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 http://example.com to www.example.com.

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?

When you redirect your example.com to www.example.com, using a 301 redirect, all your existing link-juice will also transfer to the www version. But if you're going to redirect it using a 302, that may block link-juice from flowing to www version.

So redirect your site without the www to the one with the www using a 301 redirect, and also put a canonical tag on it. That will help to prevent your pages from losing any SERP.

    Also specify the preferred domain in GWT and make sure you've verified ownership of both the www and non-www versions of the domain. Reference: support.google.com/webmasters/answer/44231?hl=en
