  Don Vermeer: None :)
• 
  Saurabh Rawat: then what about E-A-T?
• 
  Becky Westmoreland: E-A-T isn`t a ranking factor - it`s a content goal
• 
  Don Vermeer: Becky fully agree! E-A-T is pure logic. So if you don`t product content in a very dodgy manner or in the medical field youll be fine anyhow
• 
  Becky Westmoreland: Ranking factors are actual `rules` that directly affect ranking. :)
• 
  Saurabh Rawat: Ok then there is no benefit of adding author details. Interesting

• 
  Becky Westmoreland: There is always a benefit in service to your users.

  Sam Mah: If you focus on article, you need to include those details. I think those are the approach from Google content recommendation.
• 
  Becky Westmoreland: None.
•

• 
  Philip Rinaldi: Author reputation is a ranking factor with no EAT Update, no?
• 
  Saurabh Rawat: Author is not a direct ranking factor, got it. But it helps in site authority and indirectly helps in ranking. What you guys say about this.
• 
  Roger Montti: I say no. The word "authority" means reliable or trustworthy.
  
  The myth of author signals comes from the search quality raters guidelines which was meant to be a guide for how to rate the SERPs and not a "whoops" moment where Google accidentally revealed ranking factors.
• 
  Roger Montti: There is no such thing as "site authority" as a metric or ranking factor.
  
  Links and other signals of popularity indicate the "authority" of a site.
  
  BUT... you must to sit down and THINK about what the word Authority means in the context of information retrieval.
  
  When others link to a page, that means the page is "authoritative." The word "authoritative" means "trusted as being accurate or true; reliable."
  
  THAT is important because Google and Googlers use the word authoritative but it is the SEO community that calls that word (which means accurate, true and reliable) a ranking factor when the word was used in the sense of a page being accurate, true and reliable.

  Saurabh Rawat: Thanks Roger Montti
