Phantom click

No idea what page triggered it

[UserFriendly]

I got a small number of clicks yesterday. One is listed next to a custom channel, but none of the URL channels that match that custom channel have a click next to them.

All of the clicks can be assigned to a page and a section except this one click which seems to belong only to a custom channel.

How can a click appear on a custom channel, but not on any URL channel? My URL channels cover every directory and content page of my site.

Is this a glitch that will later be resolved, or am I making a common mistake somewhere?

One of web user may have opened that page from Google/yahoo/MSn cache.
As Your google adsense code contain the custom channel it credit that click to that channel but page URL does not belog to any of your site.

Good answer. I reckon that would have the observed effect.
