I wonder if I should do some link farming for my clients. It would help all of them with SEO, and it would not be seen by anyone except the search engines if I use some a css “display:none” technique (as the search engines can’t see javascript or CSS). It would really help to improve rankings.
It would be awesome to have their sites make a php call to a central server to get updated lists of links to promote on their sites (invisible, of course), and maybe use some caching to keep the load off the development server.
