Big name companies often miss out on one of the basic concepts of SEO: Canonicalization, which means “identifying and consolidating to one, definitive source.” How are they missing out? Grab a handful of your favorite companies and see whether or not they have a https://www.yourdomain.com and a https://yourdomain.com that leads to the same page. You’d be surprised how many “culprits” there are out there that don’t have a 301 permanent redirect in place to preserve their home page’s Page Rank. By having two sets of pages out there, it creates duplicate content because the search engines see pages based on their URLs. So instead of splitting your Page Rank between two, identical URLs, take control over your traffic and make sure you have a 301 permanent redirect in place.
