Amazonの商品名につきまして、全角50文字以内がルールだと思います。しかし、実際には全角50文字以上入力出来てしまいます。 SEO的にはキーワードを多く入力した方がいいと思うのです、全角50文字を超える事によるデメリット（ペナルティ）はあるのでしょうか？

ECマスターズの海老塚です。 > SEO的にはキーワードを多く入力した方がいいと思うのです、全角50文字を超える事によるデメリット（ペナルティ）はあるのでしょうか？ Amazon商品名の基本ルールとして下記があげられます。・メーカー・ブランドのほか、商品の型番や仕様を含めた商品の正式名称を記載する・商品と関係のない文字や記号は入れない・付属品については「商品仕様」「商品説明」の欄に記載する・「激安」「最安」のほか、割引率を示すワードは使用不可その他、割引率やセール、キャンペーン訴求等のワードは利用できません。上記のような内容が商品名に入力されていた場合は、Amazonより指摘があり商品は「検索対象外」とされます。その後、継続して修正されない場合は「出品停止」になる可能性ございます。確かに、全角50文字以内で入力（スペース含む）が基本ですが服＆ファッション小物カテゴリーなどでは 65文字までとカテゴリーによって文字数が異なる場合がありますので、入力できる最大値まで入力して頂いて問題ありません。下記、商品名のガイドラインマニュアルがございますのでご参考にしてみてください。 ■商品名のガイドライン https://00m.in/FPbJN amazonの場合は、ガイドライン通りに登録することが、 SEO的にも推奨されておりますので、ご確認お願いいたします。
