"Poison words, are words that are known to decrease your pages rankings if a search engine finds them in the title, description or in the url. They don't kill, they just bury pages in rankings.

Generally, people think of adult words first. Adult words (obscene) often put your page in an adult category where it is filtered out by various filters at search engines.

Newer non-adult Poison Words are being uncovered. These words don't throw you into a different category, then just decrease your rankings. Poison Words signal to a search engine, that this page is of low value.

What are some new poison words?

Bookmarks, Links, Resources, Directory, Search Engine, Forum, BBS, in their singular and plural forms are known poison words.

Some are poisonous on a page by page basis, while others are only poisonous if found in titles or urls. Search engines view pages with poison words in low esteem and rarely rank them highly. They certainly index them - and some of the data on the pages maybe of theme'ing interest, but for the page to rank high under its best and most optimized keyword is very rare."
