversions.

The report suggests possible reasons for the limited CVR from AI traffic, including:

• - A predominance of visits triggered by generic information-seeking behavior.
• - Insufficient alignment between AI-generated conversation contexts and the landing pages users are directed to.

Summary and Implications

The research clearly indicates a positive trajectory in traffic from generative AI, with 83.0% of the sites analyzed showing growth during the study period. This upward trend persists despite a lack of targeted strategies tailored for generative AI.

However, the assumption that increased AI traffic translates directly into higher conversion rates is challenged by the findings. Businesses must approach generative AI traffic holistically; capturing this traffic is only one part of the equation—the true challenge lies in converting this interest into tangible business outcomes.

As generative AI technologies advance, employing robust strategies—like optimizing content and refining landing pages tailored to AI interactions—will become crucial. Companies should carefully analyze their own data to tailor their approach, aiming to not only increase traffic but also enhance the quality of leads acquired through these channels. By doing so, they can create effective and strategic marketing initiatives that leverage the strengths of generative AI.

This report shines a light on the necessity for businesses to remain astute in understanding user behavior and needs driven by AI, fostering a deeper strategy development rooted in data-driven insights.
