To achieve the company's OKR, the main parts of the website that must be continuously optimized are acquisition, activation, conversion, usage, and revenue growth. My role as a UX designer improves user experience to achieve company goals by reducing user friction and enhancing self-serve experience.

To demonstrate my UX funnel 
optimization skill, I selected two projects
1) Signup to install funnel optimization

1. Signup to Install Funnel Optimization

Optimize the signup funnel in every aspect—user experience, technology, and acquisition. Find the best solution to remove any frictions in the signup process and increase successful signup numbers.

1-1. Signup Funnel Optimization


Jan, 2021

1. Why is this project important?

The company OKR is to increase the number of new user signups. After the renewal, new user signups from the website grew, but the signup success rate declined. To acquire more new user signups, increasing the signup success rate is a prerequisite. Hence, the website must optimize the current signup experience without signup churn and failure.

2. Problem Discovery 

  • GA shows signup completion rate is decreasing

  • The email verification step occurs with high signup failure 

  • There is a massive increase in low-intent users negatively impacting email click-to-open rates (other factors affecting email performance)

  • The survey step increases the bounce rate

  • The current signup step is too long for new users (5 steps)

  • There is no clear identified button for login/signup on the main page.

3. Possible Solutions

  • Reduce the signup process from 5 steps to 2 steps.

  • Add the social signup feature (Apple and Google) to simplify the signup.
    - One-click signup completion without typing personal information.

  • Remove the email verification and survey steps. 

  • Email verification is required when customers try to subscribe to a plan.

  • Use the same modal format for a quick revision.

4. Result & Evaluation

  • Accomplished over 90% signup conversion rate
    after launching the social signup and removing the email verification process.

  • The new signup process was updated on January 26th, 2020

1-2. Iteration
Signup to Install 


Feb 2021 ~ Mar 2021

1. Why Is This Project Important?

After the improvement of the signup process, the signup success rate increased, but the use of products decreased. Therefore, the website must change its goal from "new user acquisition" to "signup to install."

To achieve a new goal, I hypothesized a new UX funnel with a focus on downloads.


  • An increase in the number of downloads leads to an rise in ProtoPie studio usage, which in turn increases the revenue.

  • Users will download more if the website has a download entrance on the main page.

* Hypothesis of tactics for coping with decrease of download

2. Problem Discovery 

1) Decrease ProtoPie Studio download rate

  • Despite the success of the signup funnel optimization on January 26, 2020,
    the number of ProtoPie studio downloads significantly decreased

2) Decrease the individual plan subscription rate​ too

3) Not intuitive download entrances and page 

  • Hard to find the entrance from the homepage to the download page.

  • The characteristic of the download page is not clear

Explanation of the graph

  1. (Blue) Since January, the number of unused ProtoPIe Studio has been increasing rapidly.

  2. (Red) ProtoPie studio usage has been decreasing since the first day of subscription.

3. Solutions

Redesign download focused UX flow

A. Add a download button on GNB

  • Quick access to the download page

B. Reinforce the download page

  • Redesigned the download page to focus on the download purpose

  • Revise the hero section

    • Delete the signup CTA 

    • Show the download items directly first 

  • Copy the revision on the ProtoPie Studio and player section

4. Results & Validate the hypothesis

  • Increased download and installation rate by 20%

  • Increased usage of ProtoPie studio by 11.8%

  • Learning: Number of use is also vital as number of installs. 

  • Next phase test goal: Focus on launching the studio than on the download

2. GNB Improvement

Remove friction information exploration for self serve digital experience in GNB

Apr 2021~ May 2021

1. Why Is This Project Important?

​After the renewal, it is necessary to enhance the website self-serve experience to increase the conversion rate and lead generation. GNB improvement was conducted to offer better experience to increase the conversion rate, visiting time and find information more easily. I hypothesized about the benefits of improving GNB.


  • If GNB provides a second-depth entrance, users will be able to find pages and information quickly.

  • Providing more entrances in GNB will increase the number of page views.

  • If the number of pages related to revenue increases, the purchase and lead generation numbers will also increase.

2. Problem Discovery 

  • Hard to find sub-depth pages dut to GNB only has first depth 

  • There is no entrance to the enterprise plan page in GNB, which affects B2B lead generation.

  • Navigation scalability problem
    - Difficulty in providing information when adding a new page

3. First Unmoderated Usability Test (April 2021)


Define the current pain points that users face while doing specific tasks in the website.

A total of 8 users worldwide

  • 4 non-users who have prototyping experience

  • 4 current users, regardless of their prototyping proficiency

5. Solution 

  • Show the second menu on the current first depth GNB

  • Show categories that can help to increase revenue


  • Increase visit duration 

  • Reduce bounce rate

  • Create a helpful user experience

  • Users will be more responsive to call-to-actions

  • Improve conversions on your website


  • PV of each GNB page

  • # of plans subscription rate 

  • # of clicks subscription CTA

  • # of B2B lead inquiries

6. Prototyping & 2nd Usability Test

Second unmoderated usability test with hi-fi prototyping (April 2021)

> See the new GNB hi-fi prototype for the test

A total of 8 users worldwide

  • 4 non-users who have prototyping experience

  • 4 current users regardless of their prototyping proficiency


  • Get user feedback about the prototype of the new GNB

  • Validate navigation improvement results.

Final Deliverable & Result

After releasing the new GNB with the second depth, I tracked the data change. The website needs enough time to collect and analyze data, but I've found meaningful results from GA. The number of page traffic associated with revenue has increased. The result is as follows:
