There are four main types of SEO or search engine optimization, all aimed at helping you earn greater visibility in search results:

• White Hat;
• Black Hat;
• Grey Hat; and
• Negative SEO

Here we are talking about white hat or black hat SEO that is generally used for any business or post.

Black Hat SEO : This type of SEO focuses on optimizing your content only for the search engine, not considering humans at all. Black hat SEO refers to techniques and strategies used to get higher search rankings, and breaking search engine rules.

Some techniques used in black hat SEO include: keyword stuffing, link farming, hidden texts and links, and blog content spamming.  It will often lead to severe punishment for the marketer, ruining their chance of building something sustainable in the future.

White hat SEO: White hat SEO refers to the use of techniques and strategies that target a human audience opposed to a search engine.

You’ll try to give them the best content possible and make it easily accessible to them by playing according to the search engine’s rules.  Those who use white hat SEO expect to make a long-term investment on their website, as the results last a long time.
