spamdex
<World-Wide Web> (Presumably from "{spam}", "index") {word
spamming}.
"Spamdexing has come a long way from the halcyon days of the
summer of 1995. Back then, all one needed to do was add the
word 'sex' a thousand times at the end of a Web page to
attract attention from the likes of Lycos. The search-engine
operators caught on fast" -- Andrew Leonard, Hotwired 1996
