[What is Yahoo Shopping search strategy? Thorough explanation of algorithm basics and scoring]

When aiming to maximize sales on Yahoo Shopping, "search optimization (SEO)" cannot be avoided. In mall-type e-commerce, where many users search for products through a search window, search ranking is the most important KPI that is directly linked to the number of accesses and, ultimately, sales. In this article, we will systematically explain the mechanism of Yahoo Shopping's unique algorithm and the scoring elements that determine search rankings from a strategic perspective.

1. Definition and importance of Yahoo Shopping search measures

Yahoo Shopping search measures refer to all measures to display your company's products higher in the search results when users search for specific keywords. Yahoo Shopping's algorithm is designed with the idea of ​​displaying ``products that are most useful to users'' at the top, and there is a logic that goes beyond simple keyword matching.

Compared to Rakuten and Amazon, Yahoo Shopping has unique customer acquisition channels such as PayPay point redemption measures and collaboration with LINE. However, as many of the final conversions (purchases) occur via search, optimizing search rankings is the foundation of e-commerce operations.

2. “Static elements” and “dynamic elements” that make up the algorithm

Yahoo Shopping's search ranking logic is roughly divided into two axes: "static elements" and "dynamic elements." Understanding these in MECE (without omission or duplication) is the shortcut to effective countermeasures.

• 静的要素（テキスト情報）： 商品名、キャッチコピー、商品情報、カテゴリIDなど。検索キーワードとの「関連性（Relevancy）」を判定します。
• 動的要素（販売実績・店舗評価）： 売上件数、売上金額、CVR（転換率）、在庫状況、レビュー評価など。商品の「人気度」と「信頼性」を判定します。

In particular, growth in the number of sales over a short period of time (sales momentum) tends to have an extremely strong impact on search rankings.

3. 5 main items that affect scoring

As specific scoring elements (search scores), the following five items need to be improved with top priority.

1. 商品名（item_name）： 最も重要なテキスト要素です。左側に重要なキーワードを配置する「前方一致」の原理を意識するのが定石です。
2. 売上実績： 直近1週間〜1ヶ月の販売件数が重視されます。ポイントアップキャンペーン等によるブーストが有効です。
3. 在庫ありフラグ： 在庫切れは検索スコアを著しく低下させ、復帰後も順位が戻るまでに時間を要します。
4. PRオプション・広告： PRオプションの料率設定やアイテムマッチの活用により、強制的に露出スコアを底上げすることが可能です。
5. 優良配送： 最短お届け日数が早い商品は、検索結果で優遇されるアルゴリズムが強化されており、バッジの有無がクリック率を左右します。

4. First step in search strategy: Tips for selecting keywords

When starting a search strategy, there is a risk that blindly packing in keywords will be considered "keyword stuffing." First, check the "suggested keywords" and "related search words" and analyze the user's search intent. A strategy that reliably aims for high rankings not only with big keywords but also with "long tail keywords" that combine 2 to 3 words is extremely effective for newly established stores and new products.
