Black Hat search engine optimization is customarily defined as techniques that are used to get higher search rankings in an unethical manner. These black hat SEO techniques usually include one or more of the following characteristics:

breaks search engine rules and regulations
creates a poor user experience directly because of the black hat SEO techniques utilized on the Web site
unethically presents content in a different visual or non-visual way to search engine spiders and search engine users.

White Hat SEO
Any SEO tactic that maintains the integrity of your website and the SERPs (search engine results pages) is considered a "white-hat" search engine optimization tactic. These are the only tactics that we will use whenever applicable and which enhance rather than detract from your website and from the rankings.
