I would start by identifying relevant content publishers or potential partners in your vertical and contacting them to discuss how you could work in partnership, some people may be happy to have some free content and others you may have to barter with. You will probably have to invest a fair amount of time in establishing these relationships.

A word of warning, be wary of targeting keywords in these external articles that will be high priority keywords for your website. If the content is being published to a authoritative domain you may struggle to rank above these articles even when your domain authority increases.

I don't know if you have budget for PPC but this can be a great way to drive traffic to your site whilst your organic presence is in it's infancy.

Hope this helps.

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?
