Definitions for "Spamming"
For email, it is sending out mass unsolicited emails. For webpages, it is using unethical practices.
Spamming (or spamdexing) generally refers to the sending of unsolicited bulk electronic mail. It is also a term used by search engines to refer to methods that they consider unacceptable for increasing page relevancy to better ranking position.
Search engine spamming is trying to fool search engines to get a higher ranking. Examples of spamming include repeating words excessively, using keywords that are unrelated to the contents of the site, and hiding text by using the same color as the background or making the text very small. Most search engines will penalize pages that use spamming.
