Final answer:
The measures of traffic volume are 'visits' and 'time on site', which help to quantify visitor activity on a website. 'Bounce rate' and 'margin' do not measure volume; 'bounce rate' tracks visitor behavior and 'margin' is unrelated to website traffic.
Step-by-step explanation:
The measures of traffic volume are typically indicators that show the quantity of visitors and activity on a website. These measures help businesses and webmasters understand how well their site is performing in attracting visitors and how engaged those visitors are. Statistics that are commonly used to measure traffic volume include visits and time on site. On the other hand, statistics such as bounce rate give insights into the behavior of visitors, but do not directly measure volume. Also, margin is not a measure of traffic volume.
- Visits - This refers to the total number of times users enter a site.
- Time on Site - This denotes the duration of a user's stay on the website during a visit.
When determining traffic volume, visits and time on site are two important metrics that reflect the level of user activity and engagement. These measures are critical for evaluating the success of a website and can be used over time to track growth or changes in user behavior.
