A major Google algorithm update might be on the way

What changes did webmasters notice in Google's search results?

Not all webmasters noticed the same changes. Here's an overview of what has been reported:

• Some established websites that did not spam dropped out of Google's index early March.
  
  
• It seems to take much longer now until new websites get indexed by Google.
  
  
• Rather less relevant results have received higher rankings because some relevant pages either dropped out of the index or lost some of their inbound links.
  
  
• The Cache data doesn't seem to be updated.
  
  
• The site: and inurl: queries on Google that normally fluctuate for large websites now report the same numbers every day.

Changes like these are usually a clear indicator of an upcoming ranking algorithm update.
