Google takes into account parameters such as the quality of the site, its content, behavioral characteristics, the correct structure of the resource.

Links from Twitter, for example, are also useful for indexing in Google. The quality of a Google ADS ad campaign is also important for good ad ranking.
SEO-optimization of a website in Google is a targeted set of actions, the main purpose of which is to increase the position of the online resource in the search engine for targeted user queries. Site optimized for Google will ensure an influx of users from this search engine.
