  Kathy Daunt: HI All,,
  
  As said in Mozcast (http://mozcast.com/) the weather for last Friday and Saturday was too bad and I got down in Google SERP results. Is this any minor algorithm update??
  
  And after the softer algorithm update on March 24, 2014 there is decrease in organic traffic to my site.
  Is there any possibilities to increase organic traffic again?
  
  Kindly help me. Thanks in advance

  The cuetimes listed on this page are functional while the live broadcast continues and also once Youtube has finished processing the public broadcast. Processing time varies between 6-24 hours. During this period the clip is viewable in full but the cuetimes cannot be relied on. ;

  Kathy Daunt: Thanks +Edwin Jonk ; The video was pretty much useful to me. ;
  
  In SERP, my keywords went down by 4 or 5 positions down but still in page 1, but there was heavy organic traffic drop.
  
  As you mentioned I have checked the below
  
  => we didn't get any message in webmaster regarding penalty
  => we are not doing payday loan marketing
  => checked the website content and found out a bit of duplicate content and we are working on it.
  => Checked the keyword density: The keyword density of my page is 2% greater than my competitors. Does this keyword density make any sense for this 2%?
  => As this happens during softer panda update, we guess panda roll out might a be a reason for drop
  
  Let me know your suggestions? How can we recover from this?
