I have an established website with 1000's of links and good SERP for many of my pages. My Google Webmasters is now asking to solve an issue which is canonicalization. I prefer
www.example.com and know how to redirect
Since my site is already well developed with lot of links from various sources (a lot of them may be to
http://example.com and not
www.example.com), will it effect my current rankings?
