How do you see what sites are giving me impression's?

I go to check my adsense today and got roughly 2500 impression, but only around 360 impression's are showing from which sites they are coming from.

How can I find out what sites the rest of the impression's are coming from? it is kind of annoying to have impression's, but not be able to tell where they are coming from.

 

Setup a channel for each website.

 

i think its hard to determine this. Perhaps someone trying to make a sabotage

 

yes, you can set up a channel for what you think is the most populated , etc. subdomains, sepereate domains etc on your site.

 

Or maybe your just paranoid, lol.

 

Well, I have sold some sites in the past that had the channel set up with adsense, but I think the new owner just took out the tracking codes leaving the adsense upon the sites, don't ask me why they would do that. I have sold so many websites like this that I forget which ones. I know I should take out the adsense out, but thought it would bring in more revenue this way until they change the code themself. Wouldn't I need the channel code setup on the website in order to track it that way? Is there a link on adsense that shows where all the impression's are coming from? My sites are not that popular for it to be sabotaged.

 

Setup channels for sites you want to track, so other impressions you get won't skew things.
