Mixed English and Arabic URLs

[Guyboz]

I'm currently working with a global brand who need localisation in each of their territories.

They're operating on a single .com domain name, with different language versions in separate directories.

Example:
domain.com/en/
domain.com/fr/
domain.com/ar/

We're using ahreflang tags to make sure Google shows the correct language version for each region.

Now onto my question...

As the domain is a .com with an English company name, when it comes to the Arabic version of the website, will having a completely mixed language URL like this be detrimental to the site's performance in searches from the middle east?

Currently we're coming up with URLs like the following:

domain.com/blog/عنوان بلوق عربية طويلة حقا على شيء مثير جدا للاهتمام

Is this a bad thing?

Not at all, if the URL language matches the content of the page then it should be even better that using a full English URL.

However, I would suggest using domain.com/ar/blog/عنوان بلوق عربية طويلة حقا على شيء مثير جدا للاهتمام for the arabic blog and if there's an english or french version of that page, you can also implement hrelang on them and point them to domain.com/blog/English-blog-title-really-long-on-something-very-interesting

Hope that helps!
