— Kaito [LP Creation & Ad Management]

Challenge: The Limitation of Design-first Web Development That Fails to Sell

Despite offering high-value services, Kaito-sama suffered from zero inquiries coming through their existing landing page built by another agency.

Upon deep technical and marketing audit, I identified that the previous agency aimed only at visual aesthetics, completely missing crucial marketing mechanisms such as psychological customer journey design and conversion rate optimization (A/B testing).

Solution: Conversion-driven LP Architecture Integrated with Ad Management

I built a high-performance LP infrastructure designed to act as a 24/7 top-performing digital salesperson.

  • 【Psychology-based Sales Structure】

Implemented a structured story flow based on the PASONA framework, deeply identifying target audience pain points and presenting logical solutions.

  • 【Blazing Speed & UX Optimization】

Leveraged Next.js to achieve ultra-fast mobile loading times, completely eliminating user drop-off caused by latency.

  • 【Precision Ad Management & A/B Testing】

Launched targeted Google and Social Media ad campaigns post-launch. Repeated rigorous A/B testing on headline messaging and CTA buttons to isolate the highest-converting creative and keyword combinations.

Results: Reduced Customer Acquisition Cost (CPA) by Over 50% and Project Completed

By handling the entire lifecycle from LP planning, design, and Next.js development to ad campaign optimization, results materialized immediately:

  • Cost Per Acquisition (CPA): Reduced by 【53%】 compared to previous campaigns.
  • Conversion Rate (CVR): Increased by 【3.8x】.
  • Project Status: 【100% Successfully Delivered & Operational】 as a stable automated acquisition system.

By combining cutting-edge software engineering with grounded marketing expertise, I continue to serve as a lifelong business partner driving direct revenue growth.
