I just noticed that when I mouse over a text ad, I get the alt text box that actually gives me the url. Is this new? I never noticed before; definitely makes it easier to block out really mistargeted ads (specially on 468x60s that don't display the url)
I almost always open links in a new tab (by middle clicking). I imagine that it's common browsing behaviour.
Not for your average ( non webmaster/geeky )surfer ..most of them don't know that the scroll wheel is for scrolling/and or clicking ..and some don't know that pages scroll..
Believe me, I have watched hundreds, if not thousands of average surfers, the people that 99% of ads are aimed at.
agree ..it's a shame image ads and flash ads didn't get this "extra"..they'd be easier to ban ..which is probably why they didn't..G makes money from image ads that "brand" ..we don't ..they just make sites look like crap.
Not sure about the alt txt, but I have always moused over ads and then looked at the status bar at the bottom of the window to extract the url as a parameter. Mostly works on text ads - sometimes the url is too long and I can't see the appropriate parameter - I suppose I could widen the window. Flash ads it doesn't work on. I don't remember about images right now (its not early)
