A hypothetical scenario -

I've noticed that the top 2 ads on a search result page are repeated on the bottom of the page as well. So, if the user scrolls down to move to the next page, the no. of impressions won't double up..right? It would still be 1 impression for the top ads?

Now, hypothetically, if I click on one of the top ads and open it in a new tab and also do the same for that ad at the bottom of the page, would it be counted as 2 clicks?
By any chance, would this mean that the ad received 1 impression and 2 clicks? or is it 1 impression 1 click? or 2 impressions, 2 clicks?

Its just a thought!

So, are there any chances of gaining a higher CTR in MSN for the top 2-3 ads as compared to Google?
