So let me understand this, if I post a link to have someone visit my site and they visit my site, then they click on an ad, does Google Know where that person came from originally? Meaning Person click my link from SiteA, then goes to my site SITEB, then they click an AD, does google actually know that person was directed to my site from SITEA???
Google logs IP addresses (that's your unique internet protocol address for your computer) and they can tell where visitors have come from and where they go, they use this information to prevent fraudulent clicks. The only thing that would cause suspiscion is if the same person was constantly clicking on your ads.
Thanks, but will google know that they came to my site form like Youtube and when they got to my site they clicked on an ad? So my question will google know that the person was originating from Youtube?
There is software you can download that will give you this information. Marketers can get this information, too...if they want it. I don't care where my visitors have been; I just want them to stay on my site.
You should be able to track this using Google Analytics. You can set "goals" to track specific outbound links that users are clicking out on.
I know some scripts can determine from where you come from and where you go after by reading on your cookies or browser history that information, as sites like Google and other eCommerce sites haves refinated tools to do such task.
When a server is accessed, they know your IP, your browser information (as provided by your browser software), the URL you came from (again, provided by your browser software), and your cookies, if any, related to their server. That's it. So that's what Google can collect on you, and how they can track people.
Ok so if people visit my site they will never know that they came from my youtube link, just from m y site
It is certainly possible, but I don't know if it is actually being done. I'm on the road right now and don't have time to inspect AdSense code. But theoretically, G could include within the AdSense code a very common function that gets the "referrer" from the server. In your example, the referrer is site A. If the Adsense code running on site B requests the referrer URL, it get site A's url and can then write it to an Adsense database for inspection later.

They know everything...and so does your employer. One simple example of knowing is to go from the US to Canada and then go to Google. You will go to google.ca not google.com cause they know where you are coming from.
