Hi.
My backlinks are different between http://www.allucandl.com and http://allucandl.com
Are they big mistake for page rank or not?

redirect your non-www domain with www.yourdomainname.com. Also careful when collecting back links. If a website having lots of backlinks without www then the page rank vary.

In SEs view it is different your backlinks from non www and www the best thing to do for it is to use url redirection. It is very easy to do that..

Yes, simply do redirect from non-www to www, by using Google master tool:
www.google.com/webmasters/tools/
Log in and go to the "Tools", then click "Set preferred domain". When you get there you will make association of a preferred domain with your site, so it will affect Google's search results.

Have a great day,

Try to check which one has more backlinks. After that, do a redirection on the other one... SE's view it differently...

Thanks to all.

Sadly serach engines do not test if the two sites have the same content since technically it is possible to return different content on them. Hence they cause duplication.

good suggestion

Sitemaps

You should definitely redirect one to the other to avoid duplicate content issues. Not only that, if you have incoming links to both, you are essentially splitting your potential PageRank into two.

The second point is valid, but the first one should not be an issue. Doing a 301 redirect for non www urls with an htaccess if the easiest and best option.

Wrong, Google does care. Use a 301 redirect from one to the other. Check ou the G webmaster tools and set the preferred domain, otherwise it treats these as different.

Both (a) www.domain.com (b)domain.com are different links. That's why Some web directories embed www at the start of the link. If you don't want to get different results than your expectations, than try to stick with one format. I would recommend to use www at prefix of link.
