Google shows my URL differently

.... why me?

[internetheaven]

On the Google results pages my listings are shown fine but the URL (the one in green) is shown differently to my competitors:

[example.com...] folder/file.html

Whereas my competitors are shown as:

[example.com...]

This is the case for files on my dynamic site aswell:

[example.com...] folder/file.php?product=1234

Whereas competitors get the normal:

[example.com...]

My rankings are good and I'm above many of the sites that have a normal URL listing so I figure I haven't been penalised in any way. The pages aren't new, they've been on Google for about 4-5 months so I am at a loss to explain it.

Is your domain longer than the other site's domain? Google insert the space when the URL might cause problems to users of narrow-width screens.

hi ciml,

is there any other reason why Google might add that space? Is the clustered result more likely to have a space becuase it is indented?

[ciml]

As far as I know, the space is only added to stop horizontal scrolling (you may have noticed WebmasterWorld threads with URLs adjusted for 'scrollism').

I don't know if indented listings have the space more often, but I have noticed that the URL-length for adding the space doesn't seem fixed.

The added space in a domain is purely for formatting purposes so that all those poor people who think it's "kewl" to surf the web on a cellphone with a 1-inch screen won't risk any sideways scrolling. It has absolutely no influence on the result itself.

Do I sound cynical there? ;)

ciml's explanation seems to work for me. I'll leave it there then, as long as it's not some 'Sandbox', penalty, dynamic issues etc.

Thanks
