Source of Visitors is broken into two parts by a drop-down menu to display Number and Percentage of visitors that have entered your website through various sources.
For example, GA is tracking your website traffic which you are also advertising on your social media platforms, and every time when a user clicks on this link, taking them to your website, it counts as a referral as the source of these visitors had come from Facebook, Instagram, etc.
To find these metrics please log in to Google Analytics
1. Under Reports, click on Acquisition
2. Click on All Traffic
3. Then click on Channels
4. Select Date search parameter to match the Tile (Day, Month or Year)
On the Channels page, click on Source tab situated just above the table of statistics
Source of Visitors reads data from the Sessions column. These are not unique users, as the same person can engage with your website multiple times a day and it will still be registered. As soon as you have 1 user on your website, 1 session is registered and the percentage starts at 100%. This percentage is then divided by subsequent sessions according to their source throughout a date period.
In the above example, we can see that there was a total of 5 sessions (5 users visited your website) which means that 100% is divided by 5 = 20% per session
2 sessions were registered via Instagram, 2 via a Wix Website and 1 via Facebook
20% x 2 via Instagram visits =40%
20% x 2 via Wix Website visits = 40%
20% x 1 via Facebook visits = 20%
