A reliable, informative, and responsive web site can reduce cost, increase visibility, and create a positive image for the owner of that site. Behind every successful web page is an overworked and underappreciated webmaster. Webmasters make sure that the information on a site is accessible and usable; that the site is always available; that performance is good; that users can get the information that they need; and that the site can collect the information it needs to serve those users.
