Google Says Goodbye to Black Hat SEO

Some examples of black hat techniques to avoid:

• Keyword stuffing - Putting a bunch of keywords randomly on your website will give you a lower page rank.
• Invisible text - Putting a list of keywords with white text on white background trying to attract the web crawlers.
• Doorway pages - These are "fake" web pages that are designed to attract higher ranking with the search engine. Once a visitor lands on a doorway page, they are instantly redirected to the "real" website.

Just build your website normally and follow the Google's SEO guide, and your website will eventually be successful.
