Sometimes users can come to your site from multiple sources.
For example, a hypothetical user could have:
- Seen your Facebook ad and clicked on it.
- Came to your site, but didn’t convert yet.
- Remembered about your company in a few days, typed its name in Google and came back to your site, but still hasn’t converted.
- Finally, the user came to your site from a remarketing campaign on Adwords and converted.
In this case, “All traffic sources” field will look like this:
facebook/cpc, google/organic, google/cpc
