I'm familiar with Google Analytics quite well, but still can't figure out how to do something that seems pretty basic.
Let's say I have a traffic increase of 20% on a certain month. Let's assume this represents about 10k increase in terms of visits. How can I understand what are the most significant contributors to the traffic increase - which pages, which acquisition sources, which search keywords, countries, etc'?
Theoretically, I can go over each section and check which entries had the most change, but beyond the reports being very cumbersome, it doesn't really provide a full picture. Ideally, I would like a report that says - of the 10k increase in visits, 5k came from an increase in "abc" search keyword, 30% came from an increase in traffic from France, and 20% came from a "xyz" acquisition campaign.
Would be happy to understand if there is a simple solution - whether inside GA or with an external tool - before I start hacking something like this for myself.
