Hey guys, we are really big on SEO but noticed on all of our CMS hosted sites by webflow we fail in this category… Any thoughts or updates would be much appreciated!!!

URL Canonicalization Test
http://jaxnutcracker.org and http://www.jaxnutcracker.org/ should resolve to the same URL, but currently do not.
Doesn’t have anything to do with a cms hosted site, or not. Is generally a simple fix with an htaccess file telling which version of url you want. see #4 of this: https://moz.com/blog/htaccess-file-snippets-for-seos and also this: Consolidate Duplicate URLs with Canonical Tags | Google Search Central | Documentation | Google Developers
We flow hosting = no access to this file… . No friends access 
Select a primary domain in Site Settings > Custom Domains (click on the house icon), unpublish, then republish your site.
Genius! Thank you! So simple but yet I have never noticed that!
