This is the rate at which people click on a link and is usually expressed as a percentage of the ammount of times the link was displayed. If a link was displayed to 50 visitors but only 5 of them clicked on it, the click through rate (abbreviated to CTR) was 10%.
Cloaking
Cloaking is a much frowned upon technique of configuring a site to deliver different web pages depending on the species of the visitor. If the visitor is a human being then the server displays a page designed solely to make money (generally through hidden advertising buttons and a complete lack of readable content) or trick the visitor into handing over secret passwords; whereas if the visitor is a search engine spider then a cloaking page of well-formed, content-rich, advert-free html is served up to fool the search engine regarding the site's real purpose and thereby improve future visitor numbers. Cloaking is a violation of Google's Terms Of Service and is both annoying and potentially dangerous for people who accidentally stumble across these sites.
Error page
Most servers are set up to display a page stating "File Not Found" or a similar message when a request for a page fails. These are also known as 404 pages after the error code that the server generates. Clever websites can use these pages to help the visitor try a different way of searching for the information they were originally seeking.
