Thanks Franze. Downloaded.<p>Quoting a few lines from the book:
A lot of SEO folks believe(still) this is true.<p>"Google has denied that Google Analytics and Google Adsense data is used to determine user experience signals for Google Search. Fact is that we don’t know exactly how Google collects UX data, but they do, and they are magnificent at it."
Especially when they talk about "bounce rates"
