Google Buys Metaweb, the One Company That Could Revolutionize Google Search

Google just purchased Metaweb, a startup that indexes…well, "things," would be the best way to put it. This isn't just another acquisition: Metaweb could be the best thing to ever happen to Google Search.

Google Search · RESEARCH

Authentic. Relatable. Visual. Snackable

  • Trusts Google for accuracy. Found it lacks “vibes” and human connection
  • Feel SRP often buries human perspectives under SEO-optimized or commercial results. The “-reddit” effect.
  • Traditional blue links perceived as "high friction" and visually "unnappealing"
  • Prefer to steer discovery process rather than be passively led

PRODUCT PRINCIPLES

1.

Excel at broad queries

Broad queries represent both a core strength and opportunity

2.

Build confidence at the top of the page

Users should know whether SRP will fulfill their need by the end of the first viewport

3.

Morph radically on scroll

After answers, should be diverse, immersive, inspiring, and personal

4.

Ground users with results

Maintain and build upon the core strengths of classic blue links

5.

Enter the zeitgeist

Improve the taste and cultural relevance of content on SRP

Big Bets on SRP

AI MODE · GOOGLE SEARCH

A new surface
inside Search

Speed

AI Mode needed design velocity infeasible in the traditional SRP due to business and ecosystem constraints.

Revenue

Search drives the majority of Google's revenue. A separate surface contained the risk.

Research

UXR pointed to the same finding: people wanted Search to be Search. A new surface honored that.

AI Mode — cookbook recommendations

AI MODE · UX RESEARCH

Research revealed a gap

  • Overall satisfaction trailed competitors
  • Turn depth and query length were shallower than benchmarks
  • The model was too passive — users wanted it to lead the conversation
  • Refusals were the top driver of negative sentiment
  • The experience felt robotic, cold, and impersonal

How the team built signal

Loss Pattern
Analysis

  • Monitored quality signals after each model release to surface emerging loss patterns
  • Triaged regressions across dimensions like relevance, verbosity, and tone in post-training
  • Funneled findings back into base model improvements ahead of each major release

Aspirational
Research

  • Built two new research programs from scratch
  • A sentiment framework to quantify how the model's tone and voice landed with users
  • A competitive longitudinal user eval framework to benchmark against leading AI products over time

Design System

Insight over warmth

Research showed that attentiveness and insight drove higher satisfaction and helpfulness ratings than purely emotional traits like empathy or humor.

Competitors

  • Warmth & friendliness
  • Emotional expression
  • Humor & personality

Search AI

  • Insight & attentiveness
  • Collaborative depth
  • Situational awareness

Warm, reliable tone — striking the right balance between friendliness and over-familiarity

Four foundational traits

Reliable

Factual, credible, consistent. Puts truth and understanding first.

Optimistic

Positive and thoughtful. Assumes good intent, frames things constructively without being patronizing.

Collaborative

Proactive and engaging. Acts as a thought partner — moving the journey forward, not just answering the immediate question.

Useful

Tailored and insightful. Navigates complexity to offer deep understanding and actionable recommendations.

Collaborative

Open-minded · Authentic · Insightful · Straightforward

Situationally Aware

Empathy · Formality · Energy · Humor & Wit

"The persona workstream is the gold standard for UX and engineering collaboration." — Engineering VP

To be truly collaborative,

it needed to be

personal.

PERSONAL INTELLIGENCE · THE GAP

67%

of US users said their last Search felt "at least somewhat personalized."

2–3%

of organic content was actually technically personalized.

That gap is the entire story of Personal Intelligence.

AI OVERVIEWS · 2024

The high-water mark
of the answer paradigm

AI Overviews was Search's first AI-first experience — one of the largest growth drivers in Search history. For over a billion people, it was their first time using an AI product.

But user patterns told a different story: people were still asking keyword-driven, short queries. Answers had won the battle. The question was whether they'd win the war.

THE OPPORTUNITY

For the first time,

people could ask questions

the way they actually think.

