What is Dwell Time?

滞在時間とは、訪問者が検索エンジンの結果ページに戻るまでに Web ページで費やす合計時間を指します。

A high dwell time indicates that the content was helpful to the visitor, while a low dwell time suggests that the content was not helpful.

Google does not consider the dwell time as a ranking factor, but results on page one of Google often have a high dwell time. However, it appears that Bing may consider dwell time a ranking factor.
