Web Pages that load fast are profitable! Customers click away from slow loading web pages: PPC dollars are wasted, and sales are lost. If a web page
doesn't load in four seconds or less, you are losing significat business.

Each item adds a little more, and, before long, the webpage loads slowly. Monitoring the load time of site pages will help you keep a balance between appearance, extras,
and load time.
Google penalizes slow-loading sites in their search algorithm. They don't want to impair user experience - when a user clicks on a site listed in
search results by Google, Google prefers that the site to loads quickly. The user may not distinguish between the quality of the target site and the
efficiency of Google's Search Engine Results Page.
