Duplicate Content Issue WWW and Non WWW

[Michael4g]

One of my sites got hit with duplicate content a while ago because Google seemed to be considering hhtp, https, www, and non ww versions of the site all different sites. We thought we fixed it, but for some reason https://www and just https:// are giving us duplicate content again.

I can't seem to figure out why it keeps doing this. The url is https://bandsonabudget.com if any of you want to see if you can figure out why I am still having this issue.

It looks like you have canonical URL meta information in place. However, there is no 301 redirect from the non-ww version to the www version.

For instances such as this, you want users to resolve to a single URL, which I believe you want the www version of the URL. You should implement a 301 redirect from the non-www to the www URL.

Also, in your Google Webmaster Tools, make sure to configure the setting that tells Google what your preferred domain/home page is.

This should help clear up any duplicate content issues for this case.
