Search Engine Placement: Spamming Techniques. No Spamming
Invisible Text: Hiding keywords by using the same color font and background is one of the oldest tricks in the spammers' book. These days, it's also one of the most easily detected by search engines.
Keyword Stuffing: Repeating keywords over and over again, usually at the bottom of the page (tailing) in tiny font or within Meta tags or other hidden tags.
Unrelated Keywords: Never use popular keywords that do not apply to your site's content. You might be able to trick a few people searching for such words into clicking at your link, but they will quickly leave your site when they see you have no info on the topic they were originally searching for.
Hidden Tags: The use of keywords in hidden HTML tags like comment tags, style tags, http-equiv tags, hidden value tags, alt tags, font tags, author tags, option tags, no frames tags (on sites not using frames).
Mirror Pages: Don't duplicate a web page or doorway page, give those different names, and submit them all. Mirror pages are regarded as spam by all search engines and directories.
Link Farms: Many search engines consider the use of link farms or reciprocal link generators as spam. Several search engines are known to kick out sites that participate in any link exchange program that artificially boosts link popularity.
