rankings improve when I change url on English version of site

[member22]

Have any one experience this issue ?
my website is in English and French and the english version of my webpages is

www.example.com/en/example

However if take the /en out and have the following web address instead

www.example.com/example my ranking improves greatly !

why is that ? anyone experienced this ?
Thanks,

Those are two different urls, so I would expect them to show different results. If the content is the same for both versions of the url, then you have a duplicate issue that you should fix. There is a significant section dedicated to duplicate issues in the Hot Topics area [webmasterworld.com], which is always pinned to the top of this forum's index page.
