I remember reading ages ago that it's a good idea to choose either www.example.com
or domainexamplecom
as your main URL and then set the other one as a 301 redirect to point to your domain?
The reason provided was:
- Some people may link to
www.example.com
- Other links may point to
example.com
In order to not lose 'SEO link juice', the individual recommended setting up a 301 redirect from one to the other.
Has this changed? Is it true? I would have guessed that Google (and other search engines) would be smart enough to whack some code in their algorithm to understand that in most cases www.example.com
= example.com
?
