I have been asked to review an old website to an identify opportunities for increasing search engine traffic.

Whilst reviewing the site I came across a strange loop. On each page there is a link to printer friendly version:

http://www.websitename.co.uk/index.php?pageid=7&printfriendly=yes

That page also has a link to a printer friendly version

http://www.websitename.co.uk/index.php?pageid=7&printfriendly=yes&printfriendly=yes

and so on and so on.......

Some of these pages are being included in Google's index.

I appreciate that this can't be a good thing, however, I am not 100% sure as to the extent to which it is a bad thing and the priority that should be given to getting it sorted.

Just wandering what views people have on the issues this may cause?
