Two identical URLs but different order in parameters: Duplicate content?

Question

My own CMS automatically adds new parameters to the links on the page to indicate the given language.

It works very well, but it does not always put var in the same position, which gives me a link to the same page / language:

www.xxx.yy / index.php mod = blog &? Page = 3 & Languages ​​= EP

or

www.xxx.yy / index.php mod = blog &? languages ​​= ep & page = 3

Will search engines be smart enough to detect both URLs as the same? Or will it show up as two different URLs and therefore mark them as duplicate content?

I’ll fix this problem anyway, but it’s been very interesting to me since ancient times.

Answer 1

Google definitely supports this, as it explicitly mentions this example on its webmaster blog :

As www.example.com/skates.asp?color=black&brand=riedellwell as www.example.com/skates.asp?brand=riedell&color=black. Having this type of duplicate content on your site can potentially affect the performance of your site, but it does not cause fines. From our article to duplicate content :

Duplicate content on a site is not a basis for action on this site unless it appears that the purpose of the duplicate content is to mislead and manipulate search engine results. If your site suffers from recurring content issues and you don’t follow the tips above, we’re doing a good job of selecting the version of the content to display in the search results.
