What is SEO in 2019?

Question

Search Engine Optimization

I want to know the opinion of professionals what is SEO in 2019?
What should you pay attention to first of all, and what actions have long lost their relevance.

Answer 1

This is an orderly, ubiquitous cult of Cargo, in which the "specialist" performs a certain kind of action recommended by absolutely marginal sources, not based on any authoritative research, completely unaware of the essence of the actions performed and not realizing the complete meaninglessness of the operations being carried out.
I am not kidding.

Answer 2

Everything is the same as the last few years.
The most correct and complete response to the user's request, meeting the needs of the target audience, a site without massive errors, fast loading speed, work to increase your brand awareness.
Translating this into SEO language:
Landing pages that respond to a user's request and give him the necessary information (including content marketing).
Competent linking improves behavioral factors and increases the average check.
No broken links, pop-up banners, extra scripts, etc.
Website adapted for mobile traffic.
Crowd marketing and awareness improvement, and, accordingly, a natural link mass.

Answer 3

You need to do everything that in the last decades ...
1. The correct structure and sequence of the site, including the URL.
2. Code optimization: validation, micro-markup, site loading acceleration, design of meta tags and attributes.
3. Content for people, with pictures, tables, drawings and videos.
