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).
