Maybe stupid question ☺️
I have google analytics on my adobe muse sites. But do google analytics only show me traffic from google? What about does other search engines?
GA shows all traffic that is trackable by Google via whatever means of unique authentification - cookies, HTTP referrers, active Google log-in sessions, GA code on other pages. Whether that's from a direct Google search or someone linking your site, including other search engines, doesn't matter. That said, of course relying solely on Google is not representative. There is any number of ways traffic can be obfuscated and results being skewed - from servers modifying headers to users not allowing cookies to "no follow" links.
