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.

PRODUCT PRINCIPLES
Broad queries represent both a core strength and opportunity
Users should know whether SRP will fulfill their need by the end of the first viewport
After answers, should be diverse, immersive, inspiring, and personal
Maintain and build upon the core strengths of classic blue links
Improve the taste and cultural relevance of content on SRP
Provide users rich information right at the top of the page, while helping them orient to what's available on SRP.
Create a more fresh, relatable, and diverse SRP through current, human content and personalized experiences.
Enable user exploration through a composed, guided, and more continuous SRP experience.
Deeply satisfy users' information needs, and bring the wealth of the web to SRP through rich & intuitively browsable results.
Make information journeys more efficient and enjoyable, through a dynamic and tailored page that gives users agency.
GROWTH ANALYSIS
Speed and efficiency are the largest drivers of growth
How We Operated
Come with a hypothesis
High bar to ship, low bar to experiment
Endorse or Improve
Define success criteria early
Horizontal zones dedicated to user need
(explore, learn, focus)
One view, same content,
tuned to your preferences
Expressive, magazine-like layouts of all formats. Can be dense, can be spread
Push & Pull pathways to enter users into exploratory or detailed focus zones
Modular inline morphing to mutate the srp based on user engagement for a tempo change focus
Dynamically adjust the visual experience via controls

Case Study 2
SEARCH · COMPETITIVE CONTEXT
AI MODE · GOOGLE SEARCH
AI Mode needed design velocity infeasible in the traditional SRP due to business and ecosystem constraints.
Search drives the majority of Google's revenue. A separate surface contained the risk.
UXR pointed to the same finding: people wanted Search to be Search. A new surface honored that.

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.
Stateful recall

AI OVERVIEWS · 2024
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
AI Mode was a CEO-level initiative — every Search team contributed. My org took on several 0→1 initiatives across two key areas:
SRP → AI Mode entry points, reconciling disparate top-of-page experiences
Conversational design strategy, voice, model behavior training
Cross-K&I personalization strategy, CEO presentation, launch
Concept to Google I/O launch in 30 days
THE FUNNEL
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
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
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
Where is the model systematically failing? Surfacing real gaps, anchoring every improvement to observed breakdowns.
CLUES
Competitive Longitudinal User Evaluations
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
CONTEXT
DeepMind
Builds the foundation model
Gemini
Product team, shared persona layer
Search
Surface-specific tuning, grounding, Search's trust requirements
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
Reliable
Trustworthy
Expert
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
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.
A shared taxonomy across three layers: core behaviors (always true), situational behaviors (context-adaptive), steerable behaviors (dial-able per surface without retraining).
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
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

JANUARY 2025 · PRESENTED TO CEO
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.
Meaningfulness
Value delivered must justify data used
Empowerment
Agency at contextual and account levels
Legibility
People must see when personalization happens and how their actions influence it
"Personalized by you, not done to you."
