Q. 同一ドメインで複数サイトを運営する場合のGAのプロパティは分けるべきか?

More than 1 year has passed since last update.

A. わけない方が良さそう

  • サイト間移動は内部リンク扱いとなりリファラを取らない(ただしサブドメイン間移動はGAでは外部リンク扱い)
  • プロパティ(トラッキングID)を分けると行動フローが取れなくなる
  • よって、サイトAからサイトBにどういう経路で移動したかが一切見えなくなる

対処法

プロパティを統合してビューで分割

ディレクトリでサイトを分けているのであればディレクトリ追加・除外の設定が可能
