As with the question above, there are no hard and fast rules as the answer has to be tied in with the objective of the site. If it is understood from the outset that a business requires a website that will be updated rarely, if at all, then this will be allowed for in the design. (There is nothing worse than having a website referring to ‘breaking news’ that actually broke some 6-12months ago.) Having said this, there is a now also a tendency for search engine indexes to lose interest in sites that appear to be neglected. It is therefore worthwhile refreshing a site from time to time even if there is no actual news to post.
