Core Web Vitals do not care which direction your text runs, but the way Arabic sites are usually built puts pressure on exactly the metrics Google watches.

Heavy fonts hurt the largest contentful paint. Late-loading layout blocks cause the shifts that wreck cumulative layout shift. Both are common when the Arabic version is bolted on late.

We fix them at the source. Fonts are subset and preloaded, images carry explicit dimensions, and the layout reserves space so nothing jumps as it loads.

We report the numbers on real devices before launch. A green score on a fast laptop in the office means little to a visitor on mobile data.
