Different results when running spam score tests with and without www in moz

[DarkoA]

Hey, can anyone help with this?

I am receiving extremely different results running spam score tests with and without www in moz. 
No www - is getting a spam score 8
And with www. is 1.

Should I be worried here, and how should I move to handle this?

Thanks in advance guys

Hi Darko,

It is important that you chose only one option for your website. If the www and non www versions of your website are working at the same time, you will have duplicated content issues. Chose the version that you are using into the host provider options for show your website (the one that has good inbound links). Also for Google those are completely different websites:

Where?

What properties?:
http://example.com/
https://example.com/
http://www.example.com/
https://www.example.com/

After all those were done:
Into this property only: https://www.example.com/ (Assuming that you prefer the https www version)
verify the robot texts
upload a sitemap
fetch as google

Good luck!

Hi there!

Thanks so much for the question! Sorry for any confusion here!

Your spam score in Open Site Explorer is partly based on your link profile in our Mozscape index which means that if sites are linking to you with the www version of your site and not the non-www version (or vice versa), the stats in Open Site Explorer will be based on those links. This would be why you’re seeing a different Spam score and other differing stats when you query the www vs non-www versions of your site.    Depending on your SEO strategy and your link building strategy, it may be worth monitoring both in OSE.

I also want to make sure to mention that unlike other metrics you see in OSE, the Spam Score isn’t updated monthly so some of the flags you’re seeing may not be relevant to your site anymore.  This score is updated much less frequently so we always recommend using your best judgement when looking at these- for example, if we’re flagging your site for not having contact info but you know it is there, you can ignore that flag.

I hope this helps! If you have any other questions or need any further help, please feel free to reach out to help@moz.com

Hi Darko,
Sorry, my above comment was more a solution than an explanation.
Due to for Google and Moz the www and the non www are different websites, you might have different spam score results. The same applies for the http and the https versions of a website.
As Meghan sayd, depending on the inbound links each version of your website has, the spam score result might differ each other.
Therefore, the solution is to chose one version, only one and force to that option ie no matter how is written the chosen option will be displayed. Which one? the one that already has better inbound links. If more than one version of your website has already inbound links, a good option is to set a permanent redirect - 301 - from one to the other, so to carry the "link juice". Hope this clarifies a bit.
