What is SEO? Search Traffic Basics and the Importance of E-E-A-T for EC Managers

Experience: Does the content contain firsthand information or genuine product usage impressions?
  • Expertise: Is the writing based on specialized knowledge in the specific category?
  • Authoritativeness: Has the site earned industry recognition and quality backlinks?
  • Trustworthiness: Is the site secure (HTTPS), transparent about the operating entity, and credible?

    • The reason SEO is called a 'stock-type asset' for EC sites is that it continuously acquires users with 'active purchase needs' at low cost. While paid channels like listing ads offer immediate results, traffic stops instantly when you stop spending—SEO builds lasting organic traffic as a digital asset.

    3. EC担当者が遂行すべきSEOの3大構成要素

    The unavoidable concept in current SEO strategy is 'E-E-A-T.' These are the four pillars for measuring content trustworthiness, specified in Google's 'Search Quality Evaluator Guidelines (SQEG).'

    TechnicalSEO

    The three core SEO components that EC managers must execute are: ① Technical SEO (site architecture, page speed, mobile optimization), ② On-Page SEO (content optimization, keyword mapping, internal linking), and ③ Off-Page SEO (backlink acquisition, brand mentions, social signals).

    Off-PageSEO

    Search intent analysis and keyword mapping form the core of SEO strategy. Classify keywords by user intent: Informational (seeking knowledge), Navigational (seeking specific sites), Commercial (comparing options), and Transactional (ready to purchase).

    ContentSEO

    Create high-quality blogs and product descriptions based on user search intent to expand indexable content.

    4. Search Intent Analysis and Keyword Mapping

    The era of selecting keywords based solely on search volume is over. What matters is deeply understanding the 'problems to solve' behind search terms. 'Information Gathering (Know),' 'Comparison (Do),' 'Purchase (Buy)' — by mapping appropriate LPpages and articles to these user phases, CVR（Conversion Rate）を最大化させることが可能.

    FAQ

    Q. How long does it take for SEO to show results?
    A. Generally, initial results appear within 3-6 months, but for competitive keywords, a 6-12 month strategy may be necessary. The key is consistent quality content creation and technical optimization.
    Q. Is SEO still effective for EC sites that primarily sell on marketplaces?
    A. Absolutely. While marketplace SEO has its own rules, having a strong owned-media SEO presence builds brand authority, drives direct traffic, and reduces dependence on marketplace advertising costs.
