The Agent-First Web and the Rise of NLWeb: Optimising for the Future of AI Interfaces
By Rishan Chopra
The internet is undergoing a foundational transformation. With the emergence of Microsoft’s NLWeb, we are entering the age of the agent-first web — where AI agents become the dominant interface between users and the digital world.
What is NLWeb?
NLWeb is an open-source initiative that empowers websites to communicate in natural language through conversational interfaces. It builds on widely adopted formats like Schema.org and RSS, integrating them with the capabilities of large language models (LLMs).
NLWeb Enables:
- Natural language querying of site content\
- AI-native interfaces layered onto websites\
- Machine-readable presentation of services and products\
Analogy: NLWeb is to AI agents what HTML was to web browsers — a protocol for discovery, interaction, and representation.
Why the Agent-First Web Matters
Traditionally, SEO meant optimising content for search engines and blue link rankings. But AI agents—like Google’s SGE, ChatGPT, and Microsoft Copilot—don’t just return links. They summarise, recommend, and act.
In this world, metadata becomes:
- *Visible and actionable*
- *A primary determinant of brand representation*
- *The interface through which decisions are made on your behalf*
Insight: In the agent-first web, traffic is routed via decisions made by AI—not by users clicking links. That means optimising for agents is now a strategic imperative.
The Rise of Agent Experience Optimisation (AXO)
At Adgent, we believe the next wave of digital strategy is AXO — Agent Experience Optimisation.
AXO Requires:
- Enriching metadata across all digital assets\
- Structuring product and service data for discoverability\
- Monitoring how AI agents summarise, interpret, and relay brand information\
AXO is to agents what SEO was to search.
Practical Steps for Brands
To prepare for this paradigm shift, brands should begin optimising now:
- Audit Metadata: Ensure your product/service pages use up-to-date Schema.org markup.\
- Deploy NLWeb Protocols: Start experimenting with NLWeb templates for key pages.\
- Structure Content for Agents: Focus on clarity, hierarchy, and semantic richness.\
- Monitor Agent Representations: Use tools to track how your brand appears in AI summaries.\
- Iterate on Agent Feedback: Treat agent responses like you would SEO performance data.
FAQs on the Agent-First Web & NLWeb
*Q: What is the agent-first web?* It refers to a digital environment where AI agents—not human users—are the primary interface for discovering and interacting with online content.
*Q: What role does NLWeb play?* NLWeb provides an open-source framework that makes web content accessible, readable, and actionable by AI agents.
*Q: How is this different from traditional SEO?* Where SEO focuses on human-visible search rankings, AXO focuses on machine-interpreted metadata that guides how agents summarise and recommend content.
*Q: Is this technology ready for adoption?* Yes. NLWeb is live and evolving. Early adopters will benefit from experimentation, learning, and leadership.
Final Thought: Metadata Is the New Message
The agent layer is becoming the new digital battleground. In this world:
- *Agents are the interface*
- *Metadata is the message*
- *AXO is the strategy*
Brands that adapt early to this shift will not only maintain relevance but gain strategic edge. The future isn’t just about being found — it’s about being represented accurately and advantageously by AI.
