SEO techniques

SEO techniques are classified into two broad categories:

1. Techniques that search engines recommend  as White Hat SEO,
2. Techniques that search engines do not approve and attempt to minimize the effect of referred to as Black Hat or spamdexing.
   
   
   White Hat SEO refers to the usage of SEO strategies, techniques and tactics that focus on a human audience opposed to search engines and completely follows search engine rules and policies. For example, a Web site that is SEO optimized, yet focuses on relevancy and organic ranking is considered to be optimized using White Hat SEO practices. Some examples of White Hat SEO techniques include using keywords and keyword analysis, backlinking, link building to improve link popularity, and writing content for human readers White Hat SEO is more frequently used by those who intend to make a long-term investment on their Web site. Also called Ethical SEO.
   Contrast with Black Hat SEO.

   • Using Hidden or invisible text or with the page background color, using a tiny font size or hiding them within the HTML code such as "no frame" sections.
   • Repeating keywords in the Meta tags, and using keywords that are unrelated to the site's content. This is called Meta tag stuffing.
   • Calculated placement of keywords within a page to raise the keyword count, variety, and density of the page. This is called Keyword stuffing .
   • Creating low-quality web pages that contain very little content but are instead stuffed with very similar key words and phrases. These pages are called Doorway or Gateway Pages
   • Mirror web sites by hosting multiple web sites all with conceptually similar content but using different URLs.
   • Creating a rogue copy of a popular web site which shows contents similar to the original to a web crawler, but redirects web surfers to unrelated or malicious web sites. This is called Page hijacking.
