E-commerce Insights: The (Free) Benefits of Google’s Webmaster Central

Here’s the three-step recipe to avoid canonicalization woes:
1. Decide on the preferred base URL for your site.
2. Tell Google about your decision.
3. Have your Web servers enforce your decision using 301 redirects.

For my canonicalization, I’ve chosen “www.rimmkaufman.com” — with the triple-w prefix — as the base URL, though I still can use the shorter form without the triple-w prefix when speaking and on printed marketing materials. But the “true,” or canonical, domain has the triple-w.
