Google's A2A Push: When AI Agents Start Working Together, What Does the Enterprise Website Become?
The most important job of an enterprise website used to be making people understand who you are, what you sell, and why they should reach out.
Now, it must serve another kind of visitor: not a person browsing the page, but an AI agent arriving with a task.
That agent might be screening suppliers on behalf of a user, checking whether a product supports a specific deployment model, looking for case studies, requesting documentation, or deciding whether the matter should be escalated to a human. It won't linger on your homepage for three minutes like a person would. What it cares about is: does your website have clear, credible, and verifiable answers?
In April 2025, Google released the open Agent2Agent (A2A) protocol. The goal isn't to build "another chatbot"—it's to let agents built by different vendors on different frameworks discover each other, exchange information, and coordinate tasks. In June, A2A moved under open governance at the Linux Foundation.
What enterprises should really pay attention to isn't another protocol name entering the scene—it's that "who is looking for you on behalf of your customers" is changing.
Figure 1: A2A doesn't point to a single all-purpose agent, but to a group of specialized agents that divide and coordinate work.
Let's Be Clear: A2A Isn't About Letting Agents Place Orders on Your Behalf
A2A stands for Agent2Agent. In simple terms, it provides a common language for collaboration between agents.
In Google's design, a "client agent" can propose a task, and a "remote agent" handles execution or returns results. The two sides can perform capability discovery, message exchange, task status synchronization, and deliver task artifacts. Long-running tasks don't need to wait until completion—agents can continuously update status. Google's announcement also notes that capabilities can be publicly declared through a JSON-format Agent Card.
This matters because enterprises won't have just one agent: sales, customer support, knowledge base, procurement, compliance, and data analytics may each have their own specialized agents, each connected to different systems.
The common challenge has been: every agent is like an island. It can get things done, but it struggles to work with other agents.
A2A's goal is to build bridges between these islands.
A2A doesn't make agents smarter; it tries to make existing agents collaborate with each other more reliably.
So What's the Relationship Between A2A and MCP?
Putting them in a "who replaces whom" framework is basically asking the wrong question.
| Dimension | MCP | A2A |
|---|---|---|
| Primary problem it solves | How agents connect to tools, data, and context | How agents discover and collaborate with other agents |
| Typical relationship | One agent calls a tool or data source | One agent delegates to or coordinates with another agent |
| Focus | Tool integration, context retrieval | Capability discovery, task lifecycle, messages, and artifacts |
| Meaning for enterprises | Lets agents do more things | Lets specialized agents across different systems connect the dots |
Google also describes A2A as complementary to MCP, not a replacement. The official A2A documentation emphasizes secure communication and interoperability between independent agents.
Figure 2: MCP is more of a connection layer from agent to tool, while A2A targets the collaboration layer from agent to agent. Both can coexist.
When Agents
When you begin collaborating, the role of the official website will shift three times first.
Before anything else, don't rush to think of the official website as "an API store that Agents can call." Most companies are still far from that stage, and there's no need to force it just to chase the trend.
But the role of the official website will indeed undergo three layers of change.
1. From a brand window to a verifiable repository of business facts
In the past, a homepage that said "industry-leading" or "serving countless clients" might have influenced people through atmosphere.
Agents don't buy that. They'll keep asking: What scenarios are supported? What are the limitations? Are the customer cases specific? Where are the pricing or delivery boundaries? Is the information up to date?
Vague marketing language won't disappear, but it will no longer be sufficient.
Product capabilities, applicable and non-applicable scenarios, delivery processes, integration methods, case evidence, responsible contacts, and contact paths—all of these will become more important public assets. The official website isn't just about looking polished; it's about making key facts findable, version-traceable, and source-attributable.
2. From a traffic endpoint to a trusted handoff point in workflows
A procurement Agent discovering you doesn't mean it can sign contracts on the client's behalf.
The more realistic path is: it first completes screening, gathers materials, and assesses fit; then it passes a structurally complete task to sales, consultants, or the client's internal Agent. Here, the official website serves as a trusted handoff, not an uncontrolled automated sale.
