And people seeking real information prefer it all in a single page that they can easily search and easily print, rather than having to load page after tiny page. Designers typically use tools that automatically generate directories inside directories inside directories. Designers typically use tools that pay no attention to the HTML title or generate it automatically. But to search engines the HTML title is the most important part of the page. That is what appears as the linking words in a list of results, and when words of a query match words in an HTML title, that page typically goes to the top of the list.
Designers routinely remove old and stale and obsolete content and replace it with what's current.
You should never remove a Web page or change its directory or its file name. Simply add text to explain what has changed and provide links to the new pages that have the latest and greatest info. In other words, if you are responsible for marketing or for the overall business of a Web site, you should not abdicate responsibility for Web site design to professional designers. And you need to know enough about the value of content on the Internet and how search engines work that you can make your priorities clear and lay down clear guidelines for the designers. Tell them you want traffic-oriented Web design, not design for its own sake.
