Writing in Hebrew is a bitch. Even for me, and I was born in Israel.
So marketers often have a problem with Hebrew websites (cause they live and work in Israel). The URLs are headaches, since the internet places % (percentage sign) between every word. It’s just too confusing for the web, this silly language (again, I’m a native Hebrew speaker). It happens of course only when Hebrew words are appearing in the URL string of pages.
Ok, so the tip here, to avoid it is… place a hyphen (which is this -) before the URL and the world wide web tools will read it as it is without ruining it all over the place. This is relevant for placing it in Facebook posts, adverts and any other web tool you’re copying an URL to.
Good Luck!
