Sharing that happens in private channels such as WhatsApp, DMs, email and text messages, which analytics tools cannot trace. Visits from these shares usually show up as direct traffic. The term was coined by Alexis Madrigal of The Atlantic in 2012.
Example
A customer forwards Meera's product link to her sister on WhatsApp. When the sister opens it, Google Analytics records the visit as direct, with no sign that it came from WhatsApp or from the original Instagram post.
How you'll hear it
“Half our direct traffic is probably dark social; people are forwarding links on WhatsApp.”
What it helps you decide
How much credit to give social content when analytics shows little traffic from it. It pushes businesses to ask customers how they heard of them and to put tracked links on share buttons.
Where people misread it
Direct traffic is read as people who typed your address or already knew you. Much of it can be private sharing that started on social, so cutting social content because of low tracked traffic can remove what was driving sales.
The story
Meera's website has a WhatsApp share button on every product page. Her paid ads bring 10,000 sessions a month. Her Google Analytics report for everything else looks like this.
| Instagram posts (tagged links) | 1,500 |
| Google search (unpaid) | 1,000 |
| Direct | 2,500 |
| Total sessions not from ads | 5,000 |
|---|
Outside paid ads, Direct is the biggest source, at 50%. Her agency reads this as people typing her web address because the brand is well known, and suggests cutting Instagram content.
Meera starts asking every online buyer one question at checkout: where did you first hear about this product? Of 240 online orders in the month, 60 said a friend or relative sent them the link on WhatsApp. That is 25%.
Those links carry no tag, so analytics cannot see where the visit came from and files it under Direct. Many of those forwarded links were first found on her Instagram.
Meera keeps the Instagram content, adds a 'How did you hear about us?' question to checkout and in-store billing, and puts tagged links on the share button.
All figures are fictional and illustrative.
Don't confuse it with
- Direct traffic: the analytics label where dark social lands, but it also includes people who typed your URL or used a bookmark.
- Shares (sends): the platform's count of shares; dark social is about what happens after the link leaves the platform.
In India: WhatsApp is the most common way links are passed on in India, which makes dark social a large blind spot in Indian website analytics.