So "Contact Us" shouldn't just be a vague form. It should let people or systems with different intents know what the next step is: booking a demo, requesting a proposal, downloading technical materials, submitting requirements, or finding a human for confirmation—each with its own path.
3. From a collection of pages for humans to a single knowledge foundation for both humans and machines
This doesn't mean building two separate official websites.
The truly mature approach is: use one maintained set of business facts to generate human-facing product pages, case pages, FAQs, documentation, and landing pages; while also enabling systems to clearly describe capabilities, limitations, identity, authorization, and service boundaries.
What humans read is a credible narrative; what Agents read is decidable facts. The underlying foundation should be as consistent as possible.
Figure 3: External web pages and machine-readable capability declarations can originate from the same continuously maintained business knowledge.
What Agent Card reminds the official website: Don't hide the most important information
A2A's Agent Card describes what an Agent can do, along with its connection and security requirements. It doesn't mean "just adding a JSON file to the website and you're done." But it raises a very practical question:
If a partner, customer, or Agent wants to understand your capabilities in one minute, can they find an accurate, complete, and non-overpromising description?
This is exactly where many corporate websites expose their problems:
- Product pages only talk about concepts, not capability scope.
- Case studies only show logos, not the problem, process, and results.
- Documentation lags behind the product, with outdated screenshots and old promises lingering.
- Contact entry points don't segment traffic; all leads get funneled into one form.
- The website, sales scripts, and knowledge base each tell a different story.
In an Agent collaboration environment, these aren't minor "copywriting issues"—they're incomplete trust data. When facts contradict each other, automated workflows stall at the exact point where judgment is needed, and you're back to patching holes manually.
A minimum Agent-ready checklist for corporate websites
| Website Area | Role for Humans | Value for Agents | What to Do Now |
|---|---|---|---|
| Homepage | Quickly understand positioning and value | Determine whether you fall within the candidate scope | Use one clear positioning statement and link to specific capability pages |
| Product / Service Pages | Explain solutions and experience | Access capabilities, limitations, and applicable conditions | Clearly state inputs, outputs, boundaries, and delivery methods |
| Case Study Pages | Build trust | Verify industry, scale, results, and evidence | Replace the logo wall with a "problem–approach–result" structure |
| FAQ / Documentation | Address doubts | Quickly extract citable answers | Maintain searchable fact entries with update timestamps |
| Contact & Conversion Pages | Get people to take the next step | Trigger the appropriate downstream workflow | Segment by inquiry, demo, purchase, and partnership, and state response expectations |
Figure 4: The official website of the future still serves people—it just also becomes a trusted entry point for business facts and next actions.
It's not enough to "adopt A2A"—what enterprises really need to fill in is boundaries
The enterprise value of A2A isn't just in connectivity. It's in whether you can still maintain control after connecting.
The official enterprise documentation makes this clear: production communication should use HTTPS; authentication can rely on standard web mechanisms like OAuth 2.0 and OpenID Connect, with authentication requirements described in the Agent Card; task chains should also be integrated with tracing, logging, metrics, and audit. The A2A enterprise readiness documentation states this directly.
In other words, the protocol provides the "traffic rules" for collaboration, but the enterprise still has to define who gets on board, where they can go, what they can take away, and how issues can be traced after the fact.
Especially when it comes to pricing, customer data, orders, contracts, payments, and internal knowledge bases, both the official website and the Agent system need to make four things clear:
- Identity: Who is making the request, and which user or organization do they represent?
- Permissions: What can it read, write, or invoke?
- Approval: Which actions require human confirmation, and where are confirmation records kept?
- Audit: Which Agents did a task pass through, what data was it based on, and what was ultimately done?
This is also why "letting Agents collaborate freely" sounds cool, but what can actually enter an enterprise must be collaboration with permissions, boundaries, and records.
Figure 5: Viable Agent collaboration isn't about opening up permissions—it's about keeping every delegation, status change, and result delivery on a governable path.
What can the website team do now? Start with a 30-day foundational project
Don't treat A2A as some SEO plugin that "immediately boosts rankings." There's currently no evidence that merely supporting A2A earns search ranking bonuses.
The more realistic change it brings is this: when humans, search engines, AI answer systems, and business Agents are all looking for the same corporate facts, content quality, structure, and update mechanisms become more valuable.
