Adding Arabic to a site is often treated as a translation task: take the English, swap the words, mirror the layout. That gets you something readable, but it rarely feels right to an Arabic reader.
Arabic-first design starts earlier. Text direction (RTL) affects how the eye moves, where navigation sits, which way icons point, and how numbers and English terms sit inside Arabic sentences. Forms, dates and alignment all need attention so nothing feels borrowed.
Typography matters too. Arabic needs fonts and spacing chosen for its shapes, not the defaults that suit Latin text. When this is done well, the page reads naturally instead of looking like a mirror image of an English site.
The payoff is trust. When an Arabic-speaking visitor lands on a page that was clearly built for them, they stay longer and take you more seriously, and that's worth getting right from the start.
