  Pankaj Asopa: Anybody have any deep thoughts on knowledge panel?
  
  I am working on achieving the headquarter and social profile thing but it is not coming, I tried almost 3 weeks but no luck so far.
  
  Any views on this?

  Jim Munro: +Tim Capper ;? :)
• 
  Morten Madsen: +Pankaj Asopa ;- Your result is a local business (based on the directions option), right?
  Wouldn't it then be irreelvant for Google to show the headquarter address? ;

  atul kumar: Business profile can be shown easily with your brand and this can be done through implementing JSON-LD Markup to the site, i think this post will be helpful for you.

  Masatake Wasa (wasaweb): With regard to social media profiles, please read https://developers.google.com/structured-data/customize/social-profiles. I agree with +Morten Madsen ;on HQ.
• 
  Pankaj Asopa: +atul kumar ;I already added schema markup but it is not showing. I suspect this is due to that social profiles are not verified thank to  ;+Masatake Wasa ;  ;I read it and followed the same. ;

  Pankaj Asopa: +Morten Madsen ;Thanks for replying, this panel result came when I searched the exact term of business name in google, not sure with the direction thing, however the business operates in multiple country that is why I need to show the headquarter address, or at-least can point service area.
  I already added schema code but don't know why it is not reflecting.
   ;
  Seems I am doing something wrong in here. ;

  Vulcan Lau: On my site I did implement the schema few months ago, but the site still display the same when googled it.
  
  It's the same like this post. Wonder what's going wrong?
• 
  Pankaj Asopa: +Vulcan Lau ;I searched a-lot on this issue and came to know; social profiles will be displayed only when they are verified, or your business/page/site is very famous.
  
  I am stuck with schema and output, I am not sure on which thing this output actually depends, I am going to give a try on Google Freebase as came to know the description is coming through freebase and wikipedia.
  
  But still awaiting experts review/advice!  ;

  Masatake Wasa (wasaweb): Freebase was a good option, but it's not going to be around for long: https://plus.google.com/109936836907132434202/posts/bu3z2wVqcQc

  Tim Capper: Yep. I have yet to see a non authority site receive the markup in the knowledge panel.
  
  Don't panic. Like everything with G it will take time for them to even start looking for the markup on .'normal' sites

  Pankaj Asopa: +Tim Capper Thanks for your input :)
