  Diego Santos Sicardo: Hi,
  Yesterday traffic completely dropped off one of our pages.
  Traffic to the rest of the website has not been affected at all but these two pages have flat lined.
  I have checked rankings on these keywords and they both return on page 1 as they always do so they can be found. ;
  I have no crawl errors or manual actions in webmasters and tracking code seems fine. ;
  Can anyone make some advice? ;

  Mark Steenbakkers: +Diego Santos Sicardo did you find out what caused the sudden drop off?
• 
  Diego Santos Sicardo: not yet. Traffic is back to normal but we had several hours with no traffic at all

  Mark Steenbakkers: The pages flat lined for a few hours and then they recovered? You didn't make any changes to the pages? Server update or something like that?

  Diego Santos Sicardo: Yes. That’s right. Nobody was at the office when it happened so we are pretty sure it wasn’t something we did. It seems as if that page disappeared from the SERP for a while...

  Mark Steenbakkers: There were some Google algorithm updates, maybe Google was testing an update. There was some turbulence on the Google algorithm weather report http://mozcast.com/

  Diego Santos Sicardo: Thank you for your input, +Mark Steenbakkers ;. I also think that’s the most likely explanation. Still very odd.
