Clarification from old seomoz post

[seoug_2005]

I would need clarification from an old seomoz post -  http://www.seomoz.org/q/rankings-changing-based-on-location-within-a-country-normal

Particulary the following part -

If you type in "Clear browser cache", Google KNOWS what browser you are using and can add the "Firefox" term in on your behalf, without it being apparent to the user

What does it mean ?

Thanks

Hi,

First, when you type "Clear browser cache" in the Address Bar of Google Chrome while on Google, it does NOT clear the cache, but offers you 3 pre loaded Search result pages to choose from - one for each browser. The result page for each provides a list of sites with instructions on how to clear the cache for the browser you choose.

In IE, again it does NOT clear the cache,  sends you straight to the results page for IE, but in the latest version of Firefox it does not work at all. You can easily check this yourself in your own browser.

USER AGENT = Browser type (Chrome, Firefox, IE)

Hope that helps.

"detect the user agent in the browser"

Would you please clarify this part

It means that Google will clear your browsing history and, in theory(since I have my doubts about this) it would then offer you unbiased results and advertisements.  The part about 'google can add the firefox' just means that they detect the user agent in the browser and know which browser you're using.

Personally I'm not convinced that doing this will simply clear their little pocket of info that they have gathered though - but that's just me haha
