Google Analytics 報表包括維度(dimensions)與指標(metrics). 說明如下:
維度(dimensions): 是「非數值性」的描述使用者特徵, 階段、行為動作。常用的維度例如: 使用者的區域, 國家, 所使用的瀏覽器等等.
指標(metrics):  是「數值性」的描述使用者特徵, 階段、行為動作。常用的指標例如: 訪客數(visitor), 瀏覽數(pageview), 轉換率(converstion), 跳出率(Bounce Rate,使用者進入網頁後無後續動作即離開網站)等等.

C.The site only has one page (e.g. a simple blog).
