Seller Decision Making Toolkit

Designed Market Insights and Demand Discovery tools to help sellers answer two key questions: "should I sell or wait?" and "how fast can I sell?" Increased iOS conversion rates by 14.8% and 26.9% respectively.

The user problem

Decision paralysis from static valuation.
Potential sellers need to answer three core questions: Is now the right moment? How fast will my home sell? What will I net? Zestimate offered a static valuation number, but zero context on market timing.

The business problem

Top-of-funnel drop-off before agent conversion.
Homeowners who get stuck evaluating “Should I sell?” churn before connecting with an agent on Zillow.

Context

Zillow earns when a homeowner connects with an agent.
The Zestimate is Zillow’s most-used free seller tool. It tells homeowners what their home is worth, but not whether it’s the right time to sell.

An opportunity to translate Zillow data into intuitive and contextual information. A unified view where homeowners easily and quickly understood their selling position.

What we built

The shipped solutions

I shipped two tools. Market Insights answers whether this is the right moment; Demand Discovery answers what a given price would mean for time-to-sell and net outcome.

Design decisions
01 Segmented meter for confidence
Already established pattern in Market Insights V1, now a part of the design system. Cheap for engineering to build and the most compact of the options, satisfying the HDP team’s 570px max height design principle.

02 A single number, not a range Sellers want one number. I didn't want to add a range to a decision that already felt confusing. A concrete number instills more confidence, so I made sure we could model a realistic single number we could stand behind.
03 Teal green color palette Green signals trust in Zillow’s new visual identity, and the number of days to sell is exactly the figure we want sellers to trust. See rejected color palettes
How I got here

Why it looks like this

Both tools went through an earlier iteration built on the data available at the time. The goal was to test whether sellers would engage with a tool like this at all, then use that signal, plus better data, to answer the real questions: should I sell now or wait, and how long will it take?

The constraint we designed inside Every mobile module is capped at 570px tall These tools live on a page owned by another team, the Home Detail Page (HDP) design team. Their design principles cap any mobile module at 570px of vertical space, so every layout had to conform to that max height.
V1 Test the appetite Ship with the data we had and see whether sellers engage at all.
Signal Read the experiment A/B results show what moved, what stalled, and which numbers sellers used.
V2 Answer the real question Better demand data: should I sell now or wait, and how long will it take?
01
The constraint

V1 tested the water with existing data, to see if sellers would engage with such a tool

Initial problem statement · Demand Discovery Sellers lack visibility into how their list price directly impacts buyer demand and engagement, leaving them deeply uncertain about the eventual success and timeline of their home sale.
Market Insights V1 · iOS

We knew sellers wanted to understand the market, and these were the four data points our data could support. We did not know which one mattered most, so the plan was to A/B test and follow up with qualitative research.

Demand Discovery V1 · iOS

The only data available at the time was the engagement a seller could expect at a given list price, which is what the design models. Sellers could also see the boost in engagement they would get with the Showcase product.

What V1 taught us

We learned in production, not in a user study

This was measured on live traffic. V1 of Market Insights was successful. Demand Discovery, on the other hand, showed strong engagement but did not move the conversion needle.

A/B tests told us what moved and what didn’t, but they couldn’t tell us why, so V2 was a hypothesis about the why, tested the same way.

03
What changed

Better demand data meant we could finally answer the question properly

The upgraded data let us model, in real time, what a given list price would likely get a seller, and show how much confidence Zillow had in that number.

The constraint that shaped V1 had lifted. That reframed the question from how to present a coarse signal well to what this should be now that we could actually answer it.

Reflection

What I would do differently

I would unify both tools into a single connected flow from day one to understand how users used the two tools together rather than in isolation. Launching them sequentially created a handoff gap between evaluating market timing and modeling price scenarios, which required a subsequent sprint to bridge.
