A useful tool users never understood
CNET Shopping is a Chrome extension that compares prices across thousands of retailers in real time. The utility was strong, but the experience right after install wasn’t teaching users why it mattered.
28.8% uninstalled within 48 hours
Exit surveys revealed a clear pattern: users found the tool confusing right after install and removed it before ever seeing its value. The only onboarding was a static page that explained features instead of showing them. My hypothesis: close the gap between install and first value, and retention follows.
Product Design
I led the onboarding redesign with a small team of PMs, copywriters, and engineers – framing the problem as a retention metric, running the research, and making the priority calls about what to cut.
What testing told us – and what we did
A competitive teardown gave me four principles: immediate interactivity, clear copy, visual demos, and progressive disclosure. Eight moderated sessions then pressure-tested the prototype.
Show, don’t tell – in three steps
The final onboarding replaced the static page with an interactive tooltip flow triggered right after install. Users pick a real product, watch the comparison tool fire live, and see the best-price indicator highlighted – no email gate, no pin prompt.
Two were hard prioritisation calls: removing email sign-up meant deprioritising a stated “power-user” goal, and cutting the pin step meant trusting that experiencing value mattered more than a reminder. Retention over acquisition.
Churn down, revenue up
The redesigned onboarding cut 48-hour churn from 28.8% to 28.1%: a 0.7-point drop, or a 2.4% relative reduction in early uninstalls, measured four months after launch. Against the team’s benchmark of roughly $100K in annual revenue per 10% relative retention gain, that maps to an estimated ~$25K.
More importantly, it validated the core bet: users keep a tool when they feel its value, not when they’re told about it. Cutting the email gate and pin step, and letting people watch the comparison fire on a real product, moved the metric that mattered.
On expert bias and hard trade-offs
Having designed for CNET Shopping before, I’d absorbed assumptions about what new users “obviously” understood – so recruiting genuinely cold participants was essential to staying honest.
The lasting lesson is a PM one: prioritising between competing business goals is the job. Sometimes the right call is to deliberately not hit one stated goal to protect a more important one.
