Multiple Domains for Same Website: Duplicate Content Issue?

Visitor ✭ ✭ ✭

Have an website on "mydomain.NET" with years of established traffic. Recently purchased the domain "mydomain.COM". Have just recently binded both domains to the website under IIS 8. Want to make sure that all links will redirect to the domain "mydomain.COM" moving forward.

 

Concerns of "duplicate content" penalties have been brought to my attention. What is the best way to handle this redirect so not to lose any linking authority? A "301 redirect" ? (if yes, need references to set this up properly in IIS). 

 

Would appreciate your insight on this matter.

 

Thank you.

Here's an idea:

1) Ensure your old domain is 301 redirected at the root to the new domain name

2) Add both accounts to Google Search Console (GSC) (https://www.google.com/webmasters)

3) Verify each domain in GSC

4) Set a "Change of address" for the old domain (https://support.google.com/webmasters/answer/83106)

5) Submit your new site and sitemap on the new domain (this should clear up all old traffic and SERPs to now show new domain)

 

 

Shouldn't have any issues with duplicate content.  Smiley Happy

While testing, added a 301 redirect (permanent) to the website in IIS using “HTTP Redirect” but the website stopped working. Believe that the issue is that both domains are bound (“binded”) to this same website [possibly causing an infinite loop (?)].

 

To possibly resolve this, could clone ("duplicate") the website directory and assign to a new IIS website bound only to the ".com" domain. The only concern is that this would possibly reflect "duplicate content" based on the two different websites with the exact same content.

 

Uncertain how Google perceives having the same domain name with different domain suffixes redirected to the same website content.

 

Also, if there anyway to get the established and existing authority and page link metrics transferred from the .NET to the .COM website?

 

Your insight is appreciated. Thanks.

To make it even simpler, you can typically 301 redirect an entire domain at the registrar level.  An example is here and here:

Super simple, keeps you from having to worry about carrying that through on IIS.
