UX Deep Dive Mini-Series: Part 1 - Conversion Rate
One thing we don’t talk about enough in UX/Product design is how to measure and effectively communicate our impact. It’s not just about crafting beautiful interfaces or intuitive flows—it’s about showing how our work contributes to the success of the business. But how do we do that?
As a strategic designer, you need to focus on metrics that speak to both the user experience and the business bottom line. One of the most important and common metric designers use to measure impact and success is Conversion rate.
What is Conversion Rate?
Definition: A conversion rate in the context of user experience (UX) design is the percentage of users who take a desired action on a website or application. (Interaction Design Foundation)
In UX and Product Design, CR serves as a critical metric that links user behavior to business goals. It measures the effectiveness of design decisions in guiding users toward key objectives, such as:
Signing up for a service
Making a purchase
Subscribing to a newsletter
Completing an onboarding process
How is it calculated?
Example:
If 1,000 people visit a product page and 50 make a purchase, the conversion rate is 5%.
Why and when to use Conversion Rate?
CR is a valuable tool for:
Evaluating Design Effectiveness: Identifying opportunities to reduce friction in user journeys.
Aligning with Business Goals: Supporting objectives like revenue growth or increased engagement.
Identifying Bottlenecks: Detecting usability issues that block user progress.
Tracking Design Impact Over Time: Monitoring improvements after iterations.
CR is just one part of the feedback loop. To fully assess design effectiveness, it should complement other metrics and qualitative insights from usability testing and surveys.
Common UX Problems that impact Conversion Rate
Several design issues can hinder conversions, including:
Unclear or intimidating workflows.
Lack of transparency in pricing or policies.
Dark patterns that erode trust.
Unintuitive processes with insufficient guidance.
Conversion case study:
Optimizing the flight booking checkout process
Problem:
Users on an online travel agency’s website spend significant time searching for flights and entering detailed passenger information. Yet, many abandon the process halfway through checkout. Key pain points included:
Lack of clarity around refund/cancellation policies and charges.
A lengthy, overwhelming checkout process with little guidance.
Confusion over fee structures and data collection practices.
Solution:
The team redesigned the checkout flow to address these issues:
1️⃣ Increased Transparency Around Policies and Charges
Clearly stated refund/cancellation policies upfront.
Charges and breakdown (e.g., ticket price, taxes, and fees) are clear and easy to understand.
2️⃣ Progress Indicators and Progressive Disclosure
Added a progress bar to show users their position in the checkout process.
Broke down steps using progressive disclosure to focus users on one task at a time.
3️⃣ Detailed Breakdown of Charges and Data Collection
Provided line-item breakdowns for all fees with brief explanations.
Clarified why specific personal data was collected (e.g., for ticketing and security compliance).
Result:
The redesign produced remarkable results:
The conversion rate increased from 20% to 55%, significantly reducing cart abandonment.
Total completed transactions rose, driving revenue from ticket sales.
Upsell revenue (e.g., seat upgrades, travel insurance) increased due to improved user trust and pricing clarity.
Collaborating with teams to optimize conversion rates
Improving CR requires collaboration across teams. Here’s how you can work with key stakeholders:
Data Analysts:
Segment data by user groups, channels, and time periods.
Provide insights into trends, anomalies, or patterns impacting CR.
Product Managers:
Define conversion goals (e.g., completed upgrades or onboarding).
Establish KPIs connected to the product’s success.
Developers:
Validate or implement tracking for key events.
Pull data when tracking tools are not yet in place.
Customer Success/Support Teams:
Share common usability complaints and friction points.
Marketers:
Share campaign performance data and insights from A/B tests.
Getting started with tools and tracking
Familiarize yourself with tools that can help measure CR, such as:
Google Analytics
Mixpanel
Hotjar
Even if event tracking isn’t perfect, start small. Analyze the data you have, share findings, and propose improvements. As your team sees the value of your insights, they’ll be more motivated to support you.
Conversion Rate: A designer’s impact in numbers
Conversion Rate is more than just a number—it’s a testament to how well your designs serve both users and business goals. By focusing on CR, you align your work with measurable outcomes and demonstrate how design drives business success.
This metric is a key step in elevating the role of design within your organization. It’s how you build credibility, gain influence, and move closer to securing that “seat at the table.”
