Bounce Rate is expressed as a percentage. To calculate bounce rate, take the number of single-page visits and divide by the total number of visits, then multiply by 100.
Vsp = Visit of Singe Page/Single time
Vt = Visit of Total page
If, on one day, a page receives 240 visits and 160 are bounces, and the next day receives 240 visits and 210 bounces, the bounce rates would be 66.67% and 87.5%, respectively. Although on the second day, the page had more bounces numerically, the bounce rate expressed as a percentage makes it easy to compare the data meaningfully and to see that the second day had a none favorable bounce rate.
