We sometimes send out links to one part of our site that is password protected, at the moment what we are doing to check if the recipient clicks on it, is to not give them the password and when they email back asking 'whats the password ?' we know they have tried to look at it and are keen to look at it.
There are several problems with the above, is there a better way we can track this ?
We use Google Analytics on our site which would currently track 'direct' visit from the email but really what id like to be tracking is to be able to set a value, perhaps in the query string something like "example.com/?=sam" and then i can see that the
/?=sam link was clicked on, I would only send out this link to "sam" so I know it was he who clicked it.
Obviously they could remove the query string, but I plan to hide it by using a hyperlink with anchor text.
Is there something like that in Google Anaytics or another way to do it?
