I am looking at my traffic data for users that have 'not found' in the page title, which is what is title content when the server uses the 404 template. In analytics: behavior > site content > all pages, set page title as primary dimension and add filter to only include the not found page titles.I'm looking at one row in particular; I have 54 pageviews on this 404 page. Let's say we are looking at www.domain.com/page/path/level. If I add a secondary dimension of source/medium I see that all 54 hits are google/organic. So that brings me to my first question:Question 1. Does the source/medium value of google/organic mean that this exact page (www.domain.com/page/path/level) was listed in a google SERP and that is how users landed on this page? Or does it just mean that user session started from a google SERP, but then they navigated to a 404?If I change the secondary dimension to previous page path I see that 38 out of my 54 pageviews have (entrance) as the value. If I change the secondary dimension to landing page, 52 of the pageviews have the same domain (www.domain.com/page/path/level) as the landing page.Question 2. How does the value in previous page path of (entrance) differ from the landing page of a page being itself (i.e. landing page for www.domain.com/page/path/level is www.domain.com/page/path/level, meaning... it landed on itself(?) )?In google search console (previously webmaster tools) when I search the analytics of my domain I don't see the path path of the 404 that I see in google analytics. For example, I can filter the pages of my domain to find a similar path like www.domain.com/page/a/somewhat/different/path/level.Question 3. Why is that? If any traffic is listed as google/organic or as landing on itself from google, shouldn't that mean that there would be data in search console that I can see?
