Marikina City, Philippines (PressExposure) July 26, 2008 -- As a marketing strategy for increasing a site's relevance, Search Engine Optimization or SEO considers how search algorithms work and what people search for.
SEO efforts may involve a site's coding, presentation, and structure, as well as fixing problems that could prevent search engine indexing programs from fully spidering a site. Another class of techniques, known as black hat SEO or spamdexing, use methods such as link farms and keyword stuffing that tend to harm search engine user experience. Visit the SEO Philippines to learn more of this.
Spamdexing involves a number of methods, such as repeating unrelated phrases, to manipulate the relevancy or prominence of resources indexed by a search engine, in a manner inconsistent with the purpose of the indexing system.
Some consider it to be a part of search engine optimization, though there are many search engine optimization methods that improve the quality and appearance of the content of web sites and serve content useful to many users.
Search engines use a variety of algorithms to determine relevancy ranking. Some of these include determining whether the search term appears in the META keywords tag, others whether the search term appears in the body text or URL of a web page.
Many search engines check for instances of spamdexing and will remove suspect pages from their indexes. Also people working for a search-engine organization can quickly block the results-listing from entire websites that use spamdexing, perhaps alerted by user complaints of false matches. More information on this can be found with the SEO Philippines.
The success of Google at both producing better search results and combating keyword spamming, through its reputation-based PageRank link analysis system, helped it become the dominant search site late in the 1990s.
Although it has not been rendered useless by spamdexing, Google has not been immune to more sophisticated methods. Google bombing is another form of search engine result manipulation, which involves placing hyperlinks that directly affect the rank of other sites.
Common spamdexing techniques can be classified into two broad classes: content spam (or term spam) and link spam. For more information about SEO and SEO techniques, then visit the SEO Philippines at www.myoptimind.com for more details.
