Retrieval Layer Intelligence Report
Monthly benchmarks and strategic guidance for navigating the shift from Search Engines to Action Engines.
Updated February 10, 2026
We have merged these reports to provide a unified view of how Interfaces (the browsers where users ask) impact Outcomes (the referral traffic your site receives). This permanent hub is updated monthly with proprietary data and strategic guidance for modern SEO/GEO.
The Market Split: Volume vs. Intent
The retrieval layer has moved beyond a simple popularity contest. A direct pull from our Similarweb integration confirms a Tier 1 Statistical Delta:
- Google Gemini Surges: Now capturing 33.1% of the referral basket, a +11.6 percentage point increase representing explosive growth in AI-driven referral traffic.
- ChatGPT Holds Strong: While experiencing modest share erosion to 62.9% (-1.6 points), it remains the dominant referral source, though its near-monopoly has clearly evolved into a two-player race for scale.
- The Counter-Narrative: Anthropic's Claude now holds the lowest bounce rate in the cohort (26.7%), signaling the stickiest, highest-intent user base—a dramatic shift from Perplexity's previous position, as engagement quality becomes the new competitive frontier.
The Infrastructure Shift: From "Search" to "Action"
This data is critical as the market pivots toward agentic action. The emergence of Google's Universal Commerce Protocol (UCP) is a definitive Tier 2 Infrastructure signal:
- Bypassing the Click: UCP allows agents like Gemini to bypass traditional website front-ends to execute purchases via a standardized API layer.
- Transactional Authority: The game is shifting from a battle for "clicks" to a battle for "transactional authority".
- Agent-Ready Brands: While agentic browsers haven't materialized as standalone traffic sources yet, the plumbing is being built to favor brands that are "agent-ready" for direct commercial outcomes.

AEO: Adopt a Bifurcated Strategy
The data mandates a two-pronged approach. Optimize for broad, informational queries on ChatGPT/Gemini to capture top-of-funnel awareness—these platforms now command 96% of AI referral traffic. Simultaneously, target long-tail, high-intent keywords for Claude and Perplexity, where the significantly lower bounce rates (26.7% and 32.2% respectively) indicate higher-quality engagement and a greater probability of conversion.
GEO: Prioritize API-First Commerce
Google's UCP is a clear signal that Agentic Readiness is the next competitive frontier. We must advise e-commerce clients to move beyond front-end website optimization and invest in a robust, API-first architecture for their product catalogs and checkout processes. The goal is to ensure their products are not just discoverable but directly transactable by an AI agent, bypassing the traditional site visit entirely. With Gemini's explosive growth (+676.8% in visits, +11.6 points in referral share), this is no longer a future consideration—it's an immediate strategic imperative.
Modern SEO: Architect for "Agentic Ingestion"
High-value users are congregating on quality-focused platforms like Claude (lowest bounce rate at 26.7%) and Perplexity. Our Modern SEO approach focuses on perfectly structured, factual data (Schema, clean product feeds, and technical documentation). This ensures your brand is flawlessly represented and trusted by the models that the most valuable AI-driven audiences use. While these platforms represent smaller referral volumes (2.3% and 1.6% respectively), their superior engagement metrics signal higher commercial intent and conversion potential.