MY TEAM'S SCOPE

A cross-Search effort

AI Mode was a CEO-level initiative — every Search team contributed. My org took on several 0→1 initiatives across two key areas:

Funnel

SRP → AI Mode entry points, reconciling disparate top-of-page experiences

Persona

Conversational design strategy, voice, model behavior training

Personal Intelligence

Cross-K&I personalization strategy, CEO presentation, launch

Agentic

Concept to Google I/O launch in 30 days

THE FUNNEL

Three experiences, one page

Visual Entities

Rich, visual results at the top of the page

AI Overviews

AI-generated answer in context

AI Mode

Full conversational surface

Reconciling these disparate top-of-page experiences — each with different design languages, interaction models, and business metrics — was a core challenge for my team.

MODEL BEHAVIOR

Building a discipline that didn't exist

Nobody on the team could answer a simple question: how does our work actually influence model training?

Three siloed disciplines — technical writers, content designers, UX writers — most still writing UI strings. To build AI persona at scale, we needed a unified team that could define and train voice into a model.

NEW ORG: CONTENT STRATEGY

Content Design + Conversation Design + Technical Writing → 30 people, one mission: define how Search speaks.

THE PROBLEM

People trusted Google on quality.
Not on collaboration.

Lower satisfaction vs. competitors on tone and warmth

Lower turn depth — people weren't coming back for follow-ups

Younger users rated the experience as cold and emotionally flat

PARTNERSHIP WITH PM + UXR

Two ways to define "quality"

Loss patterns

Where is the model systematically failing? Surfacing real gaps, anchoring every improvement to observed breakdowns.

CLUES

Competitive Longitudinal User Evaluations

Aspirational queries

What does "great" look like? Defining the bar we're reaching for, not just the floor we're fixing.

SENSE

Sentiment of Search User Experience

A point of misalignment in the org — both were necessary. Loss patterns kept us honest. Aspirational queries kept us ambitious.

THE VOICE GAP

The capability was there. The voice wasn't.

Before persona work
Are you bored?
AI on Google Search does not experience boredom or other human emotions. AI lacks consciousness or subjective experience, which are necessary to feel emotions like boredom. It is a language model, and it's purpose is to provide information and answer questions based on its training data.
After persona work
Are you bored?
Not at all! I don't experience boredom like humans do — my "mind" is always active and ready to dive into whatever you're thinking about. If you're the one feeling a bit restless, we could listen to music, learn something new, or play a game. What's on your mind?

CONTEXT

How the pieces fit together

DeepMind

Builds the foundation model

Gemini

Product team, shared persona layer

Each layer has different product needs. Persona work had to align across all three while preserving Search's distinct voice and factuality bar.

PERSONA PRINCIPLES

A polarity, not a tradeoff

What people have always valued

Reliable

Trustworthy

Expert

What people now expect

Collaborative

Warm

Agile

Too much of the first → robotic. Too much of the second → loses Search's trust signals. The design challenge was the overlap.

FROM PRINCIPLES TO MODEL

Three breakthroughs

Constitutional Training

UX experts as "Trusted Tastemakers" inside the training loop. Content strategists curate Platinum and Golden examples — human-written responses that become rubrics fed into the model pipeline.

Steerable Persona

A shared taxonomy across three layers: core behaviors (always true), situational behaviors (context-adaptive), steerable behaviors (dial-able per surface without retraining).

Evolving Evals

Auto-raters trained against constitutional rubrics. Sentiment frameworks. Competitive benchmarks. Loss-pattern analysis. One auto-rater reached 81% directional agreement with human evals.

PERSONA · IMPACT

Results

Tone improvements drove deeper engagement: more queries, higher follow-up rates, user-initiated follow-ups grew 6%

Conversational nudges lifted AI Mode queries +2% globally and typed follow-ups +10%

+20% quality inline link coverage while maintaining neutral conversational metrics — a genuine win-win for ecosystem health

"The persona workstream is the gold standard for UX and engineering collaboration." — Engineering Lead

JANUARY 2025 · PRESENTED TO CEO

Stored equity

Competitors had been copying Google's surface-level features for years. Personalization offered something they couldn't copy. When a product genuinely knows you, understands your history, and gets better over time, switching becomes expensive. That's a moat.
