In my opinion, the best way to increase quality traffic is active participation in online communities ! An easy way to unlimited traffic!
Sage words, the trick of course is finding the right community where the content of your own site is similiar or related.
For example : if your web site was a blog about custom car accessories, it would expect to attract more vistors in a motoring forum than a gardening one.
However you cannot really promote a "skeleton" for it to attract attention it needs a bit of meat on bones, preferably dripping with fresh blood...
There is an often used saying that "Content is King" , no matter how bad the layout, colour scheme or general useability of a site if people find the information inside useful they will keep coming back and tell others. With a bit a luck a small percentage of them may even click on any advertising you have making it all worthwile. The "fresh" bits are crucial, with so much content is duplicated across the web time and time again any original content is highly prized by search engines and visitors alike. This of course is hard work as you have not only to write all the content from scratch but constantly have to keep posting in a number of forums to maintain awareness of your site.
One interesting solution as demonstrated by T
he Register was to stand the problem on its head and actually create a community site where non existed before by using all the computer and technology related press releases it can find as a source of content (adding a little re-writing and a splash of sarcasm) and then allowing vistors to place their own comments after each story. Thus the visitors create the fresh content which search engines find and rank accordingly.
This "mountain to mohammed" approach could be applied to almost topic, ideally all one needs is a subject that generates three to five articles/ press releases a day across the globe, do a quick rewrite no more than say 500 words each and upload for the readers to chew on like piranha. Use a bit of signature tagging in various forums to kick start the initial visitors once things take off you can stop doing that and concentrate on just the articles or feature pieces.
