  I don't know why but the articles without authorship show the profile links of other authors in google #SERP who have added whole blog in their contributor to sections.

  Neeraj Kumar: +Evgenii Neumerzhitckii I have checked the posts without author Google+ links in #webmaster, there is no #author data but in #SERPs, wrong author G+ link and profile image is showing.

  Evgenii Neumerzhitckii: Hmm, is it a bug? Can you provide an URL to such page?

  Tim Capper: Hi +Neeraj Kumar ;Google will attribute authorship based on the first link they find.
  
  They are most likely attributing authorship to articles that are not from that author from the landing page, where the snippets of the articles are.
  
  Landing page:
  
  bla bla bla -read more
  
  bla bla bla - read more
  
  bla bla bla - read more  ;(contains author a )
  
  bla bla bla - read more (contains author b)
  
  Author a will now be attributed to all.
  
  I have also seen cases, where the authors attribute is at the bottom of page. In this instance the comments where above this after the article - someone added rel=author link to their name, and google attributed them as the author.
  
  The best way to handle multi author:
  
  The author has their own Authors page. Thsi is where they have a bio and introduction, they also have their articles listed that they have published.
  
  This is where you attach authorship and this is the link they add to : contributor too.
