This question already has an answer here:
After Google's penguin 2.0 - I call it dracula - my website has lost about 30% or more of its traffic. The following screen shot from my Google's webmaster tools account should demonstrate the disaster:
I decided to change the title tag of some of its pages - they are 6236 pages exactly - and rearrange the order of those pages contents. I have done this from more 4 days ago and I does not able to see the new title tag in Google's search results.
From this question's answer on this community they said on Google it may take couple of days! I need to know if there is something else I have to consider? or what's the issue that makes Google delay updating my website's regarded pages modification?
