Under the graph, you should see some general statistics regarding visits to the site. Among these statistics is the average visit duration. This is the average time spent on the site as a whole during single visits. A visit is a single user session on your site. Specific Pages. Rather than viewing average durations for the pages in your site as a whole, you can use Google Analytics to determine the average time spent on specific pages. With the main Content page presented, you should see a list of the pages visited under the line graph and general statistics. To calculate average session duration, Analytics sums the duration of each session during the date range you specify and divides that sum by the total number of sessions. For example: 1  Total Session Duration: 1000 minutes (60,000 seconds). 2  Total Sessions: 100. 3  Average Session Duration: 1000/100 = 10 minutes (600 seconds). If there are engagement hits on the last page, then the duration is calculated as follows: The time of the last engagement hit on the last page-the first hit on the first page. For example: 1  Page 1: first hit: 10:00 AM. 2  Page 2: first hit: 10:05 AM. 3  10:15 minus 10:00 = a session duration of 15 minutes (9 Time on site or visit duration can be an indication of the level of interest or involvement that a visitor has with the website. It is also a good indicator of the success of a campaign or other promotional activity that brings visitors to your website.  Average Visit Duration. When you first log into and view the Google Analytics interface and select your site, you will typically be presented with the Visitors Overview for the whole site, normally over the last month. A line graph plots the traffic your site has received each day during this period. Specific Pages. Rather than viewing average durations for the pages in your site as a whole, you can use Google Analytics to determine the average time spent on specific pages. With the main Content page presented, you should see a list of the pages visited under the line graph and general statistics. Goal. Decrease the office visit cycle time to 30 minutes or 1.5 times the actual time spent with clinician. For example, if the average patient spends 20 minutes with a clinician during the office visit, then the goal for the office visit cycle time would be 30 minutes (1.5 x 20 minutes = 30 minutes). Data Collection Plan. Sample a minimum of 15 patients per week on a pre-selected day and time.  Here the average visit duration of the site is 4 minutes and 6 seconds. The average visit duration for the traffic coming from Google Organic search is: 3 minutes 29 seconds. The average visit duration for direct traffic is: 4 minutes 6 seconds. The average visit duration for traffic coming from Linkedin is: 6 minutes 41 seconds and so on Now for the time visitors spend on site. Average Session Length (ASL) measures the average amount of time a visitor spends on your site or on a particular page. If you got 4,000 visitors this month and they spent a total of 29 hours on your site, the average session length was 26.1 seconds.  Thank you Avinash! The issue I am facing is that the Bounce Rate I am seeing for a specific referrer (search engine x)on GA is relatively low (between 5-10%) but the average time on site for that source is very low as well ~50 secs. The average time for the website overall is ~ 6min. Every page is coded properly. If you have a high bounce rate and a high average time on page, then the user was interested in your content but only wanted to look at the one page. However, if bounce rate is high and average time on page is low, then there is a problem because Google factors in time on page for rankings. So instead of relying on site average metric (here 4 minutes 6 seconds), we analyze and report the ‘average visit duration’ of each traffic source. This is the very first but important step to analyze average visit duration. The average visit duration for the traffic coming from Google Organic search is: 3 minutes 29 seconds. The average visit duration for direct traffic is: 4 minutes 6 seconds.
