Many Web developers only know how to use the link tag to create external style sheets. But there are many other things you can use this tag for. For example, you can provide alternate versions of your Web pages - say in other languages or in print versions such as PDFs. You can also create a hierarchy for search engines and other spiders to step through by linking previous and next documents or even an index to your Web pages.


I had no idea that the use of the LINK tag was so broad. Does it have any practical value to define pages in terms of link relations? Do search engines groove to it?
