I have 2 travel related websites and would like to exchange links with other travel related websites.

This is a 3 way link exchange, which is much more powerfull than a normal link exchange because it looks like a regular vote from one site to another. It looks like this.

My site A links to your site B = One Way link to your site
Your site B links to my site C = One Way link to my site

If you are interested please visit http://www.localtraveldirectory.com

Just go to the appropriate category to add your website INSTANTLY. No minimum PR required, just a travel related website is needed.

The site is still pretty new, so there is no PR due to the fact that Google hasn't updated this yet, if they ever will....
