Just got another question by a user about www vs non-www, which is better for SEO (Search Engine Optimization)? If you have any question regarding SEO, SMO, etc. can ask @immonazir (Twitter)
First of all I would like to say, there has no preference whether you use non-www or www in your SEO part. It’s your personal preference. But, yes there are some technical aspects of using www or without www which will cover later.
What are the SEO benefits of using Non WWW vs WWW?
As per the case study, there’s no SEO benefit or advantage of using non-www or www. Search Engine didn’t give the preference to rank a site on basis of practicing this. However, Google says use either www or non www in order to treat as a unique site.
If you’re using both options, search engine looks as two different sites with same contents, pages, keywords, etc. and these could ban to get rank over search engines.
Set your preferred domain (www or non-www) through Search Console
1) Sign in at: https://www.google.com/webmasters
2) Go to the Setting tab, just over the right corner of the logged in page.
3) Click on – Site Setting
4) Set your preferred domain
