If you use firefox there is a "Web Developer Toolbar" that has a "View Source" tool where you can view the source of any iframe on a page. You can then look at the source of the adsense code - it often has urls in there however they are quite often hard to determine as there might be a url like 26hl%3Den%26client%3Dca-pub-564565426adU%3Dwww.site.comsjhjkds
So just fish through and in the example above you can kinda tell the advertiser.

As far as I know looking at source code is no violation of TOS. The main point is don't click or visit the url to make sure it's not registering a click on your site.

It is not what I want. I want to know what URLs my site visitors will see. What you suggest is to see what URLs I see.

Thanks anyway. It seems to a very challenging work.

Use google's adsense preview tool (IE only afaik). It will give you an overview of the ad inventory. You can change geolocation to have a peek at what foreign visitors are seeing as well.

I don't know, but it must append the users IP and the current page, as ads are targeted to location and page content. The page seems to go through as text, not a hash, as a first visit to a never before published page will contain keywords relevant to the keyowrds in the filename.

Adsense premier publishers can access that source info more directly. Does anyone know if G still allows for new premier publishers?

I want to know exactly what my visitors will see.

I don't think I can use JavaScript or other client end technologies. Either JavaScript or Flash has strict policy (for security reason) on cross domain information fetching.

Sounds like server end solution is the only solution.

By the way, my idea is very simple: Knowing what site visitors are going to see and then making some custom work to increase CTR.

e.g:

I want to know in advance that my visitors will exactly see ads from domain1.com, domain2.com,domain3.com in adsense. I get site thumbnails of these three sites from Alexa and display them next to respective ad.

Does it comply with TOS?

Not allowed, plus, the ads are random depending on what the user is looking for, you cannot guarantee you will display the correct sites thumbnail AND putting images next to ads to draw undue attention is against G's rules

You cannot know exactly what your visitors will see - even the preview tool is just a guess. What with personalization, you will *never* know for sure what your visitors see, unless you are looking over their shoulders as they visit.

And even if you did know, as mentioned above, what you want to do is strictly against TOS.

With some programming, we can know exactly what the user will see.

Basically, when a user visit mydomain/abc.html, I will make a daemon to record visitor's IP and sending this adsense content request to google (along with other adsense parameters, like web page url, client #, etc). The daemon gets response from google and then return abc.html and google ads to visitors.

Technically, it is feasible.

You're overlooking the "yeah, but" that wheelie34 brought up. Images next to ads were a big thing a few years ago until the folks at G shot them down.

So, even if you could, you can't.

A good rule of thumb for 'I've thought of this clever and different way to use Adsense' is to check with the Adsense team to be sure they are happy with your plan. This is a good rule of thumb because Adsense bans are lifetime bans, and I am sure that would make you sad.

From what you describe, I am sure they will tell you that your proposal does not meet the Adsense Terms of Service, for at least two reasons: they no longer allow images beside the adblocks and they do not want us to have ad-level control (they won't even tell us where our clicks go). This means that if you were to carry it out, you would be banned from the program.

Hope it helps.
