SEO (Search Engine Optimization)

Also known as: Search Engine Optimization / 検索エンジン最適化

The practice of improving a site's visibility in search engine results through technical, content, and link-building optimizations — increasingly intertwined with LLMO in the AI search era.

Overview

SEO covers three pillars: technical optimization (speed, structured data, mobile), content quality (E-E-A-T, Helpful Content), and backlink acquisition. Since 2024, the rise of AI Overviews and AI Mode means ranking in the classic ten-blue-links sense is no longer sufficient — LLMO principles for citation probability are equally important.

Key Technical Factors

Improving Core Web Vitals (LCP, INP, CLS) and implementing JSON-LD Schema.org markup allows search engines to accurately understand page content and authority. See our practical SEO design checklist for an actionable implementation guide.
