Uptick in not tracked conversions / anyone have a list of things that google analytics will not track

[Gordian]

There seems to have been an uptick in users on our site not being tracked in Google Analytics cause I see a lot more un-tracked revenue in the last 6 months then I used to. I know analytics is still working as it has been tracking a normal amount of visits but I assumed there might be a reason less would be actually showing up in analytics (mabye a change is what is being reported as organic).

I know a lot of stuff goes into "not provided" such as logged in search and stuff like that but is there a list of all of the ones that go into not provided and all that just do not get tracked (javascript not enabled, iOS?).

If it could be something else as well let me know. Thanks for the help!

Hi Gordian,

So one main issue with not provided results is being on secured connection ie logged in to Google and their suite of products. But with that could be other issues for example:

Last year starting with Firefox 14 it opted to use all secured searches when searching on Google.  I don't assume good chunk of your traffic just upgraded their Firefox accounts. But maybe other browsers, smartphones etc jumped on the same "secure-search" bandwagon recently? Just an idea.

Hope this helps
