Ok google analytics shows bounce rates which means google watches the bounce rate of your site. What we are led to believe (we were inquiring as to why we were seeing so much of this in our log files) is an effective google bowling strategy which is to punch in different pages from your website into a browser and go to the different pages and only stay there a second. One can use aol ip's for this which can be changed by logging in and out, or proxies. Now someone runs up your bounce rate and google downgrades your site listings thinking you are a link farm, or getting indexed with keywords deceptively like perhaps using sophisticated redirects. The google bowler would need to do this without the google toolbar installed to avoid google picking up the same toolbar. With analytics google collects the info on your site from your site, the google toolbar is not necessary. Of course you could disconnect analytics and this would stop this from working but not sure on the impact this would have with google. If your bounce rate is 77% and a competitor has a bounce rate of 40% he is going to score well against you. Another google bowling attack using bounce rates is to use aol for different ip's or proxies and run searches, click on your site when it comes up and leave the site in a second or less. This accomplishes the same thing. To fool google one would need to have a google toolbar clone built that can be randomized so as to appear to be different each time in googles eyes. This may be difficult. Other way is to run without a google toolbar and just click on the listings as they come up. Check your log files and see if this is happenning to you, we did and were shocked to see it, we were just never aware of what to look for. In the old days we had six good search engines to work with so no one engine meant that much, now thanks to monopolies we all have to live with the awful omissions, mistakes, policies, practices of the big monopoly because the government will not enforce the anti-trust laws anymore.
