This is a pretty boring post but it might be relevant to anyone doing SEO for travel sites.
I’ve noticed a few links I’ve got on lonelyplanet.com have had nofollow’s added to them. These aren’t links I’ve dropped in the forum of anything like that, its the proper links which the editors have handpicked for each location. If you look at the Mallorca guide page (yeah I nofollowed that link!) those links in the article have had the rel=nofollow tag applied to them.
