One of the minor "visitor effectiveness" elements rated in The Winery Web Site Report (1 point out of 100) is whether a winery offers an RSS feed and/or a Web log (blog) on their Web site. As I've noted earlier, there just aren't very many wineries that blog. Nevertheless, we still think that a well-written blog with weekly updates can be a powerful way of connecting with the visitors to your Web site.
Still, we acknowledge that there are wineries which simply should NOT blog, and Dave Taylor explains it well in his post on When A Business Should NOT Blog. Although his example focuses on professionals (opticians!) selling their expertise, it could just as well be a winery selling the experience of their wines.
