Multiple Clicks Cost You Money

This post is from from my other blog here

When one person clicks on one advertisement multiple times in the same session, AdWords will record multiple clicks while Analytics recognizes the separate pageviews as one visit. This is a common behavior among visitors engaging in comparison shopping.

There is NO mention of the second and third (or more) clicks on my same ad being counted as invalid. I know that the particular campaign I was looking at had a 4% invalid clicks rate...but the data discrepancy was much much much higher when looking at my website analytics reports.
