"SEO Studies": [Column] The Science of Thought - Let's Enjoy "Thinking"! (Part 6)

The Science of Thought Part 6: "SEO Studies" - Considering Search Engine Optimization as an Academic Discipline

1. Introduction: Can SEO Become an Academic Discipline?

SEO (Search Engine Optimization) has developed as a technique for understanding search engine algorithms and increasing website visibility. However, this is not merely a marketing method; it requires a body of knowledge spanning multiple fields such as information science, cognitive psychology, linguistics, and economics.

If SEO were to be established as an "academic discipline," what kind of research themes and curricula could be envisioned? In this article, we will design a fictional discipline called "SEO Studies" and reconstruct search engine optimization as a subject of intellectual inquiry. SEO continues to change along with technological progress, but from what perspective would you research SEO?

2. Major Research Areas of SEO Studies

① SEO as Information Science

Search engines possess algorithms that organize, classify, and evaluate vast amounts of information. The following themes would be subjects of research:

• Analysis of search engine ranking algorithms

• Methods for utilizing knowledge graphs and structured data

• Optimization of SEO strategies utilizing machine learning

② SEO as Cognitive Psychology

How do people perceive and click on information displayed on a Search Engine Results Page (SERP)?

• The relationship between eye movement and CTR (Click-Through Rate)

• The psychological impact of meta descriptions

• Search intent (Informational, Navigational, Transactional) and content design

③ SEO as Linguistics

Google is evolving into an algorithm that understands search intent and context, rather than just simple keyword matching.

• The relationship between natural language processing technologies like BERT and MUM, and SEO

• Keyword optimization vs. search intent matching

• Multilingual SEO and Translation Optimization

4. SEO as Economics and Marketing

We study how high rankings in search results affect a company's sales and brand value.

• Analysis of the Relationship between SEO and SEM (Search Engine Marketing) and ROI

• The Impact of Google Algorithm Fluctuations on Market Competition

• The Rise of Zero-Click Searches and the Decline of Organic Traffic

3. Practical SEO Measures and Academic Approaches

What exactly is SEO?
It refers to measures for search engine optimization aimed at achieving high rankings in search engine results by targeting specific keywords or phrases, and it is implemented through steps such as the following. In SEO Studies, not only theoretical research but also practical measures are important subjects of study. Here, we will explain the main SEO measures by dividing them into four categories: Keyword SEO, Content SEO, Off-page SEO, and Technical SEO.

1. Keyword SEO (Keyword research, selection, and appropriate placement/optimization)

■ Keyword Research: First, we investigate the keywords that target users are likely to search for.

Main Methods:

• Google Keyword Planner (Free Google Ads tool)

• Google Suggest (Candidates that appear when typing in the Google search bar)

• Competitor Analysis (Investigating keywords used by competitor sites)

• Search Intent Analysis (Determining which phase the search keyword is in, such as "information gathering," "comparison/consideration," or "purchase")

■ Keyword Selection: Based on the research results, we select the optimal keywords by considering the following points.

• Search Volume (If the search volume is too high, competition is fierce; if it is too low, traffic is minimal)

• Competitiveness(Check the strength of top-ranking sites)

• Utilizing long-tail keywords(e.g., compound words like "SEO for beginners" rather than just "SEO")

• Does it match the user's search intent?

■ On-page SEO:Properly place selected keywords within the page to optimize for search engines.

• Title (title tag):

  • Place important keywords toward the left

  • e.g., "What is SEO? A thorough explanation of the basics for beginners"

• Meta description:

  • Summarize the main points within 160 characters

  • e.g., "Explaining the basics of SEO for beginners. Introducing key points for keyword selection, on-page optimization, and off-page optimization."

• Headings (H1, H2, H3):

  • Always include the target keyword in the H1.

  • Place related keywords appropriately in H2 and H3.

• Body text optimization:

  • Sprinkle keywords naturally (unnatural keyword stuffing is a no-go).

  • Optimal keyword density(a guideline is 1-2%).

• URL structure:

  • Keep it short and include keywords.

  • Example:https://example.com/seo-kiso/

• Image Optimization

  • Include keywords in the alt tag

  • Example: <img src="seo-guide.jpg" alt="SEO Basics">

• Setting up Internal Links

  • Link to related articles (e.g., "SEO Basics" -> "Introduction to SEO Tools")

(2) Content SEO (High-quality content that matches search intent)

Since search engines evaluate "high-quality content," it is important to provide valuable information. Google emphasizes "E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness)," and high-quality content is required.

• Solve user problems

  • Utilize Q&A formats and diagrams

  • Present actual data and case studies

• Focus on E-E-A-T

  • Experience

  • Expertise

  • Authoritativeness

  • Trustworthiness

  • → Google prioritizes these to determine rankings

• Regular updates

  • Review to ensure information does not become outdated

③ Off-page SEO (Increasing site authority and trustworthiness)

Google views backlinks as a "proof of trust," and acquiring high-quality links is important. Acquiring backlinks from external sites improves your site's evaluation.

• Acquiring natural backlinks

  • Create high-quality content and have it introduced by other sites

  • Spread via SNS

  • Register with industry directory sites

• Things to avoid

  • Backlinks from low-quality sites

  • Self-made links (subject to Google penalties)

4. Technical SEO (Site structure that is correctly evaluated by search engines)

• Optimization of site display speed

  • Image compression (WebP format recommended)

  • Cache utilization (CDN implementation)

• Mobile-friendly

  • Smartphone optimization (responsive design)

• Implementation of structured data

  • Utilize JSON-LD to display rich snippets in search results

• HTTPS migration

  • Introduction of SSL certificates (security measures)

5. Analysis and Improvement

After implementing measures, continue to make improvements while analyzing the data.

• Google Search Console

  • Check search rankings and click-through rates

• Google Analytics

  • Understand user behavior (bounce rate, time on site)

• A/B Testing

  • Comparing effectiveness through differences in titles and headings

4. The body of knowledge required for SEO studies

To establish SEO as an academic discipline, the following body of knowledge is required.

Information Science

• Information Retrieval Theory

• Machine Learning/AI

• Clustering and Ranking Algorithms

Cognitive Psychology

• User Behavior Analysis

• Eye-tracking Research

• Cognitive Bias and Search Behavior

Linguistics

• Natural Language Processing (NLP)

7. Conclusion: Can SEO be established as an academic discipline?

It has become clear that SEO can be an academic field where information science, psychology, linguistics, and economics intersect. If "SEO Studies" is established, it has the potential to develop as a discipline that researches ways to increase search engine transparency and analyzes the social impact of search behavior.

What research theme would you add to "SEO Studies"?

Afterword

This column was created using ChatGPT. It was written as an attempt to explore SEO from an academic perspective and investigate new possibilities by utilizing generative AI technology. While generative AI is useful for organizing information and expanding ideas, it is important that the final analysis and judgment are performed by humans. As content generation by AI advances, what role should humans play? It is worth continuing to explore how generative AI can contribute to SEO research.

I hope to continue exploring new intellectual domains through the co-creation of AI and humans. How will you utilize generative AI to create new fields of study?
