[Yahoo Shopping What is the product name? Basic rules that newcomers should know and MECE management techniques with character limit]

The "product name" in Yahoo Shopping is not just a name, but the most powerful SEO variable that influences search traffic. We have sorted out the questions faced by personnel who have just been assigned to the EC division, such as ``How many characters can I enter?'' and ``What kind of symbols are unacceptable?'' from a MECE (no omissions, no duplications) perspective. In this article, we will thoroughly explain the optimal character count design based on official rules and structuring methods to maximize sales.

1. Basic specifications and character limit for Yahoo Shopping product names

There is a system upper limit for product names (product names) on Yahoo Shopping and a valid range for display in search results. The maximum number of characters that can be set on the management screen (Store Creator Pro) is 75 full-width characters (150 half-width characters). However, on the smartphone version of the search results screen, only the first 30 to 35 characters are displayed, so the golden rule is to ``frontload'' important keywords to the left.

2. Index priority of “product name” that affects search ranking

In Yahoo Shopping's search algorithm, product names have a higher scoring weight than "catchphrase" or "product information." In particular, exact matches and prefix matches between search queries and product names are powerful factors that boost display rankings. Rather than simply listing keywords, arranging them in a word order that matches the user's search intent is a shortcut to improving CVR (contract rate).

3. Organize with MECE! 4-slot model with product name configuration

To help new staff create product names without hesitation, we recommend the "slot model", which consists of the following four elements. This allows us to mass-produce SEO-friendly titles while preventing information leaks and duplication.

• スロットA：ブランド・メーカー名（信頼性の担保）
• スロットB：コアキーワード（「財布」「メンズ」等の大カテゴリ名）
• スロットC：特徴・ベネフィット（「本革」「大容量」「送料無料」）
• スロットD：型番・スペック（「2026年モデル」「サイズ」等）

4. Checklist of prohibited items to avoid violation of guidelines

Yahoo Shopping has strict guidelines regarding product names. If you violate the following prohibitions, you run the risk of being excluded from search (penalty), so regular inventory is required.

• 以外の装飾記号の多用（★や♪などは原則NG）
• 無関係なブランド名の記載（「〇〇風」などの比較表記）
• 同じ単語の執拗な繰り返し（「財布 財布 財布」など）
• 送料無料などのプロモーション情報のみで構成される名称
