News: In November Google rolled out breadcrumbs display in SERPs. The idea is that when a URL for a listing is too long it will be replaced by a breadcrumb, to help a user understand the context of that web page. Google quotes

“Some web addresses help you understand the structure of the site and how the specific page fits into the site hierarchy. For example, consider a search for the biography of Vint Cerf (Google’s Internet Evangelist). The URL for one result, “www.google.com/corporate/execs.html,” shows that the page is located in a page about “execs,” under “corporate,” which is on the “google.com” site. This can provide valuable context when deciding whether to click on the result.

Often, however, URLs are too long, too short, or too obscure to add useful information.“

Tutorial : This week we are going to look at the importance of internal linking for both usability and search engine optimisation. We have put together an example together that distributes a set of keywords throughout a simple 3 page website.
