Section 1
Why the pre-briefed visitor is different
The AI-briefed visitor differs from the traditional cold visitor in consequential ways. They arrive informed, they already understand the category basics the AI explained, so content that re-explains the basics wastes their time and signals you're not meeting them where they are. They arrive with expectations the AI set, about what your kind of service involves, what good looks like, possibly about you specifically, and your site is now measured against those expectations. They arrive having compared, the AI may have positioned you against alternatives, so they land already weighing you versus others. And they arrive at a different stage, often further along, closer to deciding, because the AI did the early-stage educating. So the pre-briefed visitor needs less introduction and more confirmation, differentiation, and decision support, a different job than introducing a cold visitor to your category. The principle: the AI-briefed visitor arrives informed, with expectations and comparisons, further along, needing confirmation and decision support, not basic introduction. (This applies the AI-search and conversion research cited across this library.) The visitor who asked an AI about you before arriving isn't starting from zero, they're starting from whatever the machine told them. They know the basics, they have expectations, they've been compared to your rivals, and they're closer to deciding. A website that greets them like a stranger who's never heard of your category is answering a question they already asked someone else.

How to design the AI front door
1, Confirm and build on what they likely know. Assume a meaningful share arrive informed about the basics, and design to confirm and build on that, quickly establishing you fit what they learned, then advancing them, rather than re-explaining the category from scratch. 2, Meet (and beat) the AI-set expectations. They arrive measuring you against what the AI led them to expect. Make sure your site quickly confirms you meet those expectations, and ideally exceeds them, so the pre-briefed visitor's first impression validates rather than disappoints. 3, Win the comparison they've already started. Since the AI may have compared you to alternatives, your site should support the visitor in concluding that comparison in your favor, clear differentiation, evidence, the reasons you're the right choice for their need. 4, Support the decision, not just the introduction. Because they're often further along, prioritize decision-support content (proof, specifics, clear next step) over introductory content, meet them at the decision stage the AI advanced them to. 5, Stay consistent with what the AI says about you. The pre-briefed visitor will notice if your site contradicts what the AI told them. Keep your site consistent with your AI representation (which is partly why AI-legibility matters), so the hand-off from AI to your site is seamless, not jarring.
Section 3
Designing the AI front door, in one view
The takeaway: a growing share of visitors arrive pre-briefed by an AI, informed on the category basics, carrying expectations the AI set, having been compared to alternatives, and often closer to deciding. This AI-briefed visitor needs a different website job than the cold visitor: less introduction, more confirmation, differentiation, and decision support. Design the AI front door by confirming and building on what they likely know, meeting and beating the AI-set expectations, winning the comparison they've started, prioritizing decision support, and staying consistent with what the AI says about you. The visitor who consulted a machine before arriving isn't a blank slate, and the website that greets them as one is a step behind the conversation they've already been having. (The AI-front-door framing synthesizes the AI-search research established across this library.)

Execute This With AI
Step 1, Inputs. Note what an AI likely tells buyers about your category and you, and how your site currently opens (introduction vs. decision support). Step 2, Run the prompt: You are a strategist on the "AI front door", designing for visitors who arrive PRE-BRIEFED by an AI: informed on basics, carrying AI-set expectations, already compared to alternatives, often closer to deciding. They need confirmation, differentiation, and decision support, not basic introduction. Stay consistent with what AI says about me. What AI likely tells buyers about my category + me: [DESCRIBE]. How my site opens: [introduction-heavy / decision-support / mixed]. Do four things: 1. Assess whether my site is designed for a cold visitor or an AI-briefed one. 2. Recommend how to confirm/build on what they know instead of re-explaining basics. 3. Help me meet AI-set expectations and win the comparison they've started. 4. Tell me how to shift toward decision support and stay consistent with my AI representation. Meet the pre-briefed visitor where the machine left them. Step 3, The hand-off test. Ask an AI about your category and you, then visit your own site, "does my site continue that conversation smoothly, or does it restart from zero and contradict the AI?" Tools and expected output. Any frontier chat model (and the AI engines to see the briefing), plus your site. Expect a cold-vs-briefed assessment, confirm-and-build guidance, comparison/expectation help, and decision-support shifts. The QA discipline: actually ask an AI about your category and yourself to see the briefing your visitors arrive with, then check whether your site continues that conversation or restarts and contradicts it, the hand-off from AI to site should be seamless. The model designs the front door; the real AI briefing shows what it opens onto. A growing share of your visitors arrive pre-briefed by an AI, informed on the basics, carrying expectations the machine set, already compared to alternatives, and often closer to deciding. This AI-briefed visitor needs a different website job than the cold visitor: less introduction, more confirmation, differentiation, and decision support. Design the AI front door by confirming and building on what they know, meeting and beating the AI-set expectations, winning the comparison they've started, prioritizing decision support, and staying consistent with what the AI says about you. The visitor who consulted a machine before arriving has already started the conversation, and your website's job is to continue it well, not to greet them as a stranger who's never heard of you.
