Capturing Users with Content — Celebrity Saju, MBTI, and the Five Elements Quiz

 

No matter how many features a Saju app has, the act of "checking my chart" is a one-time event. You visit for the first time, see your reading, find it interesting, and then what? There's no reason to come back. We found the answer to this problem in content.

The Difference Between Features and Content

Features show results when a user provides input. Saju analysis, compatibility analysis, daily fortune. These are the app's core, but they don't inherently drive repeat visits. Your Four Pillars don't change.

Content is different. Things to read, explore, and share. "So this is what that celebrity's chart looks like," "My MBTI connects to my Day Master this way," "Which of the Five Elements is strongest in me?" Content that sparks curiosity draws users back.

Recognizing this distinction was one of the project's turning points — the moment our vision expanded from a Saju "analysis tool" to a Saju "content platform."

Celebrity Saju — CelebrityListPage

"What does this person's chart look like that they became so successful?" Anyone interested in Saju has wondered this at least once.

The CelebrityListPage analyzes real public figures' Four Pillars based on their publicly known birth data. We organized them by category — entertainers, entrepreneurs, athletes, historical figures — with each person's natal chart and key characteristics summarized.

The feature served three purposes. First, curiosity hook. Seeing a celebrity's chart alongside your own makes Saju analysis feel more tangible. "This person has a strong Indirect Officer profile, which explains their leadership" — connections like this make users examine their own charts more deeply.

Second, search traffic. Keywords like "[celebrity name] Saju" or "[celebrity name] Four Pillars" carry steady search volume. Celebrity Saju content exposed to search engines creates natural inbound traffic paths to the app.

Third, educational value. Explaining abstract concepts like Ten Gods or chart patterns through a real person's life makes them far more understandable. Showing that someone with a Direct Seal pattern actually excels in education or scholarship is more effective than defining the concept in isolation.

AI helped significantly with organizing celebrity data — collecting publicly available birth information and summarizing each person's chart characteristics. However, since birth time information is rarely public, we had to implement a separate mode that analyzes only the year, month, and day pillars without the hour pillar. This was an edge case we should have anticipated during design but only caught during implementation.

MBTI-Day Master Mapping — MbtiIlganPage

MBTI is currently the most popular personality classification system in many parts of the world. A Saju Day Master can also be viewed as one of 10 personality archetypes. What if we connected the two systems?

The MbtiIlganPage explores correlations between 16 MBTI types and 10 Day Masters. For instance, the similarities between ENTJ and Gap-Wood, or the commonalities between INFP and Eul-Wood.

Honestly, this isn't an academically rigorous mapping. MBTI and Four Pillars study are completely different systems. But the curiosity of "My MBTI is INFJ — what would that be as a Day Master?" is genuine and widespread. Content that finds the "intersection" of two systems has entertainment and exploratory value.

The most important design consideration was "not packaging it as if it has scientific backing." At the top of the page, we included a disclaimer: "This mapping identifies similarities in personality descriptions between the two systems and does not claim academic validity." Entertain without misleading. This ethical boundary is something humans — not AI — must determine.

When I asked AI "Which MBTI type most resembles the personality traits of Gap-Wood?", the answer was surprisingly persuasive. Gap-Wood's characteristics of being upright like a great tree, having strong self-respect, and being growth-oriented align with ENTJ or ESTJ. We ran this analysis for all 10 Day Masters, then human-reviewed the results to finalize the mapping table.

Five Elements Quiz — OhengTestPage

"What's my Five Elements balance?" That single question captures the entire Five Elements Quiz. Answer a few simple questions, and learn which of Wood, Fire, Earth, Metal, and Water is strongest or weakest in you.

The purpose was clear: lowering the entry barrier. Saju analysis requires knowing your exact birth date and time, and the results are complex. The Five Elements Quiz gives simple, intuitive results like "You have strong Fire energy." Anyone unfamiliar with Saju can try it without hesitation.

The intended user journey: someone takes the Five Elements Quiz, becomes curious about Saju, then wonders "What's my actual Five Elements ratio in my real chart?" — and proceeds to the full Saju analysis feature.

