I have heard about these types 1) White Hat 2) Black Hat 3) Grey Hat And "Red Hat" No much idea about this.
White hat seo means doing SEO for a site which is under googles guidelines. Black Hat means SEO which is unethical and which google hates like spamming and etc. Grey HAt means the SEO which Google hates but it is done as such that google doesnt catch.
1) White Hat - SEo used as per the GOOGLE rules and regulations. 2) Black Hat - SEo which is totally cocerned with spamming!!! 3) Grey Hat - A SEO practice which is purely black hat seo but it may not be catched by "G" eye ( Hidden links)
