Your persona is probably sitting in a folder somewhere, aging slowly and covered in cobwebs, waiting for someone to update it. Well, it’s time to bring it back out.
AI Search systems now increase their trust in a user the more they know about them. Preferences, location, browsing habits, and the persona a user projects all shape what the AI recommends. Thanks to AI models, personalization is everywhere these days but especially in search and digital marketing.
Let’s talk about how AI interprets and creates personas for the new age.
Age, income, and job title are the fossil record of persona work. AI personalization goes beyond keyword matching by using Natural Language Processing (NLP) to understand the specific context, history, and transactional intents of a user.
AI can pull customer data from various sources, including social media interactions and previous website visits, analyzing that data to better understand behavior patterns and context. What that means practically: a user’s persona is being reconstructed from the trail they leave, not from anything they explicitly tell the system.
Every interaction leaves a signal. Stanford research on AI recommendation systems confirms this shift, showing that these systems should “go beyond item-level prediction and adopt a higher-order understanding of users.” This starts with a specific prediction of a user’s real-time intent when visiting a platform, whether that’s a desire for novelty or familiarity. Stanford found that incorporating that intent prediction into YouTube’s recommendation engine led to a 0.05% increase in daily active users.
In multi-turn search, context compounds and each turn builds on the last. While traditional search relied on short, disconnected queries, generative platforms invite follow-ups, with each new turn deepening the session’s understanding of a user’s intent. According to data from Profound, we found that the average ChatGPT conversation runs 5.2 turns. That’s 5.2 chances for the system to sharpen its read on who it’s talking to.
This has direct implications for how you think about personas. Personas for SEO have always been how we attempt to define user intent, but some are created only through the lens of a specific product, limiting our understanding of the people behind the queries.
Here’s where things can get a little uncomfortable.
At Google I/O 2025, Google announced personal context in AI Mode to transform the search experience from a universal approach into a hyper-personalized assistant. Unlike ChatGPT’s conversation memory, Google Personal Intelligence integrates your entire Google ecosystem (Gmail, Calendar, Drive, search history, and location data) to deliver results uniquely tailored to your individual context and preferences.
This is a shift in what search means. A user looking for “project management tools” isn’t just getting generic results anymore. They’re getting results informed by the documents in their Drive, the emails in their inbox, and the calendar events on their schedule. The system knows what kind of project manager they are before they finish typing the query.
ChatGPT has moved in the same direction. Memory in ChatGPT works in two ways: saved memories the user has explicitly asked it to remember and chat history insights that ChatGPT gathers from past conversations to improve future ones. By mid-2025, every major AI vendor — OpenAI, Anthropic, Google, Microsoft — had announced or shipped persistent memory.
Microsoft Copilot uses context retention across Microsoft 365 products, tracking task state, user instructions, and cross-application memory including documents, chats, and email context. Google DeepMind’s Gemini models integrate memory across products like NotebookLM. This has become the mechanism through which AI builds a picture of who a user is and what they care about.
Your personas now need to account for connected data. A B2B buyer who uses Google Workspace is not being seen by AI the same way as someone who doesn’t. The signals flowing from their calendar, email threads, and Drive activity are all shaping what they see.
So, what do you actually do with this?
The shift is from demographic profiles to intent signatures, which are clusters of behavior that reveal what a person is trying to accomplish across tools, conversations, and searches over time. Personalization is evolving from general experiences based on demographics to highly individual interactions based on unique search intent, preferences, and context. Your personas need to reflect that evolution.
As AI search becomes more personalized, personas should layer in real-world data (like location, industry trends, or other environmental factors) to reflect the actual people behind the queries. This richer context makes content more relevant and increases the chances that AI will surface it when an audience is searching.
Concretely, an intent signature for a persona should include:
Personalization doesn’t simply adapt answers to users but rather rewrites their information environment. A persona that’s built around static demographics will map poorly to that environment. One built around intent signatures, behavioral clusters, and ecosystem context will map well.
Next, we’ll look at the tools and workflows that can help you develop personas and how they’ve evolved over the years to meet the challenges of the AI era.
