Black Hat SEO
The opposite of White Hat SEO, these Search Engine Optimization, or SEO, tactics are attempts to trick the Search Engines to get better rankings for a website. Using black hat methods will eventually, if not immediately, get your site drastically lower rankings or banned from the search engines altogether. While there are completely legal and ethical techniques you can use to improve rankings, if you design and market a website mostly for humans and not for the search engines’ Spiders, you should be okay.
