I do not think Search Bubbling is in any way relevant to the results that I personally utilised.
I understand and accept that my history affects the ORDER in which results are presented to me,
but have seen no evidence that suggests that a specific web address will result in a destination web-site that is affected by history.
I firmly believe that an address bar target of "//xyz" preceded by "http:" should take everybody to the same website - unless there is a DNS failure in address resolution,
BUT that the destination website MAY alter the information it presents to a visitor depending upon its knowledge of the visitors :-
Geo-location (e.g. Currency in Pounds or Dollars),
Cookies,
and the Browser version and Operating System and other stuff that the browser reveals to the sites we visit.
There may also be caches that need flushing.
It is unfortunate that the forum website software mutilates and shortens the appearance of the links.
I will try my luck with a code box
http://www.piriform.com/ccleaner/download
When I click on that link it normally results in that unsecured address in the address bar
But depending upon what I have been doing it might be redirected to the secured https version.
Both the unsecured destination and the secured destination are ALWAYS (I think) the correct Piriform site.
The correct Piriform site is ALWAYS variable.
Sometimes it thinks I have Dollars in my pocket and the currency is in Dollars.
Sometimes it thinks I may be lucky and have a Pound.
The Piriform site is throughout many tests very consistent in that
Dollar currency results in Download.com plus two trustworthy download links
Pound Currency results in nothing but two trustworthy sites.
I assume that the Piriform site content is controlled by Piriform to suit marketing or management criteria.
I do not know why Piriform is so confused about my location - perhaps it would have a better idea if Starpage was not protecting my privacy from Google.
During some of my tests it seemed that if I Pasted the address into the address bar the final result was affected by whether I committed with the "Return" key or the "Enter" key.
But regardless of location confusions, if I was British there was no download.com, and if I was American then there was Download.com
Perhaps Americans need no protection from download.com and its "extras" because Download.com are afraid of hungry lawyers ![:o]()
