SEO is search engine optimization. It is not easy to explain it in few sentances. However, make it short, it is related to search engine result page ranking and google page ranking basically. And the major factor is dofollow backlink and keywords
There are two types of SEO
Onpage SEO
Off Page SEO

I prefer white hat seo, because back hat isnt stable, google always changing, its too easy to fall, white hat generates long term results.

There are three types of SEO which are as below :

Black Hat SEO : Black Hat SEO is really "bad" in the ethical sense. Black hat SEO is deemed to be sly, underhand, sneaky and even dishonest and generally practices that are not endorsed by the search engines or break search engine guidelines.

Whit Hat SEO : White Hat SEO refers to the usage of SEO strategies, techniques and tactics and completely follows search engine rules and policies.

Grey Hat SEO : Grey Hat SEO = white hat seo +black hat seo.
