A Link is normally a hypertext entry which lets the reader jump to a new location. In current Web use, it specifically means a Web address , or URL, which, when clicked on, transfers the reader to that location. This has its good and bad points. The good point is that by linking to interesting and relevant sites, you can provider your readers with much more information than you could write on your own. You can show information from independent analysts and industry authorities.
Links are information.
Readers like them. Site designers love them, because they add so much content for so little work. But as a marketing manager, you have to keep a firm grip on how many and where the links are. These may be a courtesy, or they may be contractually required. For example, some Web Awards require that if you display the award, you always display a link back to the awardgiver's site.
