everflux
Once a month Google updates its entire index of web sites. That is called the Google Dance and can last for a couple of days - usually it's from about the 20th to the 28th of every month. Around June/July 2002 we started seeing something else though. Google results started changing all through the month, in between the major updates. This continuous change became known as everflux. It happens because Google, in an ongoing effort to make their results as relevant as possible, has introduced a "fresh crawl" that runs each day. The idea behind the fresh crawl is to update pages that change regularly. This allows Google to serve results that are up-to-date with current events.

Excite

One of the major search engines. For a detailed look at Excite and the other major search engines, please refer to our detailed discussion in the Search Engine Yearbook.

expert document
A document that links to many other (same-topic) documents. Some search engines only consider links from expert documents - as opposed to all documents in the collection - when determining link popularity. According to the Hilltop paper, expert documents are "pages that have been created with the specific purpose of directing people towards resources".

eye candy
Aesthetically pleasing web sites are said to provide eye-candy. The term is used to describe sites both positively and negatively. In the context of search engines and SEO, eye candy is generally perceived as unnecessary, not contributing to the marketing effort.
