Traffic source by page or by session
There are some other analytics tools out there in the market that track traffic sources by visits or session. That means, all of the pages in one visit have the same traffic source as the first page in this visit/session. Can I understand if Google Analytics behaves the same?
For example, if a user land on my site through search engine then he/she clicks on a paid campaign on my site and goes to another page in the same domain. In this session, both pages will have the same traffic source of search engine even though user reaches the 2nd page by accessing the paid campaign. Is this the same case for GA?
Thanks in advance for any clarification.
