12. White-hat SEO

White-hat SEO includes all major types of SEO in digital marketing that abide by the guidelines and regulations of all major search engines, including Google, Bing, and Yahoo. These methods take time to yield results, so you need to be patient. However, once white-hat SEO starts working, you get sustainable and long-term results that build credibility and goodwill around your brand. 

White-hat SEO techniques comprise ethical practices to improve search engine rankings while regulating the integrity of the brand and website. The best part of this SEO type is there is no risk of getting the website banned by search engines if there are algorithm updates. So, we can say that white-hat SEO is low-risk and highly rewarding if done right. 

A few common examples of white-hat SEO are developing relevant and quality content, using keyword-rich meta tags, doing extensive keyword research, building links from high-authority links, offering top-notch content and services, developing an easy-to-navigate website, etc. 

13. Black-hat SEO

Black-hat SEO is the opposite of white-hat SEO, comprising techniques that exploit weaknesses in Google’s search algorithm to get a higher rank on SERPs. These methods don’t follow the regulations of search engines and resort to bad practices to get the website ahead, such as keyword stuffing, spammy or paid link building, cloaking to misguide crawlers, etc. 

Such black-hat SEO methods may give instant results but can get your website blacklisted or affect its search engine ranking if detected by Google. Also, you achieve short-lived results even after taking such high risks. Therefore, it’s best to avoid back-hat SEO.

14. Gray-hat SEO

Gray-hat SEO includes tactics that are neither black-hat nor white-hat, so the terms and conditions regarding these practices are unclear. Marketers use gray-hat SEO to get quick results. 

Google and other search engines don’t prohibit these strategies or mention anything explicitly regarding them, but they are frowned upon and can lead to unwanted results. However, they won’t get your website banned from search engines. So, we can say that the content you create and publish according to gray-hat SEO is ill-defined. Common examples of gray-hat SEO are excessive or suspicious links, clickbait content to sensationalize it, paid reviews, etc. Although these practices are not forbidden, avoiding such underhanded techniques is better.
