Try the new AdSense interface,

As with many others here, I've been using this for a few months (because I applied for and got a beta invite).

I loved it because it included a "Sites" report that showed AdSense statistics by domain name, without the need to set up URL channels. Better still, the "Sites" report included AdSense statistics for Google-hosted properties including Knol, for which URL channels cannot be set up.

Unfortunately, Google removed this feature a couple of weeks ago (maybe because they realised it was revealing more data than they intended it to).

So now, I actually prefer the old interface because it requires fewer clicks to get a report on "yesterday's earnings by channel". And the old interface works on a 960-pixel-wide browser window without annoying horizontal scrolling.

Any screenshot please?
I see no difference.

Which feature did they remove, the one about being able to see your domains without setting up channels? (Or the one where you can see Knol etc.?) When I click on the "join the new version" button, I also still get the old version. Not having to set up URL channels seems like a really useful feature tho.

I still get the old version too, even in US English.

Philipp: They removed the "sites" option. Without that option, you cannot see stats for Knol etc, and you also cannot see stats for your different domains unless you set up URL channels. Both of those were really useful features.

Here's how Google announced the removal of the feature (in an email from AdSense on 13 October):

<<As you know, we’ve been beta testing a new version of the AdSense account interface ... While testing, we’ve realized that one feature, the Sites report, isn’t yet ready for full launch. The Sites report allows you to see domain and subdomain reporting without setting up URL channels. After careful review, we’ve decided to remove the Sites report from the new AdSense interface. You’ll notice that the Sites report has been removed from your account in the next few weeks.>>

The Sites report would be almost trivial for Google to provide, especially compared to all the fancy stuff offered by the new interface, so I think the reason for removing the feature must have been a policy decision rather than any kind of technical problem.

That's a pity, because the Sites report was the one really good thing about the new interface.
