Referrals in Web analytics are sites that brought (referred) people to your site via link. Referrer report gives you information where do your visitors come from, what are your traffic sources.
We can divide referrers into 4 groups:
- Direct entry – all visits created by direct visit, or when info about real referrer is missed because any reason
- Websites – referrals from others websites
- Campaigns – referrals from others websites but with tagging parameters
- Search engines – entries from Google, Bing, DuckDuckGo etc.
