Welcome to the Q&A Forum

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. spam-analysis duplicate-content