Week 1: Inventory "what customers actually ask"
Pull together a table of the questions sales, support, delivery, and procurement answer most often. Prioritize the ones that affect deal outcomes and get asked repeatedly: who it's for, who it's not for, how pricing works, how integration works, how long rollout takes, how data is handled, and who owns support.
These questions shouldn't just live in employees' heads.
Week 2: Establish a single source of truth on the website
Define clear ownership for maintaining products, services, cases, credentials, pricing ranges, policies, and contacts. Add dates where dates can be added, state limitations where limitations exist, and don't pretend to be certain when you're not.
Clear boundaries don't lower conversion. They filter out wrong leads and strengthen trust with the right ones.
Week 3: Redo the "next step" on key pages
Let product pages naturally lead to technical documentation, case studies, FAQs, and consultations; segment the contact page by intent; route high-value actions into human review instead of making every visitor fill out a long form first.
There should be a short, clear, traceable path between what's shown externally and the downstream business process.
Week 4: Review with growth metrics, not page counts
Look at which issues bring high-intent visits, which cases are viewed repeatedly, which FAQs drive people into consultations, and which pages fail to answer what visitors are actually asking. Then update content, add evidence, and improve conversion actions.
This is exactly the turning point where a corporate website evolves from a "project deliverable" into a "long-term customer acquisition asset."
What We0 AI Can Handle Goes Beyond Just Building the Page
For most teams, the hard part has never been putting together a homepage.
The hard part is keeping brand messaging, product capabilities, case evidence, content updates, SEO/GEO, data monitoring, and lead generation on one continuous growth loop. A website must first be a reliable business system before it can qualify as a reliable entry point in the Agent era.
We0 AI is better suited for this: it connects Build -> Showcase -> Grow -> Leads around display-focused websites. It's not just about generating a page that looks good—it's about turning your website into an asset that can go live, be operated, be continuously optimized, and capture traffic from both search and AI recommendations.
When you start preparing your website for both people and Agents at the same time, what you need first isn't flashy features—it's clearer messaging, more verifiable content, and smoother conversion paths.
A2A is still evolving, and corporate websites don't need to become Agent platforms overnight. Getting it to the point of being a credible, maintainable, growth-ready business entry point already puts you a step ahead.
Frequently Asked Questions
What is the Google A2A protocol?
A2A stands for Agent2Agent, an open protocol released by Google in April 2025. Its goal is to enable capability discovery, task collaboration, and secure information exchange among AI Agents built on different frameworks, vendors, and platforms. The project later moved under the governance of the Linux Foundation. See the Google announcement and the Linux Foundation release for details.
What's the difference between A2A and MCP?
MCP primarily helps Agents connect to tools, data, and context; A2A mainly addresses discovery and collaboration between independent Agents. They complement each other: an Agent can use tools via MCP, then delegate part of a task to another specialized Agent via A2A.
Does a corporate website have to support A2A directly?
Not necessarily. For the vast majority of companies, the first step isn't publishing an A2A service—it's getting accurate, well-structured, and continuously updated website content and business boundaries in place. Only when you have clear cross-system Agent collaboration scenarios should you evaluate capabilities like Agent Cards, authentication, authorization, auditing, and API management.
Will A2A improve my website's SEO rankings?
For now, A2A should not be treated as an SEO ranking factor. What's more worthwhile is improving product pages, case studies, FAQs, documentation, and conversion paths so that search users, AI answer systems, and business Agents can all access consistent, trustworthy information.
What's the most important capability of an Agent-ready website?
It's not about putting a chat window up first. More importantly: public information should be consistent and verifiable, capabilities and limitations clearly documented, contact and human handoff clearly defined, sensitive actions protected by authorization and approval, and key content kept continuously updated.

Summary
The significance of A2A isn't about having every company deploy a group of Agents talking to each other tomorrow.
What it truly pushes forward is a higher standard: companies must enable external systems to understand them more accurately, and they must define collaboration boundaries more clearly.
The corporate website of the future isn't going away. It will gradually evolve from a static showcase page into a trusted business entry point shared by people, search, AI answer systems, and business Agents alike.
