Technical : Duplicate content and domain name change

[Kepass]

Hi guys,

So, this is a tricky one. My server team just made quite a big mistake :We are a big

We are a big magento ecommerce website, selling well, with about 6000 products. And we are about to change our domaine name for administrative reasons.

Let's call the current site : current.com and the future one  : future.com

Right, here is the issue

Connecting to the search console, I saw future.com sending 11.000 links to current.com. At the same time DA was hit by 7 points.

I realized future.com was uncorrectly redirected and showed a duplicated site or current.com. We corrected this, and future.com now shows a landing page until we make the domain name change.

I was wondering what is the best way to avoid the penalty now and what can be the consequences when changing domain name. Should I set an alias on search console or something ?

Thanks

Hi there

Moz actually created a fantastic migration guide that will give you a step by step process to properly move your website to it's new domain. I highly suggest reading it, as it goes into great detail and also includes a resources / tools list to help you and your team properly track performance. You can read all of that here.

Just wanted to let you know that this guide exists! I'm sure great answers are to follow! Hope this helps in the meantime, good luck!

Thanks Patrick,

I read that last year and it is the best ressource so far on the web. But I am not sure it applies to my case.

Thanks.