AI collaboration was effective for question design. "Create 20 personality/tendency questions that can identify each of the Five Elements" produced a solid draft. Questions like "In conflict situations, do you tend to confront directly (Fire) or step back and observe (Water)?" After removing duplicates and adjusting balance, the draft significantly accelerated the overall workflow.

Day Master Characters — IlganCharacterPage

The 10 Heavenly Stems — Gap, Eul, Byeong, Jeong, Mu, Gi, Gyeong, Sin, Im, Gye. These become the Day Master that represents "you" in your chart. Each carries unique personality traits.

The IlganCharacterPage visualizes each of the 10 Day Masters as a character. Gap-Wood is a tall pine tree, Eul-Wood is a vine or flower, Byeong-Fire is the sun, Jeong-Fire is a candle flame. Alongside these images, we present each Day Master's personality, strengths, weaknesses, suitable careers, and relationship tendencies.

This page functions as a "beginner's guide" to the Saju domain. A newcomer can instantly grasp "I'm a Byeong-Fire Day Master — they say I'm like the sun" without wading through technical jargon. Minimizing terminology and centering on metaphors and imagery dramatically improved accessibility.

AI's results when asked to "describe each Day Master's personality using nature metaphors" were impressive. Beyond simple personality descriptions, it captured how the same Day Master manifests differently depending on season and environment. Gap-Wood born in spring is a tree bursting with growth; born in winter, it's a tree enduring the cold. This depth elevated content quality.

Glossary — GlossaryPage

The biggest barrier to entry in Four Pillars study is terminology. Ten Gods, chart patterns, Favorable Element, Heavenly Stem combinations, directional combinations, Hidden Stems. For newcomers, every term is unfamiliar. The GlossaryPage was built to lower this barrier.

Rather than a simple dictionary, we divided terms into "beginner," "intermediate," and "advanced" tiers, so beginners see only the essential 20 terms first. Each entry includes the original characters, meaning, plain-language explanation, and a real-life analogy. For instance, "Indirect Officer" is explained as "the force that controls you — like a boss at work, discipline, exams, or external pressure."

The glossary's SEO value was substantial too. Searches like "what are the Ten Gods," "Favorable Element meaning," and "chart pattern definition" are among the most common queries from people just developing an interest in Saju. Users who arrive through these keywords and gain understanding are prime candidates to try the actual analysis feature.

The Effect of Content on SEO and Retention

The difference between features-only and features-plus-content was clear. Adding content pages dramatically expanded the keywords our site appeared for in search engines. From one keyword cluster (Saju analysis) to diverse clusters spanning celebrity names, MBTI types, Five Elements quiz, and Saju terminology.

Retention shifted too. With only analysis features, users visited once and left. With content, behavioral patterns emerged: browsing the celebrity Saju list, comparing Day Master characters with friends, studying terms one by one. The app's character shifted from "tool" to "exploration space."

The Five Elements Quiz and MBTI-Day Master mapping in particular were highly shareable content. "It says I'm 70% Fire energy!" shared on social media becomes organic viral marketing. With this sharing potential in mind, we added the ability to save result screens as images.

What This Process Taught Me

First, an app isn't complete with features alone. Features are tools; content is the reason users stay. Especially in a domain like Saju where analysis results don't change, content is the core driver of return visits.

Second, AI excels at generating content drafts at scale. Celebrity Saju analyses, quiz questions, Day Master character descriptions, glossary entries — repetitive-yet-domain-specific text that AI generates quickly and humans review proved to be an efficient production model.

Third, content tone and depth must match the target audience. The same Saju term explanation reads differently for experts versus beginners. We targeted beginners and calibrated all content accordingly.

Coming Up Next

We have features and content. But Saju apps have a unique problem other apps don't face: "I entered the same birth data but got different results from another app!" Late Night Hour (Yajasi), True Solar Time, daylight saving time — calculation methodology options that vary by school of thought, now available as user-selectable settings. Part 18 explores how this differentiator was born.
