Too Long; Didn't Read
Semantic HTML is a very important feature of HTML that is important to write good HTML. HTML was conceived as a semantic way to share content. Semantic content is almost always ignored by search engines. It is not a good thing for us to find a readable and understandable code. How to write semantic HTML is quite simple, follow the standards 4.0.0. The most important issue is that non-semantic HTML code is not being used in 3.0 but rather than HTML 40 is being more than semantic.
