ワードプレスでのメタディスクリプションについて

ワードプレスでＳＥＯ対策として入れられているプラグインで多いのは「All in One SEO Pack」だと思うけど

弊社では基本導入していない。SNS関連とかＡＭＰとかＸＭＬやら便利で豊富な機能があるが、META description（メタディスクリプション）をいじりたいから。

基本クライアントは詳しくないし設定もしたくないと思うので、設定がない場合でも極力最善の状態にすべきである。

で「Meta Manager」をカスタマイズしてる。他のＳＥＯ設定はテーマで対応可能だし。

ただMeta Managerそのままだと納得できない。カスタム分類とか。

ので↓

添付ファイルページとか日付アーカイブ・404はnoindex

メタ情報の重複を極力避ける（制定がない場合も、ページネーション時も）

カスタム分類に極力対応

でこうなった。↓　カスタム投稿アーカイブのときの設定してないかも時間あるとき見直します。
