Organic vs. Medium/Organic vs. Default Channel Grouping (Organic Search): causes of differences?

I'm now on looking for organic traffic. To do so i apply to all pages (behavior→site content) second dimension and wonder about results differences:

 

1. On applying of Acquisition→Default Channel Grouping and filtering for Organic Search

 

i get same results as

 

2. on applying of Acquisition→Medium and filtering for organic.

 

But the both results differ from results i get

 

3. on applying of Acquisition→Source/Medium and filtering for organic.

 

The difference is weird too: till the number of whole pageviews is the same, the numbers of pageviews per url differ, and on applying of Acquisition→Source/Medium and filtering for organic i get different amount of urls, as in the first and second selecting arts.

 

Could somebody explain me causes of these differences?

Hi
Well I dont quite understand the purpose of having traffic source as secondary dimension at page level report.
But I tried the experiment which you described and I didnt get any discrepancy, are you facing sampling in your reports?

I know this was asked 2 years ago, but I stumbled upon it looking for a different question, but since I'm here I decided I will give my 2 cents and answer this question too. 

 

Sometimes it is hard to understand with large numbers, so let's work on smaller hypothetical numbers. Let's say you got this traffic:

 

example.com/page1

2 visits from Google

1 visit from Yahoo

 

example.com/page2

5 visits from Google

 

Assuming that was all the traffic you got.

 

1. On applying of Acquisition→Default Channel Grouping and filtering for Organic Search

 

You will see:
example.com/page1 

3 visits from Organic Search

 

example.com/page2

5 visits from Organic Search

 

2. on applying of Acquisition→Medium and filtering for organic.

 

You will see:
example.com/page1 

3 visits from Organic

 

example.com/page2

5 visits from Organic

 

3. on applying of Acquisition→Source/Medium and filtering for organic.

 

You will see:

example.com/page1 

2 visits from Google/Organic

 

example.com/page1 

1 visits from Yahoo/Organic

 

example.com/page2

5 visits from Google/Organic

 

It will appear like you have 3 URLs instead of 2. It is pretty obvious in this example but in Google Analytics, the list can be very long and is initially sorted by sessions, descending. So if there is a large difference between Google/Organic traffic with Yahoo/Organic traffic and all the Google ones are on top of the list, it isn't that obvious that the Yahoo's are listed there too, they are just way at the bottom you didn't notice them.
