After hearing a lot about it, I went over to SitePoint and read an interesting article by a “search engine optimization expert” wherein he enumerates his list of fifteen of the most egregious techniques by which companies and individuals “spam” the search engines. What’s search engine spam, you ask? It’s using inappropriate and deceitful methods of manipulating the HTML or other elements of a site to generate a higher ranking than the site would otherwise be granted by a typical search engine relevance calculation.
