spider food n.

Keywords embedded (usually invisibly) into a web page to

attract search engines (spiders). The intended result of

including spider food in one's web page is to insure that the

page appears high on the list of matching entries to a search

engine query. There are right and wrong ways to do this; the

right way is a discreet `meta keywords' tag, the wrong way is to

embed many repeats of a keyword in comments (and many search

engines now detect and ignore the latter).
