I have a question which I can't seem to find an answer for so I thought someone here might be able to give me some info.
In AdWords TOS it specifies that the browser back button must be functional on you landing page which makes total sense from a usibility POV.
What I am trying to work out is, if someone clicks on an ad then hits the back button and goes back to the SERP, does this register as an additional impression for your ad in AdWords.
From my own investigations I think that it does, however I am not 100% sure and could really do with knowing the answer / having some more information on it.
Any help / info would be greatly recieved!
I'm no expert on server headers, but what I get from Google seems to indicate that the results can be cached, but only for that user session.
I should have probably specified I am only worried about Google Search impressions, not content or search network.
Your observations are pretty much the same as mine, however using livehttpheaders in FF I get some info that seems to suggest the headers are re-sent each time you hit back button to Google...
