SEO is one of the dynamic concept in the web. It seems changing by the new trends. Google currently gives importance to AMP sites over non-AMP sites. Considers website speed based on different aspects which can be checked by pagespeed. It seems the visitor count is still important. Backlinks both internal and external seems still important as it help the bot to track the importance of pages. Properly structured content will help both the user and crawler to organize the contents. Snippets are great to have.
It is better always to have some SEO expert working on the background.
