I use different languages like Arabic

Hello,

Thank you for contacting Rank Math for help with your questions.

First, have an application that supports Shopify been completed?

No, Rank Math is currently only available as a WordPress plugin.

I use the Arabic language in the title of the page (URL), do I have to use the Arabic language or use the English language because the Arabic language puts different symbols and its size is large
Does the URL hinder keyword rankings?

Please continue using Arabic URLs for Arabic language pages. The symbols you see are how browsers process non-latin characters and will not affect your SEO. If you want check that the symbols are giving the correct URL, you can use a tool like https://www.url-encode-decode.com/

Hope that helps. Please let us know if you have questions.
