Search engines have rules of fair play. ‘Black Hat SEO’ companies believe it is their job to trick the search engines by employing illegitimate and unacceptable tactics to gain prominence in the search engines. BAD IDEA!
If you are caught engaging in unacceptable tactics to enhance your rankings in the search engines you will receive a very harsh penalty, which may include reducing your rankings, banning your website forever from the search engines or worse yet being sued (you did sign an agreement, remember!).
There are penalties imposed for a variety of illegitimate tactics including ‘spamdexing,’ ‘duplicate content,’ ‘link farms,’ ‘keyword stuffing,’ ‘article spinning,’ ‘cloaking,’ doorway pages,’ ‘invisible text,’ and any newly developed tactic that compromises the integrity of the search engine.
Legitimate search engine optimization does not necessitate the use of ‘Black Hat SEO’ practices. The skill and expertise of an seo professional brings you long-term value whereas black hat tactics are short-lived and potentially harmful to your business and your reputation. See ‘Black Hat SEO’ for more information. Also, you may look up all the illegitimate tactics mentioned above.
