あなたのサイトのmetaタグのクオリティを分析します。

We used to insert specific page description, keywords, and other metadata in website's HTML for search engines.
かつては、検索エンジン用にタイトルや、キーワードをHTMLに指定していました。

However, now that people uses a lot of applications on mobile such as Facebook, Twitter, and other native applications, it's important how links to a website look like on those platforms.
しかし、現在は多くのユーザーがFacebookやTwitter、多くのネイティブアプリケーションを利用しているので、それらのプラットフォーム上でサイトへのリンクがどのように表示されているのかが重要になりました。

We have to add a lot of meta elements into website's HTML in order to increase page views. It's so difficult to remember which elements do you need for your site.
PVを上昇されるためには、多くのmetaタグを挿入する必要があり、どの要素が必要かとても覚えられる量ではありません。

You can learn your site's meta condition easily by using this extension. After installing, this extension will start analyzing. When you finished loading a website, the site's score is shown over the icon. If you'd like to learn more information about the score, click the icon. You can see which elements were needed, and which passed or not.
このChrome Extensionをインストールすると、簡単にあなたのサイトのmetaタグの状況がわかります。サイトを読み込んだタイミングで必要なmetaタグが挿入されているか分析を開始します。分析結果は、スコアとしてアイコン上のバッチで表示され、ひと目でそのサイトのmetaタグのクオリティがわかります。さらに詳しい情報を知りたい場合には、アイコンをクリックし、popupを表示させます。popupでは、どの要素が足りていて、どの要素が不足しているのかを知ることができます。
