No technical measures and SEO can be used to optimize the way Google interprets and evaluates data, thereby increasing positioning for relevant search queries. Manipulations, as in the past through black hat SEO, backlink spam, and other techniques, are no longer so easy today thanks to various quality mechanisms and algorithms (spam detection). There are always gaps (exploits/glitches), which are fixed very promptly by Google. In terms of quality, this has the advantage, especially for users, that they see good and relevant content as a search result.
