  Michael Allen Smith: I have a 15 year old website (PR 4) that will release a new version very soon. The URLs will change, but I have a redirect tool so no links will break. ;
  
  I'd like to know if it would be a risk to drop the "www." from the URL. I'd prefer to drop it, but I want to do what is best for the site. Thanks. ;

  Federico Sasso: Not a problem as long as your redirect 301s are correctly set.
  Besides, you are going to change URLs anyway, and dropping the www. part is just a normal URL change.

  happysus sait: I check with ;Screaming Frog SEO first, then I make decision to drop www or non-www.  ;
• 
  Michael Allen Smith: I tested the PageRank of my site with and without the PR. Both were 4, so I launched the new version without the "www.". ;
  
  Thanks all for the feedback.  ;
