How Does Ad Tracking Work?

[Dennis M. Marks]

I know that ad companies can track sites that contain their ads that
you have visited. This is used to tailor the ads that you see. Does
anyone know where I can find detailed information on how that is done.
This is just for my own interest.

Well, probably like affiliate programs do.

They give you an affiliate id that goes in all the links. Every time the
link is clicked, a script runs that updates a DB.

So, your link looks like
<a href="myCompany.com?affiliate=yourSite">your link</a>
When someone clicks on that to go to myCompany.com, myCompany.com's page
looks at the affiliate parameter and updates their database saying that
your affiliate got another clickthrough.

I can't think of any more detail that could be needed.
