Why?

All web sites need to be maintained in order to keep them up to date. Some sites need daily updates while others only need occasional maintenance.

Website maintenance includes revising, editing, or otherwise changing existing web pages to keep your website up to date. The periodic addition of new web pages is also part of maintenance services.

The rules by which search engines list sites change constantly. Without updating and taking account of these new rules, a web site can easily become 'lost' in search engine listings.
