There are four basic types of SEO:
- White Hat SEO
- Black Hat SEO
- Grey Hat SEO
- Negative SEO
White Hat SEO
In search engine optimization (SEO) terminology, white hat SEO refers to the usage of optimization 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 website that is optimized for search engines, 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 website. Also called Ethical SEO.
White hat SEO techniques involve providing users with quality content that is accurate, relevant, and well-organized. Using relevant keywords in the title tag, h1 tag, and anchor text of inbound and internal links are examples of white hat SEO
Black hat SEO
Black hat SEO refers to a set of practices that are used to increases a site or page’s rank in search engines through means that violate the search engines’ terms of service.
The techniques of black hat SEO involves
- Hidden text
- keyword stuffing
- article spinning
- Doorway Pages
- blog comment spam
Some people view them as a fast track to achieve higher rankings. In fact, many SEO practitioners believe black hat SEO tactics are useful and they encourage others to use them.
Grey Hat SEO
Gray Hat SEO is an SEO practice that’s riskier than White Hat SEO, but one that may or may not result in your site being banned from search engines and their affiliate sites.
Gray hat describes a cracker who exploits a security weakness in a computer system or product in order to bring the weakness to the attention of the owners. Unlike a black hat, a gray hat acts without malicious intent. The goal of a gray hat is to improve system and network security. Gray hat SEO involves
- Purchasing old domains
- Duplicate content
- Link buying
- Social media automation
- purchasing followers.
What is Negative SEO
Negative SEO refers to the practice of using the black hat and unethical techniques to sabotage a competitor’s rankings in search engines. Negative SEO attacks can take a number of different forms:

- Building hundreds or thousands of spammy links to your website
