Do users of Google Conversion Tracking or Google Analytics have more of their 'invalid clicks' go uncharged or refunded? That thought occured to me today in thinking more about the Tuzhilini Report, in particular the section discussing 'What Google Knows'. Dr. Tuzhilini makes it clear that Google gains tremendous advantage in fighting click fraud when they have access to post-click information.

So does this advantage result in tangible improvements on an individual account basis? I'd really like Google to answer that question.

BTW: Matt Cutts took up the topic today, as did WebMetricsGuru (who created a quick summary).
