I am viewing this Google Analytics report for one page on my website:Google Analytics > Behaviour > Site Content > Secondary Dimension > Source/MediumI've also tried using this method with the same results:Google Analytics > Behaviour > Landing Page > Secondary Dimension > Full ReferrerThe entries in the list of results include the followinggoogle / cpc  (Google AdWords)EDM / email (clicks from emails that are tracked)(direct) / (none) (no medium/source tracked)google / organic  (Google Search)website / referral  (websites that link to the page)bing / organic (Bing Search)These are all fine.My question is about some GA campaign codes which appear in this list as well.  These campaign codes are used on links that do not link to the page I am analysing.  I would expect that traffic via a campaign code must link directly to the page otherwise, they should not appear in the list.  Other campaign codes that do link to the page also appear in this list and are fine.Why do campaign codes appear in this list if they are not used to link to the page being analysed? Is Google Analytics tracking users who subsequently visit the page after clicking a link with a campaign code?
Why do GA campaign codes appear in source/medium lists when they don't link to the page?
